The properties of Mon Thong, Chani and Kan Yao durian (Durio zibethinus Murr.) cultivars were compared in vitro and in vivo studies in order to find the best one as a supplement to antiatherosclerotic diet. Total polyphenols (361.4+/-35.3 mgGAE/100g FW), flavonoids (93.9+/-8.9 mgCE/100g FW) and total antioxidant capacity determined by DPPH and beta-carotene-linoleic acid assays (261.3+/-25.3 mi...
متن کاملAnalysis of translocatory balance in durian (Durio zibethinus) fruit.
We estimated translocatory balance in fruit of the tropical tree Durio zibethinus Murray on the basis of a compartment model. Rates of fruit respiration, dry weight growth and translocation increased with time. Over the 8.2 weeks of fruit development, the relative distribution of translocation was 80% to dry weight growth and 20% to respiration. The ratio of respiration rate to translocation ra...

The scientific basis of the adverse, or at times lethal, effect of ingesting durian (Durio zibethinus Murray) while imbibing alcohol has not been established. Symptoms are reminiscent of the Disulfiram-Ethanol Reaction (DER) arising from the inhibition of aldehyde dehydrogenase (ALDH). Cognizant of the inhibitory effect of sulfur compounds like disulfiram on ALDH and the rich sulfur content of ...
