    • An extract of Chinese blackberry (Rubus suavissimus) has been found to inhibit angiogenesis, and two active fractions isolated. Gallic acid was shown to be one of the active anti-angiogenic compounds by an in vitro human angiogenesis model. Aqueous extracts from other plants either known or found to have gallic acid were also found to have anti-angiogenic activity. Various derivatives of gallic acid were found to inhibit angiogenesis. The extract from Chinese blackberry also slowed the growth of a pancreatic tumor and of corneal neovascularization in rats. Extracts from pomegranate were shown to inhibit angiogenesis in fat tissue. Extracts from Rubus spp, and other plants with gallic acid, and gallic acid and its derivatives will be useful for treating various diseases associated with neovascularization, including diabetic retinopathy, psoriasis, tumors, obesity, cancer, rheumatoid arthritis, etc.
    • 已经发现中国黑莓(Rubus suavissimus)的提取物抑制血管生成,并分离出两种活性级分。 没食子酸通过体外人血管生成模型显示为活性抗血管生成化合物之一。 已知或发现有没食子酸的其他植物的水提取物也被发现具有抗血管生成活性。 发现没食子酸的各种衍生物抑制血管生成。 中国黑莓的提取物也减缓了大鼠胰腺肿瘤和角膜新血管形成的发生。 石榴提取物显示抑制脂肪组织中的血管发生。 来自红豆杉和其他具有没食子酸的植物和没食子酸及其衍生物的提取物可用于治疗与新生血管形成相关的各种疾病,包括糖尿病性视网膜病变,牛皮癣,肿瘤,肥胖症,癌症,类风湿性关节炎等。
