This research work explains the antioxidant and anti-atherogenic effects of selected Siddha polyherbal decoctionssuch as Nilavembukudineer, Kabasurakudineer, NotchikudineerandAdathodaikudineer. Even though all the above decoctions have been used for fever, cold, cough, bronchitis, dysphonea and body pain in Siddha system of medicine, their antioxidant and anti-atherogenic properties were notinvestigated scientifically.We have analyzed the polyphenolic content, antioxidant and anti-atherogenic properties of decoction of the above-mentioned herbal formulations. The toxicity of the decoctions was also performed in PMBC.Inthe investigated formulations, Notchikudineershowed higher level of total phenolic content (560 mg GAE/100 g), followed byAdathodaikudineer (260 mg GAE/100 g),Nilavembukudineer(150 mg GAE/100 g) and Kabasurakudineer(90 mg GAE/100 g). Similarly, Notchikudineer exhibited strong antioxidant activity in terms of radical scavenging potential against DPPH (IC-50: 2.12 mg/L), followed the Adathodaikudineer (IC-50: 2.27 mg/L),Nilavembukudineer(IC-50: 4.48 mg/L) and Kabasurakudineer (IC-50: 9.29 mg/L).In toxicological study all the decoctions of selected formulations didn’t show any toxicity.Similarly, Nilavembukudineer showed maximum inhibition of lipid peroxidation when compared to other herbal decoctions. Among the investigated Siddha formulations, Nilavembukudineer was found to possess high antioxidant and anti-atherogenic potentials and hence it could be further investigated as anti-atherogenic drug using in vivo model.

Abstract Background The objective of the study is to evaluate the hepatoprotective activity of methanolic extract fractions of Lindernia ciliata (LC) and development of qualitative analytical profile of the bioactive fraction using HPLC fingerprinting analysis. All the fractions of methanolic extract of Lindernia ciliata (LCME) are assessed for their total phenolic, flavonoid contents and in vitro antioxidant properties by using DPPH, superoxide, nitric oxide, hydroxyl radical scavenging activities and reducing power assay. Acute toxicity study was conducted for all the fractions and the two test doses 50 and 100 mg/kg were selected for the hepatoprotective study. Liver damage was induced in different groups of rats by administering 3 g/kg.b.w.p.o. paracetamol and the effect of fractions were tested for hepatoprotective potential by evaluating serum biochemical parameters and histology of liver of rats. The effective fraction was evaluated for its antihepatotoxic activity against D-Galactosamine (400 mg/kg b.w. i.p.) and in vivo antioxidant parameters viz., Glutathione (GSH), Melondialdehyde (MDA) and Catalase (CAT) levels are estimated using liver homogenate. Results Among all the fractions, butanone fraction of LCME, (BNF-LCME) has shown better hepatoprotective activity and hence it is selected to evaluate the antihepatotoxicity against D-GaIN. The activity of BNF-LCME is well supported in in vitro and in vivo antioxidant studies and may be attributed to flavonoidal, phenolic compounds present in the fraction. Hence, BNF-LCME was subjected to the development of qualitative analytical profile using HPLC finger printing analysis. Conclusions All the fractions of LCME exhibited significant hepatoprotective activity and BNF-LCME (50 mg/kg) was identified as the most effective fraction.

The antioxidant activities of crude extract ofPhaulopsis fascisepalaleaf were evaluated and compared with α-tocopherol and BHT as synthetic antioxidants and ascorbic acid as natural-based antioxidant.In vitro, we studied its antioxidative activities, radical-scavenging effects, Fe2+-chelating ability and reducing power. The total phenolic content was determined and expressed in gallic acid equivalent. The extract showed variable activities in all of thesein vitrotests. The antioxidant effect ofP. fascisepalawas strongly dose dependent, increased with increasing leaf extract dose and then leveled off with further increase in extract dose. Compared to other antioxidants used in the study, α-Tocopherol, ascorbic acid and BHT,P. fascisepalaleaf extract showed less scavenging effect on α,α,-diphenyl-β-picrylhydrazyl (DPPH) radical and less reducing power on Fe3+/ferricyanide complex but better Fe2+-chelating ability. These results revealed thein vitroantioxidant activity ofP.fascisepala.Further investigations are necessary to verify these activitiesin vivo.

The in vitro and in vivo antioxidant activities and its potential to protect against amyloid-β toxicity of essential oils from Zelkova serrata (Thunb.) Makino were investigated in the model organism Caenorhabditis elegans. The results revealed that the essential oil of Z. serrata heartwood exhibited great radical scavenging activities and high total phenolic content. In vivo assays showed significant inhibition of oxidative damage in wild-type C. elegans under juglone-induced oxidative stress and heat shock. Based on results from both in vitro and in vivo assays, the major compound in essential oil of heartwood, (-)-(1 S, 4 S)-7-hydroxycalamenene (1 S, 4 S-7HC), may contribute significantly to the observed antioxidant activity. Further evidence showed that 1 S, 4 S-7HC significantly delayed the paralysis phenotype in amyloid beta-expressing transgenic C. elegans. These findings suggest that 1 S, 4 S-7HC from the essential oil of Z. serrata heartwood has potential as a source for antioxidant or Alzheimer's disease treatment.

Ruta angustifolia was used in this study in order to evaluate the antimicrobial activity and antioxidant properties and its correlation with the polyphenolic content. Two Gram-positive bacteria (Staphylococcus aureus ATCC 25923, Bacillus cereus ATCC 11778) and two Gram–negative bacteria (Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 8739) were used to determine the antibacterial activity. Aqueous maceration extract was used for antioxidant activities and methanolic maceration extract was used for antibacterial activity. The antioxidant properties and activities were evaluated by using total phenolic content (TPC), total flavonoid content (TFC), DPPH free radical scavenging activity and beta-carotene bleaching method. Whereas, the antibacterial activity was examined using disc diffusion method against selected microorganism at concentration 1.0 mg/disc. The results showed the phenolic content of R. angustifolia extract was 18.89 g GAE/100 g extract while the flavonoid content was 14.170 g QE/100 g extract. R. angustifolia exhibited good radical scavenging with IC50 value of 2.04 mg/ml. The result for disc diffusion method showed no inhibition zone against all the strains of bacteria at 1.0 mg/disc concentration of the extract. Based on the results, it can be concluded that the R. angustifolia aqueous extract has the antioxidant properties and there is correlation between polyphenolic content of the extract with its antioxidant activity. However, R. angustifolia methanolic extract did not show any antibacterial activity.

The present study was conducted to evaluate the antioxidant, antidiarrheal and analgesic activities of Vachellia farnesiana (L.) Wight & Arn. The methanol extract of V. farnesiana and its different fractionates were subjected to in-vitro assay for the determination of total phenolic content and antioxidative potential. The ethyl acetate soluble fraction (EASF) exhibited the highest free radical scavenging capacity (IC50 value of 21.49 ± 1.04 μg/ml) as compared to that exhibited by the standard butylated hydroxyl toluene (BHT) (IC50 value of 20.41 ± 0.05 μg/ml). Such prominent antioxidative potential was further reinforced by a phenolic content of 39.26 ± 0.85 mg of gallic acid equivalent per gram of extract. The plant extract, at the dose of 400 mg/kg body weight, reduced castor oil-induced diarrhea in mice model by a statistically significant (p < 0.05) margin of 47.62%, while the standard loperamide produced 66.67% reduction of diarrheal feces. The central and peripheral analgesic activities of the crude methanol extract of V. farnesiana (MEVF) was determined by tail flick- and acetic acidinduced writhing methods, respectively, in Swiss albino mice. In the tail flick method, oral administration of MEVF at doses of 200 and 400 mg/kg body weight exhibited 221.09 and 237.09% elongation of pain response time, respectively, after 90 minutes of administration whereas the standard morphine effectuated 518.34% elongation within the same time. Furthermore, the same doses of the extract illustrated 63.27 and 69.39% reductions, respectively, in the acetic acid-induced abdominal constrictions in mice. Compared to the standard acetylsalicylic acid with 75.51% inhibition, statistically significant (p < 0.05) peripheral analgesic activity was established. The results of the present investigations suggest that methanol extract of V. farnesiana possesses antioxidant, antidiarrheal and analgesic activities which eventually indicates the presence of biologically important phytoconstituents within the plant that needs further exploration.

Abstract Background Hyperglycemia is the hallmark of diabetes, and the associated oxidative stress is a major concern that invites an array of diabetic complications. The traditional practices of medicare are of great, current interest due to the high cost and side effects of conventional diabetic medications. The present in vitro study focuses on evaluating the potential of various A. occidentale root extracts for their antihyperglycemic and antioxidant potentials. Materials and methods The four different solvent extracts petroleum ether (PEAO), chloroform (CHAO), ethyl acetate (EAAO), and 80 % methanol (80 % MAO) of A. occidentale roots were evaluated for their total phenolic, flavonoid, and antioxidant capacity. Using MIN6 pancreatic β-cells, the cytotoxicity of the extracts was evaluated by MTT assay and the antidiabetic potential by quantifying the insulin levels by ELISA at a higher concentration of glucose. The effect of 80 % MAO on INS gene expression was determined by qRT PCR analysis. Results Among the four different solvent extracts of A. occidentale roots, 80 % MAO showed the highest concentration of phenolics (437.33 ± 0.03 µg GAE/mg), CHAO to be a rich source of flavonoids (46.04 ± 0.1 µg QE/mg) and with the highest total antioxidant capacity (1865.33 ± 0.09 µg AAE/ mg). Evaluation of the free radical scavenging and reducing properties of the extracts indicated 80 % MAO to exhibit the highest activity. The MTT assay revealed the least cytotoxicity of all four extracts. 80 % MAO enhanced INS up-regulation as well as insulin secretion even under high glucose concentration (27mM). Conclusions The present study demonstrated that the A. occidentale root extracts have effective antihyperglycemic and antioxidative properties, together with the potential of normalizing the insulin secretory system of β-cells. Above mentioned properties have to be studied further by identifying the active principles of A. occidentale root extracts and in vivo effects. The prospect of the present study is identifying drug leads for better management of diabetes from the A. occidentale root extracts. Graphical abstract

The aim of this study was to investigate in-vitro antioxidant properties and in-vivo protective effects of different concentrations of Hypericum triquetrifolium Turra. (HT) seed methanol extracts against acute hepatotoxicity, myelotoxicity and hematotoxicity in rats exposed to overdose of cyclophosphamide (CP). HT seed methanol extracts were tested in view of its in-vitro antioxidant activities as total phenolic contents and DPPH free radical-scavenging activity. To investigate in-vivo protective effects of HT seed methanol extracts on rat tissues; tested animals were divided into nine groups. Three groups only were treated with HT extracts (25, 50 and 100 mg/kg HT) for 6 days. Three groups were pre-treated with the extract of HT (25, 50 and 100 mg/kg HT) for 6 days and on the last day they were injected with single dose of CP (150-mg/kg body weight). Two groups were used as control groups and one group was only treated with CP (150 mg/kg) on the 6th day. The toxic effects of CP and protective effects of HT extracts on the nucleated cells which were produced by bone marrow and serum alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), oxidative stress index (OSI) levels were investigated biochemically. Additionally, liver tissue samples were examined histopathologically. Our results show that HT seed methanol extract has high total phenolic content and antioxidant activity. Over dose CP administration caused hepatotoxicity, myelotoxicity and hematotoxicity on rat. Whereas, 25, 50 and 100 mg/kg HT plus CP administered groups showed significant protective effects on nucleated cells. And 25, 50, 100 mg/kg HT plus CP treated groups showed an important decrease on serum ALT, ALP, LDH and OSI levels when compared with CP treated group. Our results showed that the administration of different HT doses with high doses of CP significantly reduced hepatotoxicity, myelotoxicity and hematoxicity on rats.

Introduction: Neuroactive herbal drugs enriched with antioxidants are valuable in treating neurocognitive dysfunction and Vaccinium corymbosum, enriched with antioxidant phytochemicals, is used for treating memory disorders. Hence, the present study evaluated the neuroprotective effects of ethanolic extract of Vaccinium corymbosum (EEVC) on aluminium chloride(AlCl3)-induced Alzheimer’s type of dementia and haloperidol-induced catalepsy-associated behavioural changes. Methods:In vitro antioxidant potential was evaluated using 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS). The total phenolic content (TPC) was quantified. For in vivo studies, AlCl3 (100 mg/kg) was orally administered for 42 days, whereas the EEVC was administered on the 21st day until the 42nd day in two doses (200 mg/kg and 400 mg/kg). In the haloperidol-induced group, EEVC was treated for 21 days, and haloperidol (1 mg/kg) was administered to induce behavioural changes. Open-field, Y-Maze and traction tests were performed, and the mice brain acetylcholinesterase (AChE) enzyme was determined. Results: IC50 values in DPPH and ABTS assays were 85.5 μg/mL and 80 μg/mL, respectively and the total phenolic content of EEVC was found to be 0.166 mg. In a behavioral study, animals treated with 200 mg/kg and 400 mg/kg of EEVC exhibited a neuroprotective impact on AlCl3-induced neurodegeneration and haloperidol-induced behavioral changes with significant inhibition (P < 0.05 and P < 0.01, respectively) in acetylcholinesterase enzyme. Conclusion: The neuroprotection by EEVC postulated that it is a promising therapeutic agent for treating behavioral and cognitive dysfunctions. Further investigations on pro-inflammatory cytokine and neuroendocrine regulation in transgenic Alzheimer’s disease (AD)models complement the therapeutic value of V. corymbosum.

Diploknema butyracea (Roxb.) H.J. Lam is a multipurpose tree used by the Nepalese indigenous people for medicinal purposes such as rheumatism, asthma, and ulcer and other purposes such as cooking and lighting. However, there is no scientific evidence for the medicinal uses of this plant. The present study aimed to explore the phytochemical constituents, estimate the total phenolic content, evaluate antioxidant activity, and investigate the in vivo anti-inflammatory and analgesic activities of aqueous extract of Diploknema butyracea (Roxb.) H.J. Lam bark (ADBB). Phytochemical screening was performed using standard methods. The total phenolic content was determined using the Folin–Ciocalteu method. The in vitro antioxidant activity was determined using 2, 2-diphenyl-1-picrylhydrazyl radical scavenging assay and nitric oxide radical scavenging assay. For the in vivo studies, the plant extract was given in three different doses (50, 100, and 200 mg/kg body weight) to male albino Wistar rats. Anti-inflammatory and analgesic studies were carried out using the carrageenan-induced rat paw edema and the hot plate method, respectively. Results revealed the presence of different phytoconstituents such as flavonoids, tannins, glycosides, terpenoids, and carbohydrates together with a considerable amount of phenolic compounds. Antioxidant assays indicated the potent antioxidant activity of the plant extracts. The higher dose of D. butyracea (200 mg/kg) exhibited a maximum and significant inhibition (53.20%) of rat hind paw edema volume at 4 h and showed a greater increment in latency time (12.15 ± 1.81 sec) in the hot plate test at 120 min. The present study demonstrated the antioxidant, anti-inflammatory, and analgesic potential of ADBB, which supports its traditional medicinal use.
