Abstract Abrus precatorius is a widely distributed tropical medicinal plant with several therapeutic properties, however its seed extract has not been studied against cervical cancer (CaCx) till date. Herein, we have assessed the antioxidant and antiproliferative properties of A. precatorius seed extracts (ethyl acetate and 70% ethanol) prepared from different extraction methods (Soxhlet and maceration) against human cervix carcinoma cells (Hep2C). We observed a significantly higher total flavonoid content of APE (sox) i.e.,112.7±0.127 mg Quercetin Equivalent/g of extract than others; total phenolic content of APA (mac) seed extract was higher i.e.,108.53±0.089 mg Quercetin Equivalent/g of extract and total tannin content of APA (sox) was higher i.e., 98.98± 0.011 mg tannic acid equivalents/g of extract. In addition, tannic acid, rutin and piperine were identified in extracts by HPLC. Furthermore, APA (sox) exhibited the highest radical scavenging activity with an IC50 value of 14.49±0.93µg/ml. APE (mac) showed the most significant antiproliferative activity with IC50 value of 85.90±0.93µg/mL against Hep2c cells. SOD and GST activity was observed as highest in the APA(Mac) extract whereas the catalase activity and GSH content was maximum in the APE(Mac) extract. Further, the MDA content was observed to be the least in APE(Mac) extracts. Docking results suggested maximum binding energy between tannic acid and Her2 receptor compared to doxorubicin (standard). This study provides evidence that A. precatorius seed extracts possess promising bioactive compounds with probable anticancer and antioxidant properties against CaCx which might be utilized as a possible herbal remedy aimed at restricting tumor growth.

Sorghum is a major cereal food worldwide, and is considered a potential source of minerals and bioactive compounds. Its wide adaptive range may cause variations in its agronomic traits, antioxidant properties, and phytochemical content. This extensive study investigated variations in seed characteristics, antioxidant properties, and total phenolic (TPC) and flavonoid contents (TFC) of sorghum collected from different ecological regions of 15 countries. The antioxidant potential of the seed extracts of various sorghum accessions was determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azinobis 3-ethylbenzothiazoline-6-sulfonate (ABTS) radical scavenging assays. Significant variations in TPC were observed among the sorghum accessions. All 78 sorghum accessions used in this study exhibited significant variations in TFC, with the lowest and highest amount observed in accessions C465 and J542, respectively. DPPH scavenging potential of the seed extracts for all the accessions ranged from 11.91 ± 4.83 to 1343.90 ± 81.02 µg mL−1. The ABTS assay results were similar to those of DPPH but showed some differences in the accessions. Pearson’s correlation analysis revealed a wide variation range in the correlation between antioxidant activity and TPC, as well as TFC, among the sorghum accessions. A wide diversity range was also recorded for the seed characteristics (1000-seed weight and seed germination rate). A dendrogram generated from UPGMA clustering, based on seed traits, antioxidant activity, TPC, and TFC was highly dispersed for these accessions. Variations among the accessions may provide useful information regarding the phytoconstituents, antioxidant properties, and phytochemical contents of sorghum and aid in designing breeding programs to obtain sorghum with improved agronomic traits and bioactive properties.

Nephelium mutabile is a tropical plant of Sapindaceae family which originated from the Malay Peninsula and used in traditional medicine. This study focused on investigating the antioxidant and anti-diabetic properties of Nephelium mutabile leaves. The aqueous methanol (80%) crude extract of Nephelium mutabile leaves were fractionated via gravity column chromatography and thin-layer chromatography. A total of 17 fractions were obtained from column chromatography and subsequently pooled together to yield eight fractions. The pooled fractions were examined for their antioxidant properties via DPPH assay, Folin-Ciocalteu assay, and aluminum chloride colorimetric assay and tested for anti-diabetic properties using alpha-amylase and alpha-glucosidase inhibitory assay. DPPH assay showed that fraction 8 has the highest free radical scavenging activity (EC50 =88.0 μg/mL) followed by fraction 7 (EC50 =225.0 μg/mL). Fraction 8 showed the highest total phenolic and flavonoid content (221.1 μg GAE/mg, 222.4 μg QE/mg) respectively followed by fraction 7 (166.5 μg GAE/mg, 213.9 μg QE/mg) respectively. The most potent alpha-amylase inhibitory activity is observed in fraction 8 with an IC50 value of (41.0 μg/mL) followed by fraction 7 (90.6 μg/mL). In the alpha-glucosidase inhibitory activity, fraction 8 with IC50 value 160.0 μg/mL followed by fraction 7 with IC50 value 50.6 μg/mL showed the best inhibition activity. In conclusion, Nephelium mutabile leaves showed potential antioxidant, and anti-diabetic properties and fractions 8 and 7 should be the focus of future studies.

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 Mongolian rhubarb—Rheum undulatum L. (RU)—and Rumex crispus L. (RC)—a Taiwanese local rhubarb belonging to the family of Polygonaceae—are principal therapeutic materials in integrative medicine due to their rich quantities of bioactive compounds; however, their phytochemical and antioxidant properties, and anti-cancer activity is poorly investigated. Furthermore, the phytochemical characteristics of both species may be affected by their different geographical distribution and climatic variance. The current study aimed to compare RU with RC extracts in different polarity solvents (n-hexane, ethyl acetate, acetone, ethanol, and water) for their phytochemical contents including the total phenolic content (TPC), total anthraquinone content (TAC), total flavonoid content (TFC), antioxidant and free radical scavenging capacities, and anticancer ability on the HepG2 cell. Except for the n-hexane extract, all of the RU extracts had considerably higher TPCs than RC extracts, ranging from 8.39 to 11.16 mg gallic acid equivalent (GAE) per gram of dry weight, and the TPCs of each extract were also significantly correlated with their antioxidant capacities by ABTS, DPPH, and FRAP assays (p < 0.05). Moreover, there was no remarkable association between the antioxidant capacities and either TACs or TFCs in both the RU and RC extracts. Besides, high-performance liquid chromatography (HPLC) analysis revealed that both the RU and RC extracts contained chrysophanol, emodin, and physcion, and those bioactive compounds were relatively higher in the n-hexane solvent extracts. Additionally, we observed different levels of dose-dependent cytotoxic effects in all the extracts by cell viability assay. Notably, the ethanol extract of RU had a compelling cytotoxic effect with the lowest half-maximum inhibition concentration (IC50-171.94 ± 6.56 µg/mL at 48 h) among the RU extracts than the ethanol extract of RC. Interestingly, the ethanol extract of RU but not RC significantly induced apoptosis in the human liver cancer cell line, HepG2, with a distinct pattern in caspase-3 activation, resulting in increased PARP cleavage and DNA damage. In summary, Mongolian Rhubarb, RU, showed more phytochemical contents, as well as a higher antioxidant capacity and apoptotic effect to HepG2 than RC; thus, it can be exploited for the proper source of natural antioxidants and liver cancer treatment in further investigation.

Background: Research on medicinal plant antioxidants has emerged as a potential therapeutic to prevent free radical generated damage in the human body. Hammada elegans Botsch (popularly known as “Ajram”) is a xerophytic plant widely found in Laghouat region, but there are only a few reports about the biological or chemical properties of these species. Hence, the aim of this study is to investigate the antioxidant and the antihemolytic activities of hexanic, acetonic, methanolic and aqueous extracts of aerial parts of Algerian Hammada elegans Botsch by employing different in vitro assay systems. Methods: The total phenolic content, the flavonoid content and the condensed tannin amount were analyzed using Folin-Ciocalteu, aluminum chloride and vanillin assays, respectively. The in vitro antioxidant capacity of extracts was assessed by CUPRAC, iron chelating, ABTS•+and antihemolytic assays, and was expressed as EC50 values. Results: Among the analyzed extracts, the aqueous extract had the highest phenolic, flavonoid and tannin contents. Also, this extract displayed the highest antioxidant capacities compared to the other extracts and standards. Its EC50 value for ABTS radical-scavenging activity was 0.265 ± 0.003 mg/L. Moreover, this extract showed high iron (II) chelating ability (EC50 = 0.958 ± 0.001 mg/L), and good antioxidant activity in the cupric ion reducing activity (CUPRAC) in a concentration dependent manner (EC50 were 0.709 ± 0.002 mg/L). Additionally, this extract had the best antihemolytic activity against AAPH-induced hemolysis (EC50=0.090 ± 0.004 mg/L). Conclusion: Our study revealed that the aqueous extract of Hammada elegans Botsch, is a potential source of antioxidants which possess a high protective effect of membrane against free radical.

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.

Diarrhea is a common health complaint occurring with mild, temporary conditions to a potentially life-threatening condition. <i>Cucurbita maxima</i> (Cucurbitaceae) seed is reportedly used traditionally for the treatment of diarrheal and thus this study aimed to evaluate the in vitro antioxidants, total tannins, phenolics contents, and antidiarrheal potentials of <i>n</i>-hexane and aqueous <i>C. maxima</i> seed extracts in castor oil induced diarrheal rats. The <i>n</i>-hexane extract mainly contains oils while the aqueous extract was thick, brown solid. The aqueous and <i>n</i>-hexane seed extract of <i>C. maxima</i> expressed significant 2,2, diphenyl-1-picrythdrazyl (DPPH) scavenging activities at 6.25 – 1000 mg/mL with IC<sub>50</sub> values of 104.01 mg/mL, 29.27 mg/mL and 26.78 mg/mL for <i>n</i>-hexane, aqueous and vitamin C respectively. The hydroxyl radical scavenging activities of the <i>n</i>-hexane and aqueous seed extract of <i>C. maxima</i> were significantly lower at higher concentrations compared with that of vitamin C. Furthermore, the total antioxidant capacities of <i>n</i>-hexane (22.08mg/mL) and aqueous seed extract (11.03 mg/mL) of <i>C. maxima</i> were found to be higher than that of vitamin C (134.46 mg/mL). The aqueous extracts (658.33±380.08 mg QE/g) total tannins were not significantly different from the <i>n</i>-hexane extract (468.33±102.55 mg QE/g) while the <i>n</i>-hexane extract contains significantly higher total phenolics (2.93±1.25 mg GAE/g) compared with the aqueous extract (0.19±0.04 mg GAE/g). Percentage inhibition of stooling was found to be 57±22%, 41±16%, and 46±11% for loperamide, <i>n</i>-hexane, and aqueous respectively. The study concludes that aqueous and n-hexane seed extracts of <i>C. maxima</i> (pumpkin) possess in vitro antioxidant activities and antidiarrheal properties.
