为了寻找镇咳平喘药物，对野罂粟葫果进行了研究，从中分得20个生物碱单体。作者主要报道提取分离及5个微量生物碱的鉴定。经理化常数及波谱分析分别鉴定为刺罂粟碱（Ⅰ_a）、海罂粟胺（Ⅰ_c）、丽春花宁（Ⅰ_d）、丽春花定（Ⅰ_e）、和乙基丽春花宁（Ⅰ_z）。

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( I_a),glaucamine( I_c),rhoeagenine(I_d),rhoeadine( I_e)and ethylrhoeagenine( I_z).They were all isolated for the first time from this species.
