目的研究山矾Symplocos caudata的化学成分。方法采用色谱法分离,用波谱方法进行结构鉴定。结果从山矾根中分离鉴定了9个化合物,5个木脂素苷:(7R,8S)-二氢脱氢二松柏醇4-O-β-D-呋喃芹糖基-(1→6)-O-β-D-吡喃葡萄糖苷(Ⅰ)、(7S,8R)-二氢脱氢二松柏醇4-O-β-D-吡喃葡萄糖苷(Ⅱ)、(7R,8S)-二氢脱氢二松柏醇9′-O-β-D-吡喃葡萄糖苷(Ⅲ)、橙皮素B(Ⅳ)、(+)-落叶松脂素-O-β-D-吡喃葡萄糖苷(Ⅴ);还有1个三萜,2个甾醇和1个芳香苷:白桦脂酸(Ⅵ)、Δ7-豆甾烯醇(Ⅶ)、菠甾醇(Ⅷ)和3,4,5-三甲氧基苯基-1-O-β-D-呋喃芹糖基-(1→6)-O-β-D-吡喃葡萄糖苷(Ⅸ)。结论除化合物Ⅰ和Ⅸ外,其他化合物均为首次从山矾科植物中分离得到。
Objective To study the chemical constituents of Symplocos caudata. Methods Chromatography was used to identify the structure of the spectrum. Results Nine compounds were isolated and identified from the roots of peanut. Five lignan glucosides were identified as (7R, 8S) -dihydrogenated diosgenin 4-O-β-D-furanosyl- (1 → 6 ) -D-glucopyranoside (I), (7S, 8R) -dihydrodeboydisone 4-O-β-D-glucopyranoside (II), (7R, 8S) - dihydrodehydorticepsin 9’-O-β-D-glucopyranoside (III), hesperetin B (Ⅳ), (+) - larchinone-O- β -D- glucopyranose Glycosides (Ⅴ); there is also one triterpenoid, two sterols and one alucoside: betulinic acid (Ⅵ), Δ7-stigmasterol (Ⅶ), spinostat (Ⅷ) and 3,4,5- Trimethoxyphenyl-1-O-β-D-furanosyl- (1 → 6) -O-β-D-glucopyranoside (IX) Conclusion All the compounds except for compounds I and IX were isolated from the plants of the genus Araceae for the first time.
