摘要:

目的:优化提取桑黄总黄酮的最佳工艺条件,测定其体外抗氧化活性和对癌细胞的生长抑制作用。方法:以样品中总黄酮的提取率为指标,采用L9(34)正交试验对桑黄的超声辅助提取工艺参数进行优化;通过测定桑黄黄酮对·OH、O2·的清除能力等指标,探讨其抗氧化活性;采用MTT 法测定桑黄黄酮对大肠癌细胞CX-1 增殖反应的影响,研究其体外抗肿瘤活性。结果:桑黄总黄酮的最佳提取工艺为乙醇体积分数55%、料液比1:20(g/mL)、提取温度70℃、超声提取时间1.5h。桑黄黄酮可以有效清除·OH、O2·,对Fe2+ 诱发卵黄低密度脂蛋白(LDL)多不饱和脂肪酸(PUFA)过氧化反应具有抑制作用。桑黄黄酮提取物能够有效地抑制大肠癌细胞CX-1 的生长。结论:该工艺提取桑黄总黄酮,方法简单、耗时短。桑黄黄酮抗氧化能力强,有抑制癌细胞的作用,是一种有效的天然抗氧化剂。

Abstract:

Objective: To optimize the extraction conditions of total flavonoids from Phellinus igniarius and determine its antioxidant activity and inhibition effect on the growth cancer cells. Methods: The ultrasound-assisted extraction processing parameters for total flavonoids from Phellinus igniarius were optimized by orthogonal experiments through evaluating the extraction rate of total flavonoids. The antioxidant activity of total flavonoids was explored by evaluating the scavenging capability on hydroxyl and superoxide anion free radicals. The anti-tumor activity of total flavonoids was evaluated by MTT assays through determining the inhibition effect on the proliferation of human colorectal cancer CX-1 cells in vitro. Results: The optimal extraction processing parameters were ethanol concentration of 55%, extraction temperature of 70 ℃, material-liquid ratio of 1:20 (g/mL) and extraction time of 1.5 h. The total flavonoids from Phellinus igniarius exhibited strong scavenging capability on hydroxyl and superoxide anion free radicals. Meanwhile, the total flavonoids could effectively inhibit the peroxidation of polyunsaturated fatty acids. Moreover, the total flavonoids had strong inhibitory effect on the growth of human colorectal cancer CX-1 cells. Conclusion: This extraction processing for total flavonoids is sample and convenient. The total flavonoids from Phellinus igniarius have strong antioxidant activity and strong inhibitory effect on the growth of cancer cells. Therefore, The total flavonoids from Phellinus igniarius have a promising potential as the effective natural antioxidant and anticancer components.
