对浙江省４种雀梅不同部位有效成分分析表明：雀梅所含的生物碱以大麦碱为主；雀梅中的总生物碱含量以及大麦碱含量均以刺藤子为最高，以钩刺雀梅藤为最低。它们的含量次序都是刺藤子、雀梅藤、梗花雀梅藤和钩刺雀梅藤，而且种间差异极显著。４种雀梅所含大麦碱和其他生物碱都主要存在于地下部分，其中须根中含量最高，主根中次之，而地上部分所含的量很少。经检验，地下部分与地上部分两者间也存在着极显著差异。
The results showed that the alkaloids contained in the spruce plum were mainly barley alkaloids. The total alkaloid content and the content of barley in Capreola were highest in spines of rattan, Maitreya is the lowest. The order of their contents is rattan, capitatum, stems, sparrows and plum rattan, and the interspecific differences are extremely significant. Four kinds of plum contained barley alkaloids and other alkaloids are mainly found in the underground part, including the highest content in the fibrous roots, followed by the main roots, and the aerial parts contained in small amounts.
