To investigate the antidepressant components of Polygala tenuifolia.
The chromatographic method was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis, MTT method was applied to investigate their cytotoxic activities.
Nine compounds were isolated from the roots of P. tenuifolia. Their structures were identified as sibiricose A, (1), sibiricose A5 (2), tenuifoliside A (3) and 3', 6-disinapoyl sucrose (4), sibiricose A6 (5), 3, 4, 5-trimethoxycinnamate (6), polygalaxanthone III (7), tenuifolioses A (8), tenuifolioses H (9) and some compounds' activities to PC12 were observed.
Compound 1 was isolated from this plant for the first time. Compounds 2,3 could protect PC12 cells damage induced by P. tenuifolia.
研究远志的抗抑郁成分。
采用色谱法分离纯化化学成分，通过光谱分析鉴定其结构，运用MTT法研究其细胞毒性活性。
从远志根中分离出9种化合物。其结构鉴定为西伯利亚远志糖A，（1），西伯利亚远志糖A5（2），细叶远志皂苷A（3）和3'，6-二芥子酰蔗糖（4），西伯利亚远志糖A6（5），3，4，5-三甲氧基肉桂酸（6），多花远志酮III（7），细叶远志糖A（8），细叶远志糖H（9），并观察到部分化合物对PC12细胞的活性。
化合物1首次从该植物中分离得到。化合物2、3可保护PC12细胞免受远志诱导的损伤。
