摘 要:目的:研究多棘海盘车正丁醇萃取部位的化学成分。方法:利用溶媒萃取和多种色谱法,对多棘海盘车的正丁醇萃取部位化学成分进行分离,根据理化性质和现代波谱技术鉴定化合物的化学结构,并测试了其中5个化合物的生物活性。结果:分离并鉴定了5个化合物,分别为多羟基甾体皂苷amurensoside D(Ⅰ)、色氨酸(Ⅱ)和3个硫酸甾醇,包括3β-O-硫酸酯化-6α,23β-二羟基-胆甾-9(11)-23-羰基-硫酸盐(Ⅲ)、3β-O-硫酸酯化-6α-羟基-胆甾-9(11),20(22)-二双键-23-羰基-硫酸盐(Ⅳ)和3β-O-硫酸酯化-6α-羟基-麦角甾-9(11)-双键-23-羰基-硫酸盐(Ⅴ)。结论:化合物Ⅱ是首次从多棘海盘车中得到,化合物Ⅲ和Ⅴ对稻瘟霉菌P-2b显示较强的药理活性。Objective: To investigate the chemical constituents in the BuOH extract of Asterias arnurensis. Methods: The compounds were obtained by a combination of extraction and purification with suitable solvent and multiple column chromatographies; their structures were determined based on spectral analysis and physicochemical properties. The hioactivities of 5 compounds were tested. Results: Five compounds were isolated and identified, and they were amurensoside D ( Ⅰ ), tryptophan Ⅱ , and 3 sulfated sterols, including 3β-O-sulfated-6α, 20β-diol-cholest-9 ( 11 ) en-23-one sodium salt ( Ⅲ ), 3β-O- sulfated-6α-ol-cholesta-9 ( 11 ), 20 ( 22 )-dien-23-one sodium salt ( Ⅳ ), and 3β-0-sulfated-6α-ol-ergost 9 ( 11 )-en-23-one sodium salt (Ⅴ). Conclusion: TryptophanⅡ is obtained from this species for the first time; compoud Ⅲ and compound V exhibit potent inhibitory activity against Pyricularia oryzae P 2b.
