摘要:目的 考察蜜制和麸制对金樱子化学成分的影响。方法 以总多酚、总皂苷、总多糖、总氨基酸为评价指标,考察金樱子生品、蜜制品、麸制品中4类化学成分的变化情况;以体外对1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除率为评价指标,比较金樱子生品、蜜制品、麸制品的抗氧化活性。结果 金樱子生品、蜜制品、麸制品总皂苷含量分别为3.332%、4.880%、4.572%,总酚酸含量分别为1.92%、6.38%、7.30%,总多糖含量分别为35.99%、40.38%、36.86%,总氨基酸含量分别0.67%、0.76%、0.96%。经炮制后金樱子总多酚、总皂苷、总多糖、总氨基酸含量均升高,其中总多酚含量升高最为明显;金樱子生品、蜜制品、麸制品体外清除DPPH自由基的IC50分别为0.47、0.51、0.22 mg。结论 与生品比较,金樱子蜜制品和麸制品化学部位含量增高,抗氧化性增强。

Abstract: Objective To investigate the honey and bran of processing for chemical compositions of Rosae Laevigatae Fructus. Methods With total polyphenols, total saponins, total polysaccharides and amino acids as the evaluation indexes, changes of the chemical compositions of these four chemical components in Raw product, honey products, bran products of Rosae Laevigatae Fructus were studied; in vitro activity of DPPH radical clearance for evaluation index, antioxidant activity of raw products, honey products, bran products of Rosae Laevigatae Fructus were compared. Results Raw products, honey products, and bran products of total saponin content were 3.332%, 4.880%, and 4.572%; total phenolic contents were 1.92%, 6.38%, and 7.30%; total polysaccharide contents were 35.99%, 40.38%, and 36.86%; the total amino acid contents were 0.67%, 0.76%, and 0.96%. Total polyphenol, total saponins, total polysaccharides, and total amino acids of Rosae Laevigatae Fructus after processing increased, in which the total polyphenol was most obvious; DPPH radical scavenging IC50 of raw products, honey products, and bran products were 0.47, 0.51, and 0.22 mg, respectively. Conclusion Compared with raw product, the content of chemical fractions in honey products and bran products of Rosae Laevigatae Fructus increase, and oxidation resistance is enhanced.

金櫻子为蔷薇科蔷薇属植物金樱子Rosa laevigata Michx.的成熟果实,具有固精缩尿、涩肠止泻功效,用于治疗遗精滑精、遗尿尿频、崩漏带下、久泻久痢。金樱子的化学成分主要为三萜、有机酸、黄酮、鞣质、多糖等,具有提高机体免疫力、抗氧化、抗肿瘤、抑菌、抗病毒等药理活性[1]。炮制引起中药饮片变化主要包括两方面:一是整体化学成分变化,二是化学成分变化导致生物活性的改变。目前主要以几个单体化学成分含量变化或某一两个化学部位含量为标准评价炮制品质量,无法合理阐释中药炮制变化的内涵。本研究从整体化学成分角度出发,在前期研究[2]基础上,以总多酚、总皂苷、总多糖、总氨基酸为化学评价指标,以抗氧化为生物活性评价指标,研究金樱子不同炮制品的变化,为探讨其炮制原理提供参考。……
