Crotolaria ramosissima is a weed plant belonging to the family Leguminoseae. It is a much branched sticky woody herb. The flowers are yellow tinged with purple. It is distributed in some places of Tamilnadu and coastal areas of Andrha Pradesh. The plant contains waxes, and, when flowering, a yellow exudate appears in the inflorescences. Recently, we published the corrected structure of crotaram...

Major rooibos flavonoids--dihydrochalcones, aspalathin and nothofagin, flavones--orientin and vitexin, and a flavonol, rutin, were investigated to determine their influence on the activity of adrenal steroidogenic enzymes, 3β-hydroxysteroid dehydrogenase (3βHSD2) and cytochrome P450 (P450) enzymes, P450 17α-hydroxylase/17,20-lyase (CYP17A1), P450 21-hydroxylase (CYP21A2) and P450 11β-hydroxylas...

The structures and energetics of two dihydrochalcones (phloretin and its glycoside phlorizin) were examined with density functional theory, using the B3LYP, M06-2X, and LC-ω PBE functionals with both the 6-311G(d,p) and 6-311 + G(d,p) basis sets. Properties connected to antioxidant activity, i.e., bond dissociation enthalpies (BDEs) for OH groups and ionization potentials (IPs), were computed i...

In order to optimize conditions for the extraction of polyphenols from apples, peel and flesh of apples were subjected to an extraction process with different solvents consisting of various ratios of methanol and water (40, 60, 80 %), 100 % methanol, or with methanol acidified with hydrochloric acid (0.1 %). Extractions were performed using an ultrasonic bath with time periods from 5 to 15 min....
