Each capsule contains 150 mg of Hawthorn Leaves & Flowers extract standardized to provide 2% Vitexin.

每粒胶囊含150毫克山楂叶（花）提取精华，含2%牧荆素。

Three compounds were isolated from the active part and identified as vitexin , vitexin glucoside, vitexin rhamnoside NMR data and physical and chemical character.

对有效部位进行了化学成分分离，得到了三个化合物，分别为牡荆素、牡荆素鼠李糖苷、牡荆素葡萄糖苷。

Using moderate resolution capabilities of a desk time-of-flight (TOF) instrument, the fragmentation regularity from electron impact mass spectra of vitexin was studied.

利用台式飞行时间质谱的中分辨本领，研究了牡荆素的电子轰击质谱的裂解规律，对裂解途径进行了完全的指认。
