简介

白藜芦醇和大黄素是虎杖中的主要功能成分。研究显示白藜芦醇和大黄素表现出广泛的抗氧化特性，如LDL胆固醇氧化和脂质过氧化反应。白藜芦醇同时显示出有助于心血管健康和活血，减轻疼痛，清热去湿，去毒去痰。其它成分包括丹蒽酮，大黄素甲醚和大黄酸都具有抗炎症，祛关节炎和抗微生物活性。

 

虎杖提取物功效

1. 退热和止痛作用

白藜芦醇通过多种不同的途径发挥治疗功效，其显示有一定的解热和止痛活性，正如在完整小鼠和大鼠身上研究所示（林和胡，1987）。其提取物显示可在不影响血压情况下赋予胃粘膜抵抗因胃分泌受压制而导致的应激性溃疡能力。

2. 抗癌，抗突变能力

作为抗氧化剂，抗突变剂和抗炎剂，白藜芦醇显示出对癌症的化学预防能力。其同样可诱导人体早幼粒细胞白血病细胞分化（抗增值作用）和抑制小鼠乳腺癌前组织病变发展。白藜芦醇同时还能抑制蛋白酪氨酸激酶这一催化酪氨酸磷酸化的物质。该激酶包含于有丝分裂调节的细胞之细胞质信息传导中。利用白藜芦醇抑制蛋白酪氨酸激酶可能通过阻止激酶功能而起抗突变作用。

3. 预防心脏和肝脏损伤

白藜芦醇可抑制小鼠肝部甘油三酸酯和胆固醇的沉积。其同样可通过抑制小鼠肝部脂肪过氧化反应而促使天冬氨酸转氨酶和丙胺酸转氨酶水平上升。对血清中这两种酶的分析给予了心脏和肝脏损伤良好的诊断信息。

4. 抗血栓功能

白藜芦醇可抑制脂氧合酶合成，该酶存在于白细胞，心脏，大脑，肺和脾中。因此白藜芦醇可防止血管中血液凝块的形成。且同样可抑制血小板在可乐宁这种抗高血压药物治疗后的集结。

5. 提升伤口治疗中的免疫系统活性

白藜芦醇还可通过增强免疫系统而促进烫伤愈合。罗（1993）研究了白藜芦醇在恢复烫伤小鼠的受抑制细胞性，体液性和非特异性免疫功能方面的功效。对白藜芦醇的受控使用提供了一种药物依赖式的免疫调节作用。罗等（1995）对不同程度严重烫伤小鼠研究显示白藜芦醇可恢复其受损功能如对抗原信号的回应能力，增生能力，白细胞介素Ⅱ合成能力和通过淋巴细胞的抗体合成能力。严重烧伤的动物在利用受控白藜芦醇治疗后其嗜中性粒细胞水平和嗜中性粒细胞黏附率恢复到接近普通水平，而且存活时间延长。
