Abstract
AbstractThe 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 3β‐hydroxystigmast‐5‐en‐7‐one), seven triterpenoids (friedelin, lupeol, betulinaldehyde, 3β‐acetoxyurs‐11‐en‐13,28‐olide, 3β‐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).
