In vitro S. glabra中的酚类富集提取物(PEESG)通过70%乙醇提取且经HP-20柱色谱纯化。其抗氧化和抗炎活性分别通过自由基清除实验、还原力测定和脂多糖(LPS)诱导的RAW264.7细胞实验评估。PEESG显著清除DPPH和ABTS自由基,并对铁离子表现出显著的还原能力。特别是,在12.5-50 μg/mL浓度范围内,PEESG清除ABTS的效率显著高于抗坏血酸,与其清除DPPH的效率无显著差异。另外,PEESG显著抑制LPS诱导的RAW264.7细胞中的促炎介质(如一氧化氮(NO)、肿瘤坏死因子-α±(TNF-α±)、和白细胞介素-6(IL-6))的产生。此外,通过超高压液相色谱-电喷雾质谱(U-HPLC-ESI-MS)鉴定PEESG的主要成分,共识别出十七种成分,包括5-O-咖啡酰基紫萁酸、新琥珀薯蓣苷、薯蓣苷、新异琥珀薯蓣苷、异琥珀薯蓣苷、榕脂素及异榕脂素等。
