春季和秋季莓叶委陵菜叶片和地下部分芦丁及儿茶素含量的HPLC分析

Contents of rutin and catechin in leaves and under-ground part of Potentilla fragarioides L.in spring and autumn were determined by HPLC technology.The results show that in spring,rutin content in leaves and under-ground part of P.fragarioides is 1.670 3 and 0.054 4 mg·g-1,and catechin content is 0.263 5 and 0.723 5 mg·g-1,respectively.In autumn,rutin content is 0.586 9 and 0.010 7 mg·g-1,and catechin content is 0.784 3 and 0.366 4 mg·g-1,respectively.The rutin content in leaves is the highest in spring,and catechin content in leaves is the highest in autumn.Therefore,collecting leaves in spring is suitable for taking rutin as a purpose,while collecting leaves in autumn is suitable for taking catechin as a purpose.

长柔毛委陵菜两个种群对重金属富集和热值的影响

测定了生长在云南省金顶铅锌矿的北厂和跑马坪矿段的Zn超富集植物长柔毛委陵菜野外植株的Zn、Pb、Cd等重金属含量和热值特征,并分析了重金属和热值之间的相关性。结果表明,北厂种群的叶片、叶柄和根中Zn的含量分别达到6217.05、7679.86 mg.kg-1和4455.44 mg.kg-1,分别是跑马坪种群的3.2、2.4倍和2.2倍;北厂种群叶片、叶柄和根的Cd含量分别为170.17、242.51 mg.kg-1和244.45 mg.kg-1,分别是跑马坪种群的3.0、2.2倍和1.9倍;而跑马坪种群叶片、叶柄和根的Pb含量分别达到1042.49、829.27 mg.kg-1和2621.39 mg.kg-1,分别是北厂种群的1.2、1.0倍和1.2倍;土壤中重金属含量的不同是造成两个种群富集Zn、Pb和Cd差异的原因。长柔毛委陵菜两个种群对相同重金属的转运和生物富集能力无显著差异,其中对重金属的转运能力呈现ZnCdPb的关系。同时,两个种群的叶片、叶柄和根中的灰分含量和去灰分热值都没有显著差异,其中根部的灰分含量最低,都小于6%;北厂和跑马坪种群的所有部位的热值以叶片最高,其中去灰分热值分别达到19.03kJ.g-1和19.57kJ.g-1。Fe和Mn对长柔毛委陵菜的热值累积有促进作用。
