Secondary metabolites in durian seeds: oligomeric proanthocyanidins.
Ethanolic extract of durian seeds was fractionated by reverse phase flash column chromatography and the fractions characterized by electrospray ionization mass spectroscopy. Among a few unknown compounds collected, oligomeric proanthocyanidins (OPCs) were found to be one of the main compounds. Based on this result, the OPCs were purified the first time from the durian seeds using standard proce...
متن کاملOligomeric proanthocyanidins from grape seeds effectively inhibit ultraviolet-induced melanogenesis of human melanocytes in vitro.
The oligomeric proanthocyanidins (OPCs) from grape seeds are expected to be novel and potent anti-oxidants that more effectively protect skin cells against oxidative stress. UV-induced oxidative stress is considered to promote melanogenesis and serious skin damage. However, the effect of OPCs on UV-induced melanogenesis is still unknown. To investigate the role of OPCs on melanogenesis of human...
متن کاملUptake of Seeds Secondary Metabolites by Virola surinamensis Seedlings
The major secondary metabolites and fatty acids occurring in the seeds of Virola surinamensis were monitored by GC-MS during germination and seedling development. The role as carbon source for seedling development was indicated considering that both classes of compounds were similarly consumed in the seeds and that no selective consumption of compounds could be detected.
متن کاملSalix daphnoides: A Screening for Oligomeric and Polymeric Proanthocyanidins.
In the present study, a qualitative analysis of proanthocyanidins (PAs) from an aqueous-methanolic extract of Salix daphnoides VILL. bark is described. Procyanidin B1 (1), B2 (2), B3 (3), B4 (4), C1 (5), epicatechin-(4β→8)-epicatechin-(4β→8)-catechin (6) and epicatechin-(4β→8)-epicatechin-(4β→8)-epicatechin-(4β→8)-catechin (7) have been isolated by a combination of different chromatographic sep...
متن کاملSUMMARY OF DATA FOR CHEMICAL SELECTION Oligomeric Proanthocyanidins from Grape Seeds and Pine Bark BASIS OF NOMINATION TO THE CSWG
Based on the structures of identified active ingredients, the phenolic compounds extracted from grape seeds and pine bark would not be expected to be genotoxic. Indeed, the inventor of pycnogenol states that this product was tested in Salmonella typhimurium and was negative. Substantial health claims for grape seed and pine bark extracts, including some studies showing tumor inhibition, make th...
