STUDIES ON CHEMICAL CONSTITUENTS OF RHODIOLA PHARIENSIS (H. OHLA) S. H. FU
【摘要】 从帕里红景天[Rhodiola phariensis(H. Ohla) S. H. Fu]根茎的石油醚和乙醇提取部分共分得14 种结晶性化合物,经光谱分析和化学反应,分别鉴定为二十二(烷)醇(1-docosanol,Ⅰ)、二十六(烷)酸(cerotic acid, Ⅱ)、十九(烷)醇(1-nonadecanol, Ⅲ)、β-谷甾醇(β-sitosterol,Ⅳ)、二十七(烷)醇(1-heptacosanol, Ⅴ)、红景天甙(salidroside, Ⅵ)、麦芽糖(m altose, Ⅶ)、棉皮素-8-葡萄糖甙(gossypin, Ⅷ)、胡萝卜甙(daucosterol, Ⅸ)、酪醇(tyrosol, Ⅺ)、咖啡酸(caffeicacid, Ⅻ)、没食子酸(gallic acid, 珎珋珋珋)、伞形花内酯(um belliferone, 珎珋珌)和新化合物帕里甙(pharienside, Ⅹ)
【Abstract】 Rhodiola phariensis (H. Ohla) S. H. Fu is native to China. This species is distributed in Xizang of China. So far no datum of its chemical constituents has been recorded. Fourteen crystalline substances were isolated from the petroleum ether and ethanol extractions of the rhizome of this plant. Thirteen of them were identified as 1 docosanol, cerotic acid, 1 nonadecanol , β sitosterol, 1 hepacosanol, salidroside, maltose, gossypin, daucosterol, tyrosol, caffeic acid, gallic acid, umbelliferone by chemical and spectral (IR, 1H NMR, 13 C NMR, and MS) analysis. Ⅹ was a new compound named pharienside. It’s structure was elucidated as p O galloy salidroside by IR, 1H NMR, 13 C NMR, MS and chemical reactions. Gossypin was obtained from the genus Rhodiola L. for the first time.
