التحليل الكروماتوغرافي-الكتلي لبعض المركبات الفعالة حيويا في اثنين من النباتات الطبية اليمنية

Medicinal plants have a broad range of bioactive substances due to the secondary metabolite compositions and used in treatment of several diseases. This study aimed at investigating the methanolic extraction of the bioactive compounds in two Yemeni medicinal plants (Dorstenia foetida and Lavandula pubescens Decne) using high-performance liquid chromatography-mass spectrometry. The proposed method provided a tentative identification of several constituents such as alkaloids, flavonoid, steroids, terpenoids and coumarin in the studied plants.
