Object An attempt to study, for the first time, on the chemical constituents of the husk of Xanthoceras sorbifolia Bge .. Methods The husk was extracted with ethyl acetate-water,separated on silica column, and structurally elucidated by spectral analysis (IR, MS, 1HNMR,and 13CNMR, DEPT). Results 2 st erols were identified as (3 β,5 α,20 R,24 S)-stigmasta-7,trans-22-dien-3-ol (Ⅰ) and (3 β, 5 α, 20 R<.i>, 24 S)-stigma sta-7-en-3-ol (Ⅱ). Conclusion This is the first time to r epo rt the presence of the 2 sterols in this plant.
