【Abstract】 In an attempt to find better antitussive and antiasthmatic drugs,the chemical constituent of capsule of Papaver nudicaule L. was studied. As a result twenty alkaloids were obtained. The procedure of isolation,separation and the identification of 5 of the minor alkaloids were reported presently. On the basis of physical and chemical properties and spectral analysis,they were identified as stylopine (Ⅰa ),glaucamine (Ⅰc),rhoeagenine (Ⅰd),rhoeadine(Ⅰe.)and ethylrhoeagenine(Ⅰz). They were all isolated for the first time from this species更多还原
