甜叶菊Stevia rebaudiana是一种应用广泛的菊科植物，具有降血糖、抗肿瘤、抗氧化、抗炎、降血压、调血脂等多种药理作用，其化学成分主要包括二萜类、黄酮类、多酚类、多糖等。基于甜叶菊化学成分和药理作用的研究进展，从植物亲缘性和化学成分特有性、成分可测性、成分有效性及传统药性等方面对甜叶菊质量标志物（quality marker，Q-Marker）进行预测分析，初步预测甜菊苷、莱鲍迪苷A、莱鲍迪苷C、黄酮苷、绿原酸等可作为甜叶菊的主要Q-Marker，为完善甜叶菊质量评价体系提供参考。

Tianyeju (Stevia rebaudiana) is a widely used plant of Asteraceae family, with various pharmacological effects such as hypoglycemic, antitumor, antioxidant, anti-inflammatory, hypotensive, and lipid-regulating effects, etc. Its chemical composition mainly includes diterpenes, flavonoids, polyphenols, and polysaccharides. Based on the research progress of chemical composition and pharmacological effects of S. rebaudiana, the quality marker (Q-Marker) of S. rebaudiana was predicted and analyzed from the aspects of plant affinity and chemical composition specificity, component measurability, component validity and traditional medicinal properties. The preliminary prediction was that stevioside, rebaudioside A, rebaudioside C, flavonoid glycosides and chlorogenic acid could be used as the main Q-Marker of S. rebaudiana, which would provide reference for improving the quality evaluation system of S. rebaudiana.
