红景天植物在西方世界被用作自然疗法，在中国被用作传统草药，因其增强人类对压力或疲劳的抵抗力和延年益寿的能力而受到重视。由于不同种间形态相似，属的鉴定存在一定争议，可能影响其临床使用的安全性和有效性。本文从中国13个省采集了7种红景天标本47份。根据它们的形态特征、遗传和植物化学分类进行了鉴定。采用HPLC-DAD/UV方法，测定了4个化学类（苯丙类、苯乙醇衍生物、黄酮类和酚酸类）的8个生物活性化学分类标记，以评价和区分红景天样品的化学分类。采用层次聚类分析（HCA）和主成分分析（PCA）对遗传分类和植物化学分类两种分类方法进行了比较。建立的化学分类方法可有效地用于红景天的种类鉴定。
Rhodiola plants are used as a natural remedy in the western world and as a traditional herbal medicine in China, and are valued for their ability to enhance human resistance to stress or fatigue and to promote longevity. Due to the morphological similarities among different species, the identification of the genus remains somewhat controversial, which may affect their safety and effectiveness in clinical use. In this paper, 47 Rhodiola samples of seven species were collected from thirteen local provinces of China. They were identified by their morphological characteristics and genetic and phytochemical taxonomies. Eight bioactive chemotaxonomic markers from four chemical classes (phenylpropanoids, phenylethanol derivatives, flavonoids and phenolic acids) were determined to evaluate and distinguish the chemotaxonomy of Rhodiola samples using an HPLC-DAD/UV method. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to compare the two classification methods between genetic and phytochemical taxonomy. The established chemotaxonomic classification could be effectively used for Rhodiola species identification.
