For exploring if the Equisetum hiemale L. has antiangiogenic activity , here we have a test for ethyl acetate extracted from Equisetum hiemale L. on angiogenic activity using the method of chorio allantioc membrane.

• 为了探讨木贼（Equisetum hiemale L.；） 是否具有抗血管生成活性，采用鸡胚绒毛尿囊膜法（Chorio Allantioc Membrane CAM）对木贼乙酸乙酯萃取部分进行了抗血管生成活性实验。
