Background: Bauhinia winitii (BW) (Fabaceae) plant revealed poor phytochemical investigation and anti-diabetic report. As one of the family which known with abundant flavonoids content, contrary, BW was only used for treatment diarrhea in Thai conservative remedy. Objectives: The aim this study to investigate constituents anti-alpha glucosidase activity BW. Materials Methods: Phytochemical base...

a new method for the synthesis of water soluble polyaniline (pani) using hemin chloride (h.c) in the presence of hydrogen peroxide (h.p) is presented. hemin chloride is an effective catalyst for the oxidative polymerization of aniline in the presence of hydrogen peroxide at room temperature. the uv- vis absorption spectra of the product show a distinct absorption peak at 430 nm in ph 4.0 b...

There is an urgent need for new substances to overcome current challenges in the health sciences. Marine fungi are known producers of numerous compounds, but manipulation growth conditions optimal compound production can be laborious and time-consuming. In Portugal, despite its very long coastline, there only a few studies on marine fungi. From collection Portuguese fungi, we screened antimicro...

Luciferase activity in cell-free extracts of the bioluminescent marine dinoflagellate Gonyaulax polyedra undergoes a cyclic daily change such that activities of extracts made in the middle of the night phase may be 10 times greater than in extracts of day phase cells. These cyclic changes continue under constant conditions, in a manner indicative of control by an endogenous circadian cellular m...

The enzymatic conversion of xanthoxin to abscisic acid by cell-free extracts of Phaseolus vulgaris L. leaves has been found to be a two-step reaction catalyzed by two different enzymes. Xanthoxin was first converted to abscisic aldehyde followed by conversion of the latter to abscisic acid. The enzyme activity catalyzing the synthesis of abscisic aldehyde from xanthoxin (xanthoxin oxidase) was ...
