Background & Objectives: The present investigation is intended to prepare a Poly Herbal Formulation (PHF) with Piper nigrum (fruits), Terminalia paniculata (bark) and Bauhinia purpurea (bark) and assess their antioxidant and glucose-lowering effects utilizing in vitro models. Methods: The individual plant methanolic extracts and PHF are exposed to phytochemical examination and to distinguish the bioactive factors by GC-MS. We assessed the antioxidant properties of individual plant extracts and the PHF by using the DPPH scavenging method, H2O2 scavenging assay, TBARS assay and total antioxidant estimation. Likewise, the anti-diabetic activity was assessed by ɑ-amylase and α-glucosidase enzyme inhibition and glucose diffusion inhibitory techniques. Results: We found that PHF contains a high measure of total phenolics, total flavonoids and tannin compared to individual plant extracts. The GC-MS identified the bioactive components. We also found that PHF had significantly higher antioxidant and glucose-lowering effects than the individual plant concentrates. Conclusion: In conclusion, it could be reasoned that due to the nearness of antioxidant components, the PHF has good potential in the administration of hyperglycemia, diabetes and the related state of oxidative stress. This study shows that PHF is superior to individual plant extracts, supporting the conventional PHF concept.

In diabetes, the postprandial phase is characterized by a rapid and large increase in blood glucose levels, and the possibility that the postprandial “hyperglycemic spikes” may be relevant to the onset of cardiovascular complications has recently received much attention. Medicinal use of herbal medicine in the treatment and prevention of diseases including diabetes has a long history compared to conventional medicine. These plants have no side effects and many existing medicines are derived from the plants. Hence, the current investigation was planned to make a poly herbal drug (PHD) through Punica granatum (fruits), Illicium verum (flowers) and Nyctanthes arbor (leaves) and assess their antioxidant and antidiabetic activities in vitro and in HepG2 cell line. The respective plant methanolic extracts and PHD are exposed to phytochemical assessment and to discriminate the bioactive factors by Gas Chromatography–Mass Spectrometry. We evaluated the antioxidant properties 2, 2-diphenyl-1-picrylhydrazyl scavenging, hydrogen peroxide scavenging, thiobarbituric acid reactive substances and total antioxidant activity of individual plant extracts and the PHD. At the same time, In vitro and cell culture approaches were used to assess the anti-diabetic activity. The PHD has a higher concentration of secondary metabolites than individual plant extracts, according to our findings. On the other hand, we also notice that PHD demonstrated higher antioxidant capability and considerable in vitro glucose-lowering effects along with noteworthy inhibition of ɑ-amylase, glucosidase, lipase, dipeptidyl peptidase-IV, collagenase and protein glycation in HepG2 cell line. In conclusion, this study clearly demonstrated the significant antioxidant and antidiabetic activities of the PHD. Hence, PHD may be used as a potential source in the management of diabetes, hyperglycemia and the related state of oxidative stress.

In vitro models are often used for studying macrophage functions, including the process of phagocytosis. The application of primary macrophages has limitations associated with the individual characteristics of animals, which can lead to insufficient standardization and higher variability of the obtained results. Immortalized cell lines do not have these disadvantages, but their responses to various signals can differ from those of the living organism. In the present study, a comparative proteomic analysis of immortalized PMJ2-R cell line and primary peritoneal macrophages isolated from C57BL/6 mice was performed. A total of 4005 proteins were identified, of which 797 were quantified. Obtained results indicate significant differences in the abundances of many proteins, including essential proteins associated with the process of phagocytosis, such as Elmo1, Gsn, Hspa8, Itgb1, Ncf2, Rac2, Rack1, Sirpa, Sod1, C3, and Msr1. These findings indicate that outcomes of studies utilizing PMJ2-R cells as a model of peritoneal macrophages should be carefully validated. All MS data are deposited in ProteomeXchange with the identifier PXD022133.

UV irradiation is one of the main causes of extrinsic skin aging. UV-mediated skin aging, also known as photoaging, causes excessive breakdown of extracellular matrix which leads skin to lose its elasticity and strength. Several phytochemicals are known to exert anti-photoaging effects via different mechanisms, partly due to their antioxidant properties. The current study has been carried out to determine the potential anti-photoaging properties of myricetin 3-O-β-d-galacto-pyranoside (M3G), a flavonol glycoside isolated from L. tetragonum, in UVA-irradiated in vitro models; HaCaT keratinocytes and human dermal fibroblasts (HDFs). UVA-induced changes in MMP-1 and collagen production have been observed in HaCaT keratinocytes and HDFs. Further, UVA-induced activation of MAPK signaling, and pro-inflammatory cytokine production have been investigated. TGFβ/Smad pathway has also been analyzed in UVA-irradiated HDFs. Treatment with M3G reversed the UVA-induced changes in MMP-1 and collagen production both in HaCaT keratinocytes and HDFs. UVA-mediated activation of p38, ERK and JNK MAPK activation was also inhibited by M3G treatment in HaCaT keratinocytes. In HDFs, M3G was able to upregulate the TGFβ/Smad pathway activation. In addition, M3G downregulated the UVA-induced pro-inflammatory cytokines in keratinocytes and HDFs. It has been suggested that the M3G has exerted potential antiphotoaging properties in vitro, by attenuating UVA-induced changes in MMP-1 and collagen production in keratinocytes and dermal fibroblasts.

Diabetes mellitus is a serious health problem worldwide that has adverse and long-lasting consequences for individuals, families, and communities. Hence, this study sought to investigate the inhibitory potential of rosemary extracts on key-enzymes related to diabetes such as α-amylase and pancreatic lipase activities, as well as to assess their antioxidant properties in vitro. The IC50 values of Rosemary essential oil, ethyl acetate and methanolic extracts against α-amylase were 28.36, 34.11 and 30.39 µg/mL respectively, and those against pancreatic lipase were 32.25, 36.64 and 34.07 µg/mL, suggesting strong anti-diabetic and anti-obesity effects of Rosemary. The methanolic extract was found to be the highest in levels of phenolic (282.98 µgGAE/mg extract) and flavonoids (161.05 µg QE /mg extract) contents as well as in the antioxidant activity (IC50 = 15.82 µg/mL) as compared to other extracts ethyl acetate (IC50 = 32.23 µg/mL) and essential oil  (IC50 = 96.12 µg/mL).Antioxidant efficacy of Rosemary extracts has been estimated in the stabilization of sunflower oil (SFO) at three different concentrations, i.e. 200 (SFO-200), 500 (SFO-500) and 1000 ppm (SFO-1000). Results showed the highest efficiency of SFO-1000.The results obtained in this study demonstrated for the first time that Rosemary is a potent source of natural inhibitors of α-amylase and pancreatic lipase with powerful antioxidants proprieties that might be used in the food stabilization and the prevention of diabetes and obesity complications as a complementary pharmacological drug.

The aim of this study was evaluated the Antimicrobial Activity of extraction of Datura innoxia (Seeds, leaves and roots). Datura innoxia Seeds, leaves and roots were collected to examine their antimicrobial activity. Extracts of different parts of the plant were tested against standard microorganisms by using the agar- well diffusion method. Extracts of methanol, and aqueous of seeds, leaves and roots were prepared and tested against four types of bacteria namely: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Proteus vulgaris and two types of fungi namely: Aspergillus niger and Candida albicans. The methanolic and aqueous extracts of leaves showed high activities against fungi (A. niger) and less effect on the all bacteria. The methanolic extracts of seeds showed high activities against all organisms except fungi (C. albicanas), while the aqueous extracts of seeds showed no activity on the bacteria. All organisms were examined against known standard antibiotics and then compare the results of plant extracts with standard antibiotics. The results indicated that the antibacterial drug is less active than the plant extracts, while the antifungal drugs are more active than the plant extracts.

Abstract Wood species resistant to biodegradation by fungi contain phenolic compounds with proven fungicidal activity. Saprophytic fungi are able to colonize wood and later begin to break down its polymeric components through metal-dependent reactions. These generate free radicals at the onset of the degradation process. Later on, extracellular enzymes are active that use metallic cofactors. Five lignans were isolated from the methanolic extracts of the Chilean heartwoods (Austrocedrus chilensis, Fitzroya cupressoides, and Pilgerodendron uviferum) belonging to the Cupressaceae: isotaxiresinol, secoisolariciresinol, isolariciresinol, didemethylmatairesinol, and matairesinol. Their structures were determined spectroscopically. The antioxidant activity of the methanolic extracts and the isolated compounds was determined in vitro against the radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) and their iron-chelating capacity was evaluated by the Chrome Azurol S assay. All isolated methanolic extracts and lignans exhibited antioxidant activity against DPPH and Fe-chelating capacity with values greater than 87%. This may be interpreted that the antioxidant properties and metal-chelating capacity of these compounds have a protective effect on the wood of these species when exposed to attacks by saprophytic fungi.

Antinociceptive Effects

The objective of the present study was to evaluate the antinociceptive effects of phytol using chemical and thermal models of nociception in mice and to assess its antioxidant effects in vitro. Phytol was administered intraperitoneally (i.p.) to mice at doses of 25, 50, 100, and 200 mg/kg. In the acetic acid-induced writhing test, phytol significantly reduced the number of contortions compared to the control group (P<0.001). In the formalin test, phytol reduced significantly the amount of time spent in paw licking in both phases (the neurogenic and inflammatory phases), this effect being more pronounced in the second phase (P<0.001). Phytol also provoked a significant increase in latency in the hot plate test. These antinociceptive effects did not impaire the motor performance, as shown in the rotarod test. Phytol demonstrated a strong antioxidant effect in vitro in its capacity to remove hydroxyl radicals and nitric oxide as well as to prevent the formation of thiobarbituric acid reactive substances (TBARS). Taken as a whole, these results show the pronounced antinociceptive effects of phytol in the nociception models used, both through its central and peripheral actions, but also its antioxidant properties demonstrated in the in vitro methods used.

Abstract Background Ectoparasites of livestock in general and lice in particular pose serious economic losses to the farmer, the tanning industry, and the country as a whole. Although the treatment of ectoparasites have been attempted by various chemical agents, the efficacy of the agents hampered by the development of drug resistance. Thus, Ethnoveterinary botanicals are an alternative control strategy for being sustainable and ecologically sound. Thus, this study aims to evaluate the louscidal activity of crude methanolic extracts of Calpurnea aurea and Schinus molle plants against the cattle lice, Linognathus vituli using the in vitro Adult Immersion Test (AIT). Six graded concentrations of the crude extracts, 6.25, 12.5, 25, 50, 100 and 200 mg/ml, were tested at different time intervals, and temporal changes in tick viability were recorded for 24 hours. Results After 24hrs post-exposure, two higher concentrations (200 and 100 mg/ml) of C. aurea extract caused 100±0.0% and 96.6±3.3% lice mortality, whereas S. molle extract caused 90±5.7% and 83.3±3.3% mortality, respectively. Louscidal activity varies with the type of plant extract, concentration and exposure time. After 24 hours of exposure to the extracts, the highest mortality was recorded for extracts from C. aurea with LC50 values of 8.83 mg/ml compared to S.molle with LC50 values of 16.68 mg/ml. Conclusions The louscidal activity of the plant extracts increases with increasing exposure time and concentration as well. Thus, the plant extracts could be used against Linognatus vituli as a potential alternative for the control of lice.
