我国不同产地荒漠肉苁蓉品质分析及其综合评价

Quality Analysis and Comprehensive Evaluation of Cistanche deserticola from Different Origins in China

  • 摘要: 为了明确我国不同产地荒漠肉苁蓉的品质差异,以我国不同沙漠地区的荒漠肉苁蓉为原料,对其不同部位(根部、中部、顶部)生物活性物质含量及其抗氧化活性进行测定,并进行多元统计分析。结果表明:产地和部位对荒漠肉苁蓉生物活性物质含量和抗氧化活性具有明显影响。腾格里沙漠南部(D)样品中总多酚和毛蕊花糖苷平均含量较高,分别为17.66和6.98 mg/g DW,该样品对ABTS+和DPPH自由基清除能力较强,IC50平均值分别为1.48和0.38 mg/mL。古尔班通古特沙漠南部(E)样品中总黄酮平均含量最高,为16.58 mg RE/g DW。巴丹吉林沙漠(A)样品中总三萜平均含量最高,为18.63 mg OAE/g DW。古尔班通古特沙漠北部(F)样品中总多糖和总原花青素平均含量较高,分别为31.18 mg DE/g DW和4.71 PCE/g DW。腾格里沙漠北部(C)样品中松果菊苷平均含量最高,为17.75 mg/g DW,该样品对羟基自由基清除能力最强,平均IC50值为3.05 mg/mL。主成分分析(Prin-cipal component analysis,PCA)共提取3个主成分,累计方差贡献率为85.43%;通过系统聚类分析(Hierarchical cluster analysis,HCA)将样品分为三个类群,其中第一、二类群的四个产地(A、B、C、D)分布在内蒙古和甘肃地区,综合评分为前四名。本研究结果将为我国荒漠肉苁蓉品质评价、产品开发及其标准化提供理论依据。

     

    Abstract: The present study aims at clarifying the quality differences of Cistanche deserticola (CD) from different areas. The contents of bioactive compounds extracted from different parts (root, middle and top stems) and their antioxidant activities were comparatively analyzed. The results showed that the contents and antioxidant activities of bioactive components were significantly affected by origins and parts. The samples from the southern Tengger desert (D) showed high concentrations of total polyphenols (17.66 mg GAE/g DW) and verbascoside (6.98 mg/g DW). These compounds showed high scavenging abilities against ABTS+ (IC50=1.48 mg/mL) and DPPH (IC50=0.38 mg/mL) free radical. Samples from the southern Gurbantunggut desert (E) showed the highest content of total flavonoids (16.58 mg RE/g DW). The highest content of total triterpenoid appeared in the sample from Badangirin desert (A) (18.63 mg OAE/g DW). Samples from the Gurbantunggut desert (F) had polysaccharides and procyanidins at levels of 31.18 and 4.71 mg PCE/g DW, respectively. The samples from the northern Tengger desert (C) had the highest echinoside content (17.75 mg/g DW) and hydroxyl radical scavenging ability (IC50=3.05 mg/mL). Three principal components were extracted by principal component analysis (PCA) with a cumulative variance contribution rate of 85.43%. Through hierarchical cluster analysis (HCA), the samples were divided into three groups. The four producing areas (A, B, C and D) of the first and second groups were distributed in Inner Mongolia and Gansu, and the comprehensive score was the top four. The results of this study would provide a theoretical basis for quality evaluation, product development and standardization of Cistanche deserticola in China.
