This study was aimed at determining the phytochemical composition, antioxidant effect and acute toxicity of Irvingia gabonensis (O'Rorke) baill (IG) ethanolic leaf extract. Qualitative phytochemcal analysis was carried out on the ethanolic leaf extract using standard procedures. Different concentrations of the plant extract (20 µg/ml-100µg/ml) were used to assess its effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical activity, It's reducing power and it total phenolic content. Lorke's method of acute toxicity was adopted for the acute toxicity study. Results obtained showed the presence of saponins, tannins, flavonoids, cardiac glycosides, steroids, and carbohydrates in the leaf extract. The ethanolic leaf extract of IG significantly (P< 0.05) inhibited the activity of DPPH when compared with the vitamin C standard. IG leaf extract also showed a higher reducing power as compared with the Vitamin C standard. The total phenolic content of IG ethanolic leaf extract was however, significantly (P<0.05) lower than that of gallic acid, the standard used. Futhermore, the LD50 of the ethanolic leaf extract was found to be above 5000mg/kg body weight. Irvingia gabonensis (O'Rorke) baill ethanolic leaf extract is a rich source of important phytochemicals and possesses a high antioxidant activity. Also, the administration of the ethanolic leaf extract in wistar rats is safe up to a dose of 5000mg/kg body weight.

Background: Cuscuta reflexa (C. reflexa) is a parasitic climber of medicinal importance. The present study was aimed to evaluate the nutraceutical potential of C. reflexa stems collected from different hosts and to evaluate the role of the herbal formulation in dandruff, hair fall control as well as hair growth promoter. Materials and Methods:Hair formulations of C. reflexa collected from different host plants were prepared in the form of herbal oils (10% w/v). C. reflexa stems were extracted using mustard oil as base oil by using direct boiling technique. Prepared oil was studied as hair tonic. The experimental protocols used were anti-dandruff hair growth activity, as well as hair fall reduction. Herbal hair oils versus mustard oil were evaluated by applying oils on human volunteers with hair fall and dandruff problem whereas promotion of hair growth activity was conducted on rats. The formulated oils were also characterised for proximate analysis, physiochemical composition, as well as antimicrobial activity. Result: The test oils of C. reflexa collected from Azadiracta indica and Zizyphus jujuba were effective in the promotion of hair growth, dandruff control, as well as reduction in hair fall activity. Conclusion: All the formulated oils showed potent antimicrobial activity against all selected strains of bacteria and fungi.

Ethanol extract of the stem bark of Streblus asper Lour was considered for qualitative assessment for its secondary metabolites content like alkaloids, glycosides, sterols and others. Bark extract revealed anticarcenogenic i.e. antimitotic, cytotoxic and antitumor activities. Results of different anticarcenogenic activities of the bark extract were discussed in relation to its secondary metabolite contents.
