仿野生種植三葉青不同部位總黃酮分析及其抗炎、抗氧化能力比較

Analysis of Total Flavonoids in Different Parts of Wild Planting Tetrastigma hemsleyanum Diels et Gilg and Comparison of Their Anti-inflammatory and Antioxidant Capacity

  • 摘要: 目的:比較仿野生種植三葉青不同部位中總黃酮含量、抗氧化活性以及抗炎能力差異。方法:采用醇提工藝對仿野生種植三葉青莖葉、塊根、根須進行提取,比較不同部位間總黃酮含量差異;通過DPPH自由基、ABTS+自由基、羥自由基清除實驗以及鐵離子還原力測定,比較仿野生種植三葉青不同部位間抗氧化能力的強弱;采用脂多糖(LPS)誘導RAW264.7細胞作為炎癥模型,通過細胞NO的釋放量比較仿野生種植三葉青不同部位間的抗炎能力差異。結果:在最佳提取工藝條件下,測得仿野生種植三葉青莖葉、塊根、根須總黃酮含量分別為11.86±0.23、8.48±0.10、7.52±0.02 mg·g?1;建立三葉青HPLC指紋圖譜,共標定了10個共有峰,通過對照品指認出6號峰為蘆丁、8號峰為槲皮素、9號峰為山奈酚,并對其含量進行檢測,結果顯示塊根中三種指標成分含量均最高,其次根須,莖葉最低。檢測仿野生種植三葉青不同部位對DPPH自由基、ABTS+自由基以及羥自由基的IC50值,莖葉分別為0.2107、0.2315、0.7625 mg/mL;塊根分別為0.3134、0.3758、0.8967 mg/mL;根須分別為0.2058、0.2587、0.7856 mg/mL。三葉青莖葉、塊根、根須對鐵離子還原能力的吸光度值分別為0.172、0.153、0.184。當仿野生種植三葉青三部位的質量濃度在25~200 μg/mL之間時,它們不會對RAW264.7細胞造成毒性,能夠有效地抑制LPS誘導的NO釋放,從而達到良好的抗炎效果。結論:本研究結果為仿野生種植三葉青不同部位的質量評價提供參考,并對仿野生種植三葉青非藥用部位廢物再利用及后續全資源開發提供理論依據。

     

    Abstract: Objective: The content of total flavonoids, antioxidant activity and anti-inflammatory capacity in different parts of Tetrastigma hemsleyanum Diels et Gilg which imitated wild planting were compared. Methods: Stems, leaves, root tubers and root whiskers of wild imitating-planted Tetrastigma hemsleyanum Diels et Gilg were first extracted by alcohol extraction technology, and the content of total flavonoids was compared among different parts. Then DPPH free radical scavenging rate, ABTS+ free radical scavenging rate, hydroxyl free radical scavenging rate and ferric ion reducing power were used to evaluate the antioxidant capacity of different parts of plants. Meanwhile, lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation model was established to compare anti-inflammatory ability of different parts of wild planting Tetrastigma hemsleyanum Diels et Gilg by measuring the release of NO. Results: Under the optimal extraction conditions, the contents of total flavonoids in stem leaves, root tubers and root whiskers were 11.86±0.23, 8.48±0.10 and 7.52±0.02 mg·g?1, respectively. A total of 10 common peaks of Tetrastigma hemsleyanum Diels et Gilg were identified by HPLC fingerprint. Rutin (peak 6), quercetin (peak 8) and kaempferol (peak 9) were identified via comparisons with reference standards. The content of the three indexes was the highest in roots, followed by stems and leaves. The IC50 values of DPPH free radicals, ABTS+ free radicals and hydroxyl free radicals in different parts of the plant were detected, and the values of stem leaves were 0.2107, 0.2315 and 0.7625 mg/mL. Root tubers were 0.3134, 0.3758 and 0.8967 mg/mL. The roots were 0.2058, 0.2587 and 0.7856 mg/mL, respectively. The absorbance values of the reducing capacity of ferric ions in stem, tuber and root were 0.172, 0.153 and 0.184. Three parts of the wild imitating-wild plant were not toxic to RAW264.7 cells at the concentrations between 25~200 μg/mL and could effectively inhibit the release of NO induced by LPS that achieving a good anti-inflammatory effect. Conclusion: The results of this study provided a reference for the quality evaluation and a theoretical basis for waste recycling as well as subsequent whole resource development to the non-medicinal parts of Tetrastigma hemsleyanum Diels et Gilg from the wild.
