- 中文摘要: The isolation and identification of fifteen compounds from the heartwood of Diospyros eriantha are described. Their structures were determined on the basis of spectral evidence and/or comparison with authentic samples. These compounds include three steroids (stigmast-4-en-3-one, stigmast-4-ene-3,6-dione, and 3.beta.-hydroxystigmast-5-en- 7-one), seven triterpenoids (friedelin, lupeol, betulinaldehyde, 3.beta.-acetoxyurs-11-en-13,28-olide, 3.beta.-acetoxyoleanolic acid, betulin, and betulinic acid), three quinones (2-ethoxy-7-methyljuglone, 3-ethoxy-7- methyljuglone, and 2,6-dimethoxy-1,4-benzoquinone), and two phenols (3,4,5-trimethoxyphenol, and syringic acid).
