Although there is evidence of the benefits of propolis on human health, the vast majority of studies have been conducted using animal models. The present study includes the chemical characterization and clinical evaluation of the effects of the oral administration of propolis solution on the oxidative status and modulation of lipids in a human population in Talca, Chile. Chemical characterization of propolis, total phenol, flavonoids, and total antioxidant capacity were determined by ORAC. Identification of phenols and flavonoids in propolis was assessed by HPLC-DAD. A double-blind, placebo-controlled clinical trial was conducted. Subjects provided informed consent form and the Bioethics Committee of the Universidad de Talca approved protocol. Eligible subjects ( = 67) were randomized in two groups: propolis ( = 35) and placebo ( = 32). All subjects were evaluated at 0 (baseline), 45, and 90 days. In the propolis group, we observed that increases in HDL-c went from 53.9 ± 11.9 to 65.8 ± 16.7 mg/dL ( < 0.001) from baseline to 90 days. Compared to placebo subjects, consumption of propolis induced a net increase in GSH levels ( < 0.0001) and a decrease ( < 0.001) in TBARS levels for the propolis group. Our findings indicate potential benefits of propolis use in human health. The use of propolis appears to have positive effects on oxidative status and improvement of HDL-c, both of which contribute to a reduced risk of cardiovascular disease.
尽管有证据表明蜂胶对人类健康有益,但绝大多数研究都是使用动物模型进行的。本研究包括对智利塔尔卡市人群口服蜂胶溶液对氧化状态和脂质调节作用的化学表征及临床评估。通过氧自由基吸收能力(ORAC)测定蜂胶的化学表征、总酚、黄酮类化合物和总抗氧化能力。通过高效液相色谱-二极管阵列检测法(HPLC-DAD)评估蜂胶中酚类和黄酮类化合物的鉴定。进行了一项双盲、安慰剂对照的临床试验。受试者提供了知情同意书,塔尔卡大学伦理委员会批准了该方案。符合条件的受试者(n = 67)被随机分为两组:蜂胶组(n = 35)和安慰剂组(n = 32)。所有受试者在第0天(基线)、45天和90天进行评估。在蜂胶组中,我们观察到从基线到90天,高密度脂蛋白胆固醇(HDL-c)水平从53.9±11.9毫克/分升增加到65.8±16.7毫克/分升(P < 0.001)。与安慰剂组受试者相比,蜂胶组食用蜂胶后谷胱甘肽(GSH)水平净增加(P < 0.0001),丙二醛(TBARS)水平降低(P < 0.001)。我们的研究结果表明蜂胶在人类健康方面具有潜在益处。使用蜂胶似乎对氧化状态和HDL-c的改善有积极作用,这两者都有助于降低心血管疾病风险。
