中药土槿皮是松科(Pinaceae)植物金钱松(Pseudolarix Kaempferi Gor-don)的干燥树皮及根皮。过去对土槿皮原药抗真菌作用已有不少研究,其化学成份也有人进行了分析,并从原药中提取了土槿皮乙酸,报告了它的分子式,为C_(23)H_(28)O_8,展开式为C_(15)H_(12)O(C=C—COOH)(COOCH_3)(OCO-CH_3)(C=O),进一步测定和解析了土槿皮乙酸的高分辨质谱,提出土槿皮乙酸可
The Chinese herbaceous soil is the dry bark and root bark of the Pinaceae plant Pseudolarix Kaempferi Gor-don. In the past, there have been many studies on the antifungal effects of the raw materials of Smilax glabra. Some chemical constituents have also been analyzed. Stilbene acetic acid has been extracted from the original drug and its molecular formula has been reported as C_(23)H_ ( 28) O_8, the expansion formula is C_(15)H_(12)O(C=C—COOH)(COOCH_3)(OCO-CH_3)(C=O), and further determination and analysis of high resolution mass spectrometry of soil acetic acid , raised soil acetic acid
