Zanthoxylum rhetsa (Roxb.) DC or Ma-khwuang (Rutaceae family) has long been used in Thai culinary and traditional medicine. Its fruits and seeds are used for anti-diabetic, antispasmodic, diuretic and anti-inflammatory activity. Based on its medicinal usage, we have evaluated the quality parameters of Z. rhetsa fruits and seeds. Ten samples of Z. rhetsa fruits and seeds from different topographical areas, throughout Thailand, were examined following WHO guideline for quality control of medicinal plant materials. The Z. rhetsa fruits and seeds were evaluated by microscopic and physicochemical studies. The GC-MS study showed the major phytoconstituents of Z. rhetsa are sabinene (56.62%), 4-terpineol (13.82%), germacrene (10.1%), gramma-terpinene (5.5%) and alpha-terpinene (3.5%). These pharmacognostic specifications with GC-MS can be used to develop some standard parameters for judge the quality, quantity and impurity of Z. rhetsa crude drug future.

花椒果实和种子的质量评估-泰国传统药物

Zanthoxylum rhetsa（Roxb。）DC或Ma-khwuang（芸香科）长期以来一直用于泰国的烹饪和传统医学中。它的果实和种子用于抗糖尿病，解痉，利尿和消炎。基于其药用价值，我们评估了红景天果实和种子的质量参数。按照世界卫生组织关于药用植物材料质量控制的指南，检查了整个泰国不同地形地区的十种红景天果实和种子样品。该Z. rhetsa果实和种子通过显微镜和物理化学研究评估。GC-MS研究显示了红景天的主要植物成分是sa烯（56.62％），4-萜品醇（13.82％），germ（10.1％），γ-萜品烯（5.5％）和α-萜品烯（3.5％）。这些带有GC-MS的药理学规范可用于开发一些标准参数，以判断红景天粗制药物未来的质量，数量和杂质。
