Leaf extracts of Rauvolfia tetraphylla were evaluated for antifilarial potential using Setaria cervi as target parasite. Four extracts were tested these were hexane, chloroform, acetone and methanol. The activity was assessed by means of worm motility assay, MTT reduction and GST enzyme inhibition assay using female worms of Setaria cervi. DEC was used as a standard drug. Methanol extract exhibited significant activity among all the extracts with percentage of reduction 89.28% at 10mg/ml concentration. DEC was comparitively less active than methanolic extract with 79.22% activity at the same dose. The IC50 value for methanolic extract was found to be 0.03mg/ml, which was better than the standard DEC i.e. 2.84mg/ml. The methanol extract significantly inhibited the GST enzyme activity of Setaria worms as compared to untreated worms with percentage of inhibition value of 56.41% at 10mg/ml. The most active methanol extract was finally explored for cell viability study by using trypan blue dye exclusion test. The methanolic extract significantly killed the oocytes of Setaria worms as all the oocytes stained blue in treated worms and unstained in control oocytes. The findings indicate that the methanolic extract has potent macrofilaricidal ativity.

Histopathological studies of the effects of chloroform and methanolic leaf extracts of Ilex kudingcha in Trypanosoma brucei infected albino wistar rats were investigated. The toxicity and phytochemical study were also carried out using standard protocol. T. brucei infected animals were administered orally with 200 and 400 mg/kg b.w. of the extracts and 3.5 mg/kg b.w. of the standard drug (diminazene aceturate). Results on acute toxicity studies (LD50) revealed no sign of lethality up to the dose of 5,000 mg/kg body weight but the liver and kidney histology of infected animals treated with 5,000 mg/kg b.w. of I. kudingcha extracts were observed to be hepatotoxic and nephrotoxic. The methanol extracts showed appreciably high in vivo anti-trypanosomal activities compared to the reference drug. Histological examination of the organs revealed serious pathological lesions in the liver of the infected animals without treatment (negative control). In the positive control animals (infected animals administered standard drug), mild multifocal aggregate of inflammatory leucocytes was observed. In the other experimental animals, no pathological lesion was observed in the liver, kidney, brain, and heart of infected animals treated with the methanolic extract and combined methanol and chloroform extracts. The effectiveness of the methanolic extract at reducing the lesions caused by the parasite is the same compared with the standard drug. Phytochemical analysis of the plant extracts showed that methanol extract contained appreciable high levels of alkaloids, saponin, tannins, phenol, and glycoside while flavonoid was not detected. Hence, the curative properties of methanolic extract of I. kudingcha as observed in the organs indicate its anti-trypanosomal properties but it should be consumed at minimal doses.

The objective of the study was to investigate in-vitro antibacterial and antioxidant activities of methanolic extract of Combretum album Pers. root. In brief antibacterial efficacies of methanol extract and its petroleum ether fraction (MePET), chloroform fraction (MeCH), ethyl acetate fraction (MeEA) and water fraction (MeAQ) were determined by agar well diffusion assay along with Minimum Inhibitory Concentrations (MICs). In-vitro antioxidant efficacies were evaluated by DPPH radical scavenging method. Preliminary phytochemical assay, Fourier Transform Infrared Spectroscopy and Gas Chromatography-Mass Spectroscopy analyses were employed to detect the plausible active ingredients. Methanol extract showed broad spectrum antibacterial activity having highest inhibition zone against Staphylococcus aureus MTCC 2940 (21.67±0.58 mm) and MICs ranged from100 µg/ml to 250 µg/ml. The scavenging activity of methanol extract of root of C. album was concentration dependant and IC50 value was 136.08 µg/ml. The lowest MIC (5 µg/ml) was noted with MeCH against B. subtilis (MTCC 441). MeCH showed highest antioxidant activity with an IC50 value of 12.98 ?g/mL and MePET, MeEA, MeAQ and Ascorbic acid presented antioxidant potential with IC50 values of 16.10, 15.07, 17.44 and 13.40??g/mL respectively. Preliminary phytochemical tests and FT-IR analysis revealed presence of various phytochemicals and functional groups like hydroxyl, carboxylic acids, amidines, amines, aromatics and esters. Three compounds were elucidated from bioactive TLC fraction of MeCH in GC-MS analysis supported by presence of various functional groups in MeCH as detected in FT-IR analysis. It is concluded that methanolic extract of C. album root is a potential antibacterial and antioxidant agent where presence of N-[5-[4-pyridinyl)-1H-1,2,4-triazol-3-yl]-benzamide (compound 1), pyruvic acid (compound 2) and methyloacetone (compound 3) are responsible as possible active ingredients.

Abstract The species Eugenia involucrata DC. is a plant native to Brazil and is traditionally used for intestinal problems, however, little research has documented about its biological potential and phytochemical profile. Thus, the objective of this study was to carry out preliminary phytochemical prospecting, antimicrobial and antioxidant potential of E. involucrata extracts. Using the E. involucrata leaves, aqueous and organic extracts were obtained using the following solvents (ethanol, methanol, hexane, acetone, dichloromethane and ethyl acetate). The phytochemical prospecting detected the presence of saponins, steroids, flavonoids and tannins in the extracts. Ethanolic and methanolic extracts presented antimicrobial activity for most of the bacterial strains tested, as well as for yeast Candida albicans, with concentrations between 3.12 and 50 mg/mL. The ethanolic and metanolic extract presented high free radical sequestration potential (>90%). The methanol extract showed an IC50 value statistically equal to that found for the commercial antioxidant BHT (p <0.05). The crude extracts obtained with ethanol and methanol were the most promising. These results suggest that methanolic, ethanolic and aqueous extracts are a promising source of natural bioactive.

Gout is characterized as an inflammation and warmth in the joints. It is associated with hyperuricemia wherein an upregulation of xanthine oxidase in purine degradation leads to increased levels of uric acid in the blood. Gout is not fatal. However, it affects one’s quality of life. Thus, this research primarily focuses in determining the inhibitory activity of xanthine oxidase in the methanolic leaf extract of bitaog (Calophyllumblancoi), bolongeta (Diospyrospilosanthera), and duhat (Syzygiumcumini) in gout. A quantitative-experimental research method was used in the study and the data were obtained by measuring the percent inhibition of the samples using UV-Vis spectrophotometer at 290 nm. The results showed that the methanolic leaf extract of above stated plants exhibited exemplary inhibition in comparison with the standard drug, allopurinol. The IC50  value determines the ability of the inhibitor to decrease the biotransformation of a substrate. The principle behind IC50 is, the lower the value the higher the inhibition. The bitaog (Calophyllumblancoi) trials have the lowest IC50 value with an average of 124.3 after the standard drug, followed by bolongeta (Diospyrospilosanthera) have an average of 155.3 IC50 value. Then duhat (Syzygiumcumini) showed the highest IC50 an average of 208.8. The bitaog (Calophyllumblancoi), next to allopurinol, showed the highest inhibition among all the extracts followed by the bolongeta (Diospyrospilosanthera). The least inhibitory activity was observed in duhat (Syzygiumcumini). Hence, it can be concluded that bitaog (Calophyllumblancoi), bolongeta (Diospyrospilosanthera), and duhat (Syzygiumcumini) can inhibit xanthine oxidase using in vitro analysis.

In search of anti-inflammatory compounds, novel scaffolds containing isonicotinoyl motif were synthesized via an efficient strategy. The compounds were screened for their in vitro anti-inflammatory activity. Remarkably high activities were observed for isonicotinates 5–6 and 8a–8b. The compound 5 exhibits an exceptional IC50 value (1.42 ± 0.1 µg/mL) with 95.9% inhibition at 25 µg/mL, which is eight folds better than the standard drug ibuprofen (11.2 ± 1.9 µg/mL). To gain an insight into the mode of action of anti-inflammatory compounds, molecular docking studies were also performed. Decisively, further development and fine tuning of these isonicotinates based scaffolds for the treatment of various aberrations is still a wide-open field of research.
