掌叶半夏化学成分的研究(Ⅴ)
Studies on the Chemical Constituents of Pedate Pinellia (Pinellia pedatisecta)
【摘要】 从天南星科植物掌叶半夏PinelliaPedatisecta块茎的生物碱部分,分离鉴定了7个化合物:L-脯氨酰-L-丙氨酸酐(L-prolyl-L-alanineanhydride,ⅩⅩⅤ),3-乙酰胺基-2-哌淀酮(3-acetamino-2-piperidone,ⅩⅩⅥ),腺苷(adenosine,ⅩⅩⅦ),L-苯丙氨酰-L-丝氨酸酐(L-phenylalanyl-L-serylanhydride,ⅩⅩⅧ),L-酪氨酰-L-丙氨酸酐(L-tyrosyl-L-alanineanhydride,ⅩⅩⅨ),掌叶半夏碱丁(pedatisectineD,ⅩⅩⅩ),掌叶半夏碱戊(pedatisectineE,ⅩⅩⅩⅠ),均为首次从该植物中分得,其中掌叶半夏碱丁、戊为2个吡嗪类新化合物。
【Abstract】 From the alkaloid extraction of rhizoma of Pinellia pedatisecta schott, seven compounds werc isolated and identified by chemical and spectroscopic methods. They are L-prolyl -Lalanine anhydride (ⅩⅩⅤ), 3-acetamino-2-piperidone (ⅩⅩⅥ), adenosine (ⅩⅩⅦ), Lphenylalanyl-L-seryl anhydride (ⅩⅩⅧ), L-tyrosyl-L alanine anhydride (ⅩⅩⅨ), pedatisectine D (ⅩⅩⅩ), pedatisectine E (ⅩⅩⅩⅠ). All above compounds were obtained from this plant for the first time, among which ⅩⅩⅩ and ⅩⅩⅩⅠ are new compounds.
