LI Yun-xiang et al(Institute of Sericulture,Chengde Medical College, Chengde,Hebei 067000)  
[Objective] The purpose was to study the yield constituents of Papaver nudicaule L.[Method] The fresh and dry weights per plant of wild P.nudicaule,1 and 2 years old ones planted artificially on Chengde dam were investigated and the contents of total alkaloid and papaverine in different parts of plant were determined to sum up the yield constituents of P.nudicaule.[Result] The difference in dry weight per plant of wild P.nudicaule was bigger and its dry yield was 1 650.0 kg/hm2.The wet yields of 1 and 2 years old P.nudicaule were 9 354.0 and 11 638.5 kg/hm2 resp.and their dry yields were 1 402.5 and 2 034.0 kg/hm2 resp.The distribution order of total alkaloid and papaverine in various parts of P.nudicaule plant was shell seed flower leaf flower stem root,but their contents had significant difference.Late July to early Sep.was the period when the contents of total alkaloid and papaverine in P.nudicaule plant were highest.[Conclusion] The direct constituents of P.nudicaule yield were yield per plant and plants per unit area and its indirect constituents were different harvest periods and positions.
