华南马尾杉的主要成分是生物碱,它有显著的可逆性胆碱酯酶抑制作用。从华南马尾杉Phlegmariurus fordii(Baker)得四个生物碱,其中二个为已知生物碱马尾杉碱甲(phlegmariurine A)和马尾杉碱乙(phlegmariurine B)另外二个为新生物碱Ⅰ(C_(32)H_(44)N_2O_4)和Ⅱ(C_(16)H_(20)N_2O),分别定名为马尾杉碱丙(phlegmariurine C)和福地明(fordimine)。马尾杉碱丙是马尾杉碱甲的双分子化合物,根据高分辨质谱,提出了它的裂解方式,并探讨了双分子化合物的连接点。
The main component of South China’s Taxus is alkaloids, which have significant reversible cholinesterase inhibition. Four alkaloids were obtained from Phagemariurus fordii (Baker) from South China, two of which are the known alkaloids phlegmariurine A and phlegmariurine B. The other two are new alkaloids I (C_ (32) H_(44)N_2O_4) and II(C_(16)H_(20)N_2O) were named phlegmariurine C and forimine, respectively. Hydrobromide is a bimolecular compound of carnitine A. Based on high-resolution mass spectrometry, its cleavage method was proposed and the connection points of bimolecular compounds were explored.
