L. is a traditionally important medicinal herb that has a rich source of bioactive phytoconstituents with biological benefits. The objective of this study was to assess the metabolic profile and in vitro biological potential of . The bioactive phytoconstituents were evaluated by preliminary phytochemical studies, estimation of polyphenolic contents, and gas chromatography-mass spectrometry (GC-MS) analysis of all fractions (crude methanolic, -hexane, ethyl acetate, and -butanol) of . The biological investigation was performed by different assays including antioxidant assays (DPPH, ABTS, CUPRAC, and FRAP), enzyme inhibition assays (urease and α-glucosidase), and hemolytic activity. The ethyl acetate extract had the maximum concentration of total phenolic and total flavonoid contents (394.30 ± 1.09 mg GAE·g DE and 137.35 ± 0.94 mg QE·g DE, respectively). Significant antioxidant potential was observed in all fractions by all four antioxidant methods. Maximum urease inhibitory activity in terms of IC value was shown by ethyl acetate fraction (10 ± 1.60 µg mL) in comparison to standard hydroxy urea (9.8 ± 1.20 µg·mL). The -hexane extract showed good α-glucosidase inhibitory efficacy (420 ± 20 µg·mL) as compared to other extract/fractions. Minimum hemolytic activity was found in crude methanolic fraction (6.5 ± 0.94%) in comparison to positive standard Triton X-100 (93.5 ± 0.48%). The GC-MS analysis of all extract/fractions of including crude methanolic, -hexane, ethyl acetate, and -butanol fractions, resulted in the identification of 24, 56, 25, and 9 bioactive compounds, respectively, with 80% quality index. Furthermore, the bioactive compounds identified by GC-MS were analyzed using in silico molecular docking studies to determine the binding affinity between ligands and enzymes (urease and α-glucosidase). In conclusion, possesses multiple therapeutical potentials, and further research is needed to explore its use in the treatment of chronic diseases.
L. 是一种传统的药用草本植物,具有丰富的生物活性植物化学成分,具有生物益处。本研究的目的是评估 的代谢谱和体外生物学潜力。通过初步的植物化学研究、多酚含量的估计以及所有馏分(粗甲醇、正己烷、乙酸乙酯和正丁醇)的气相色谱-质谱(GC-MS)分析来评估生物活性植物化学成分。通过不同的测定方法(DPPH、ABTS、CUPRAC 和 FRAP 抗氧化测定法、脲酶和 α-葡萄糖苷酶抑制测定法、溶血活性测定法)进行了生物学研究。乙酸乙酯提取物的总酚和总黄酮含量最高(分别为 394.30±1.09mgGAE·g DE 和 137.35±0.94mgQE·g DE)。所有四个抗氧化方法都表明所有馏分都具有显著的抗氧化潜力。以 IC 值表示,乙酸乙酯馏分的脲酶抑制活性最高(10±1.60μg·mL),与标准羟基脲(9.8±1.20μg·mL)相比。与其他提取物/馏分相比,正己烷提取物显示出良好的 α-葡萄糖苷酶抑制功效(420±20μg·mL)。与阳性标准曲拉通 X-100(93.5±0.48%)相比,粗甲醇馏分的溶血活性最低(6.5±0.94%)。对 的所有提取物/馏分(包括粗甲醇、正己烷、乙酸乙酯和正丁醇馏分)进行 GC-MS 分析,分别鉴定出 24、56、25 和 9 种生物活性化合物,质量指数均为 80%。此外,还通过 GC-MS 鉴定的生物活性化合物进行了计算机分子对接研究,以确定配体与酶(脲酶和 α-葡萄糖苷酶)之间的结合亲和力。总之, 具有多种治疗潜力,需要进一步研究以探索其在治疗慢性疾病中的应用。
