Abstract:
Objective: To study the chemical constituents in the stems of Zhuang Medicine Alsophila spinulosa. Methods: The chemical constituents were isolated and purified by silica gel, polyamide, and Sephadex LH-20 column chromatography. Their structures were elucidated by physicochemical properties and spectral analyses. Results: Sixteen compounds were isolated from the 50% and 95% ethanol extracts and identified as 30-O-β-D-xylopyranosyl-dryocrassol (1), pimaric acid (2), 9α-hydroxy-1β-methoxycaryolanol (3), 6β-hydroxy-24-ethyl-cholest-4-en-3-one (4), 1-O-hexadecanolenin (5), clovandiol (6), decumbic acid (7), n-tetracosane (8), 4-O-β-D-glucopyranosyl-p-coumaric acid (9), (E)-4-O-β-D-glucopyranosyl caffeic acid (10), cyathenosin A (11), protocatechualdehyde (12), protocatechuic acid (13), stigmastane-3, 6-dione (14), β-sitosterol (15), and daucosterol (16). Conclusion: Compound 1 is a new compound named alspineoside A, and compounds 2-11 are isolated from the stems of A. spinulosa for the first time.
