生物活性

Ligustrazine (Chuanxiongzine), an alkylpyrazine isolated from Ligusticum wallichii (Chuan Xiong)[1], is present in french fries, bread, cooked meats, tea, cocoa, coffee, beer, spirits, peanuts, filberts, dairy products and soy products as fragrance and flavouring ingredienexhibits. Ligustrazine also has potential nootropic and anti-inflammatory activities in rats[2][3].

体外研究
(In Vitro)

Ligustrazine has been extensively used in China for cardiovascular and cerebrovascular diseases for about 40 years. Because of its effectiveness in multisystem, especially in cardiovascular. Ligustrazine also has been used in various diseases, such as coronary heart disease, diabetes, cancers, and liver injury[1].
