Chemical Constituents from the Receptacle of Nelumbo nucifera
摘要
Abstract
Objective:To study the chemical constituents of Nelumbo nucifera receptacle.Methods:The ethanol extract of Nelumbo nucifera was isolated and purified by silica gel column,ODS column,Sephadex LH-20,preparative HPLC and other techniques.The structures were identified by ESI-MS,NMR and other spectral data.Results:Sixteen compounds were isolated from Nelumbo nucifera re-ceptacle and identified as 23-hydroxy-betulinic acid-28-O-β-D-glucopyranoside(1),maesopsin-6-O-β-D-glucopyranoside(2),rhamne-tin-3-O-β-D-glucuronide-6″-methyl ester(3),(22E,24R)-ergosta-4,6,8(14),22-tetraen-3-one(4),quercetin-3-O-α-L-arabinopyrano-side(5),nelumnucifoside B(6),kaempferol-7-O-β-D-glucoside(7),isorhamnetin-3-O-β-D-glucoside(8),lysicamine(9),quercetin-3-O-β-D-glucuronide(10),hyperoside(11),kaempferol-3-O-β-D-galactoside(12),isorhamnetin-3-O-β-D-galactoside(13),syringetin-3-O-β-D-glucoside(14),isoquercitrin(15),liriodenine(16),respectively.Conclusion:Among them,compounds 1 to 4 are isolated from Nelumbo genus for the first time,and compounds 5 to 9,12,16 are isolated from Nelumbo nucifera for the first time.关键词
