Chemical Constituents from Syzygium malaccense
摘要
Abstract
In order to search for chemical constituents from the fruits of Syzygium malaccense,normal and adverse column chromatography(CC)as well as Sephadex LH-20 and MCI gel(CHP20P)CC wereused to isolate and purified compounds.In result,seventeen compounds were obtained and their structures were identified by the 1H NMR and 13CNMR experiments and comparison with the values reported as kaempferol-3-O-β-D-galucopyranoside(1),kaempferol-3-O-α-L-rhamnopy-ranoside(2),isorhamnetin(3),isorhamnetin-3-O-α-L-rhamnopyranoside(4),quercetin-3-O-β-D-glucopyranoside(5),quer-cetin-3-O-α-L-rhamnopyranoside(6),quercetin-3-O-β-D-xylopyranoside(7),myricetin-4'-methoxy-3-O-α-L-rham-nopyranoside(8),6,8-dimethylpinocembrin(9),pinocembrin-7-O-β-D-glucopyranoside(10),stercurensin(11),phloridzosid(12),3-O-methylellagic acid 3'-O-α-L-rhamnopyranoside(13),epimedokoreanone A(14),5,7-dihydroxy-2-methylchro-mone(15),trans-cinnamic acid(16),dimethylmalate(17).In which 10 isolates belongs to flavonoid and 2 to chalcone.Among them,compounds 4,6,14,15 and 17 were isolated from the genus Syzygium for the first time,1,4,5,6,9,10 and 13-17 were ac-quired from S.malaccense for the first time,and all of them were firstly obtained from the fruits of S.malaccense.关键词
