Abstract:
The column chromatography on silica gel, sephadex LH-20 preparative HPLC were used to separate and purify the compounds from the stems of Dendrobium candidum. Twenty compounds were isolated and identified as 3,4'-dihydroxy-5-methoxybibenzyl(1), dihydroresveratrol(2), dendromoniliside E(3), denbinobin(4),2,4,7-trihydroxy-9, 10-dihydrophenanthrene(5), aduncin(6), (-)-loliolide(7), adenosine(8), uridine(9), guanosine(10), sucrose(11), 5-hydroxymethyl-furaldehyde(12), n-octacostyl ferulate(13), defuscin(14), n-triacontyl cis-p-coumarate(15), daucosterol(16), beta-sitosterol(17), hexadecanoic acid(18), hentriacontane(19), and heptadecanoic acid(20). Their structures were elucidated on the basis of spectroscopic data and physicochemical properties. All of the compounds were isolated from this plant for the first time.
