一般描述
β-Amyrin是一种自然存在的五环三萜类化合物，具有抗炎、抗微生物、抗氧化和化学保护等特性。
应用
该分析标准物也适用于以下应用：
- 开发并验证两种高效薄层色谱（HPTLC）法，以测定G. senegalensis叶子乙醇提取物中四种生物标志物的含量，即s— β-香树脂醇、 β-谷甾醇、羽扇豆醇和熊果酸
- 采用新型HPTLC密度测试法分析五种榕树叶片样品的甲醇提取物，以便测定β-香树脂醇的含量，该方法已根据国际协调会议（ICH）指南得到验证
- 采用经过验证的高效薄层色谱（HPTLC）密度法，对两种Maytenus物种，M. obscura和M. parviflor的乙醇提取物中的香树脂醇β进行定量分析
- 采用气相色谱-质谱联用（GC-MS）和高效液相色谱（HPLC）技术对21种不同大麻品种的82种植物的不同部位进行次生代谢物分析，以测定甾醇和单、倍半、三倍萜类化合物的含量，并采用紫外线和质谱（MS）检测来分析黄酮类化合物

Polyploid plants are more often invasive species than their diploid counterparts. As the invasiveness of a species is often linked to its production of allelopathic compounds, we hypothesize that differences in invasive ability between cytotypes may be due to their

Plants prevent dehydration by coating their aerial, primary organs with waxes. Wax compositions frequently differ between species, organs, and developmental stages, probably to balance limiting nonstomatal water loss with various other ecophysiological roles of surface waxes. To establish structure-function relationships
