OBJECTIVE
To study the lignans from the whole plant of Gentianella acuta.
METHODS
The compounds were isolated by various chromatographic techniques and indentified by spectroscopic methods.
RESULTS
Nine compounds were isolated and identified as (7R,8S) -dehydrodiconiferyl alcohol-4,9'-O-beta-D-glucopyranoside (1), alaschanisoside A (2), citrusin A (3), olivil-4'-O-beta-D-glucopyranoside (4), leptolepisol D (5), acanthoside D (6), (+) pinoresinol-4-O-beta-D-glucopyranoside (7), (+) 8-hydroxypinoresinol-4-O-beta-D-glucopyranoside (8), and (+) pinoresinol-8-O-beta-D-glucopyranoside (9).
CONCLUSION
Compounds 1 - 9 are isolated from this plant for the first time, compounds 1 and 9 are isolated from Gentianella genus for the first time,and compounds 2, 3 and 5 - 8 are isolated from Gentianaceae family for the first time.
目的
研究尖叶假龙胆全草中的木脂素。
方法
采用多种色谱技术分离化合物，并通过光谱方法进行鉴定。
结果
分离并鉴定出9种化合物，分别为(7R,8S)-脱氢二松柏醇-4,9'-O-β-D-吡喃葡萄糖苷(1)、阿拉善苷A(2)、柑橘苷A(3)、橄榄脂素-4'-O-β-D-吡喃葡萄糖苷(4)、细叶假龙胆醇D(5)、刺五加苷D(6)、(+)松脂醇-4-O-β-D-吡喃葡萄糖苷(7)、(+)8-羟基松脂醇-4-O-β-D-吡喃葡萄糖苷(8)和(+)松脂醇-8-O-β-D-吡喃葡萄糖苷(9)。
结论
化合物1 - 9首次从该植物中分离得到，化合物1和9首次从假龙胆属植物中分离得到，化合物2、3和5 - 8首次从龙胆科植物中分离得到。
