Roots of are a rich source of phytochemicals with high antioxidant potential and thus may possess health benefits. This study used the LC-MS technique to identify phytoconstituents in roots extract/fractions. Results revealed that -butanol fraction and ethanolic extract contained total phenolic and flavonoid contents with values of 155.64 ± 0.66 mgGAE/g DE and 194.94 ± 0.98 mgQE/g DE, respectively. Significant potential of antioxidants was observed by DPPH, CUPRAC and FRAP methods while the ABTS method showed moderate antioxidant potential. Maximum % inhibition for urease, tyrosinase and carbonic anhydrase was shown by ethanolic extract (73.39 ± 1.11%), -butanol soluble fraction (80.26 ± 1.59%) and ethyl acetate soluble fraction (76.50 ± 0.67%) which were comparable with thiourea (standard) (98.07 ± 0.74%), kojic acid (standard) (98.59 ± 0.92%) and acetazolamide (standard) (95.51 ± 1.29%), respectively, while all other extract/fractions showed moderate inhibition activity against these three enzymes. Hemolytic activity was also observed to range from 18.80 ± 0.42 to 3.48 ± 0.69% using the standard (triton X-100) method. In total, 28 and 20 compounds were identified tentatively by LC-MS analysis of ethanolic extract and -butanol soluble fraction, respectively. Furthermore, molecular docking was undertaken for major compounds identified by LC-MS for determining binding affinity between enzymes (urease, tyrosinase and carbonic anhydrase) and ligands. It was concluded that active phytochemicals were present in roots of with potential for multiple pharmacological applications and as a latent source of pharmaceutically important compounds. This should be further explored to isolate important constituents that could be used in treating different diseases.
根是植物化学成分的丰富来源,具有很高的抗氧化潜力,因此可能对健康有益。本研究使用 LC-MS 技术鉴定根提取物/馏分中的植物成分。结果表明,正丁醇馏分和乙醇提取物分别含有总酚和总黄酮含量,值为 155.64±0.66mgGAE/g DE 和 194.94±0.98mgQE/g DE。DPPH、CUPRAC 和 FRAP 方法显示出显著的抗氧化潜力,而 ABTS 方法显示出中等的抗氧化潜力。乙醇提取物(73.39±1.11%)、正丁醇可溶部分(80.26±1.59%)和乙酸乙酯可溶部分(76.50±0.67%)对脲酶、酪氨酸酶和碳酸酐酶的最大抑制率与硫脲(标准)(98.07±0.74%)、曲酸(标准)(98.59±0.92%)和乙酰唑胺(标准)(95.51±1.29%)相当,而其他所有提取物/馏分对这三种酶均显示出中等抑制活性。用标准(曲通 X-100)法测定溶血活性范围为 18.80±0.42%至 3.48±0.69%。通过 LC-MS 分析乙醇提取物和正丁醇可溶部分,分别暂定鉴定出 28 种和 20 种化合物。此外,还进行了 LC-MS 鉴定的主要化合物的分子对接,以确定酶(脲酶、酪氨酸酶和碳酸酐酶)与配体之间的结合亲和力。结论是, 根中含有潜在的多药效学应用和作为有前途的药物重要化合物来源的活性植物化学成分。这应该进一步探索,以分离可用于治疗不同疾病的重要成分。
