dioclea glabra/抗氧化劑

Dioclins A (1) and B (2), the new flavonoids, have been isolated from the ethyl acetate soluble fraction of the roots of Dioclea reflexa along with 3,5-dihydroxy-4 methoxybenzoic acid (3), lupeol (4) and the rare dipeptide, auratiamide acetate (5). Their structures have been elucidated by

The A-type proanthocyanidin, epigallocatechin-(2beta-->7,4beta-->8)-epicatechin, together with the known epicatechin, luteolin 3'beta-D-glucopyranoside, chrysoeriol 7beta-D-glucopyranoside and 2-methylpentan-2,4-diol, were isolated from leaves of Dioclea lasiophilla. The structures were established

Dioclea reflexa bioactive compounds have been shown to contain antioxidant properties. The extracts from the same plant are used in traditional medical practices to treat various diseases with impressive outcomes. In this study, ionic mobility in Saccharomyces cerevisiae cells in the

BACKGROUND Since the beginning of civilization, herbal medicines have been an important source for human beings to treat their ailments. Despite the large number of synthetic remedies available in the market, the use of plants is seen as a great challenge in the search for new substances endowed

The antioxidant activity of floranol (3,5,7,2'-tetrahydroxy-6-methoxy-8-prenylflavanone), a new flavonoid isolated from the roots of Dioclea grandiflora, was evaluated by the inhibition of human low-density lipoprotein (LDL) oxidation. Floranol increased its oxidation lag-phase significantly in a
