The Chemical Constituents from the Bulbs of Ornithogalum caudatum

Abstract

Abstract: A new natural product (1) together with 26 know compounds were isolated from the Bulbs of Ornithogalum caudatum. Their structures were established on the basis of spectral analyses as n-butyl pyroglutamate (1), nonadecyl alcohol(2), eicosanol(3), behenic acid(4), β-sitosterol(5), stigmasterol(6), glycerol 1-monocerotate(7), pyrocatechol(8), p-ethoxybenzoic acid(9), p-coumarinic acid(10), protocatechuric acid(11), ursolic acid(12), betulinic acid(13), fumaric acid(14), succinic acid(15), uracil(16), xanthine(17), quercetin(18), kaempferol (19), isorham-netin(20), adenosine(21), daucosterol(22), stigmasterol 3-O-β-D-glucopyranoside(23), quercetin 3-O-β-D-glucopyra-noside(24), kaempferol 3-O-β-D-glucopyranoside(25), rutin(26), and kaempferol 3-O-β-rutinoside(27). All of them, except compound 5, were isolated from this plant for the first time.
