摘　　要：从丁座草[Xylanche himalaica(Hook.f.et Thoms.)G.Beck]的块茎中分离鉴定了6种化合物:3-表-乙酰熊果醛(Ⅰ)、熊果酸(Ⅱ)、3-表-熊果酸(Ⅲ)、(+)-松脂素(Ⅳ)、(+)-松脂素单葡萄糖甙(Ⅴ)和胡萝卜甙(Ⅵ)。其中,Ⅰ为新化合物。Six compounds were isolated from the tuber of Xylanche himalaica (Hook. f. et Thorns.) G. Beck. Based on the physico-chemical constants, spectral analysis (IR, MS, ~1H-NMR, ^(13)C-NMR) and preparation of the derivative, they were identified as 3-epi-acetoxyurs-12-en-28-al (Ⅰ), ursolic acid (Ⅱ), 3-epi-ursolic acid (Ⅲ), ( + )-pinoresinol (Ⅳ), ( + )-pinoresinol monoglucoside (Ⅴ) and daucosterol (Ⅵ), I is a new compound.
