is a plant that has been used amongst others medicinally to treat wounds. The aim of this study was to assess the wound healing ability of Hot water, methanol, ethyl acetate, and hexane extracts were prepared. Thin layer chromatography (TLC) and ultra-performance liquid chromatography time of flight mass spectrometry (UPLC-TOF-MS) were used to determine the phytochemical classes and genus specific compounds present in the plant. Cytotoxicity was assessed in the SC-1 fibroblast and EA.hy926 endothelial hybrid cell lines using the sulforhodamine B assay. The effect of the extracts on cellular migration in both cell lines was assessed using the scratch assay. The major phytochemical classes detected in the extracts using TLC were alkaloids, coumarins, flavonoids, glycosides, phenolics, saponins, sterols, and terpenoids. The genus-specific compounds punicalagin, sericoside, anolignan B, and arjunic acid were identified in the extracts by means of UPLC-QTOF-MS. Cytotoxicity was not observed after 24 h of exposure and a generally low cytotoxic trend was noted after 72 h. A significant (p < 0.05) enhancement of cell migration in both cell lines was noted in the scratch assay. The wound healing ability of is mainly attributed to the migratory and proliferative activity of the extracts responsible for the acceleration of wound closure. Isolation and individualized testing of the active compounds is warranted.
是一种在医学上被用于治疗伤口的植物。本研究的目的是评估其伤口愈合能力。制备了热水、甲醇、乙酸乙酯和己烷提取物。采用薄层色谱(TLC)和超高效液相色谱飞行时间质谱(UPLC - TOF - MS)来确定该植物中存在的植物化学类别和属特异性化合物。使用磺基罗丹明B测定法在SC - 1成纤维细胞和EA.hy926内皮杂交细胞系中评估细胞毒性。使用划痕试验评估提取物对两种细胞系中细胞迁移的影响。通过TLC在提取物中检测到的主要植物化学类别为生物碱、香豆素、黄酮类、糖苷、酚类、皂苷、甾醇和萜类。通过UPLC - QTOF - MS在提取物中鉴定出属特异性化合物石榴皮素、丝胶苷、阿诺木脂素B和阿朱那酸。暴露24小时后未观察到细胞毒性,72小时后观察到总体较低的细胞毒性趋势。在划痕试验中,两种细胞系的细胞迁移均有显著(p < 0.05)增强。其伤口愈合能力主要归因于提取物的迁移和增殖活性,这些活性加速了伤口闭合。有必要对活性化合物进行分离和单独测试。
