The ecology and quinolizidine alkaloid chemistry of Calia secundiflora (Ortega) Yakovlev growing at two sites in Mexico were compared. At one site (Hidalgo) the vegetation was dominated by Flourensia resinosa and C. secundiflora, at the other site (Queretaro) C. secundiflora and Dodanaea viscosa were dominant. The Hidalgo site had shallower soils with less organic matter, N, P, and CaCO3. Seeds of C. secundiflora from each site accumulated a similar range of quinolizidine alkaloids, but the profile of alkaloids in the leaves and roots were different. The leaves and roots of plants at Hidalgo accumulated a similar range of alkaloids to the seeds with cytisine and/or N-methylcytisine being most abundant, whereas at Queretaro the leaves and roots accumulated lupinine, with other alkaloids being relatively minor constituents. The latter profile has not been reported previously for C. secundiflora.
对生长在墨西哥两个地点的次生花菱草（Calia secundiflora (Ortega) Yakovlev）的生态学和喹诺里西啶生物碱化学进行了比较。在一个地点（伊达尔戈），植被以树脂弗洛伦斯菊（Flourensia resinosa）和次生花菱草为主；在另一个地点（克雷塔罗），次生花菱草和粘毛豆科（Dodanaea viscosa）占主导地位。伊达尔戈的土壤较浅，有机质、氮、磷和碳酸钙含量较低。来自每个地点的次生花菱草种子积累了相似范围的喹诺里西啶生物碱，但叶片和根部的生物碱谱不同。伊达尔戈的植物叶片和根部积累的生物碱范围与种子相似，其中金雀花碱和/或N-甲基金雀花碱含量最高，而在克雷塔罗，叶片和根部积累的是羽扇豆碱，其他生物碱是相对次要的成分。次生花菱草的后一种谱此前未见报道。
