摘要: 以恩施州海拔1 020 m(L-GC)与1 680 m(H-GC)采集的五倍子(Galla chinensis)为材料,采用HPLC法测定其没食子酸含量,并系统比较2种样品提取物的抑菌、抗癌及抗氧化活性。结果表明,H-GC的没食子酸含量(492.8 mg/g)显著高于L-GC(203.9 mg/g)。在抗氧化活性方面,H-GC提取物(H-MEGC)的DPPH清除IC50为5.64 μg/mL,显著优于L-GC提取物(L-MEGC,IC50为19.96 μg/mL)。2种提取物对A549肺癌细胞均具有显著抑制效果,IC50分别为25.72 μg/mL(L-MEGC)与27.43 μg/mL(H-MEGC),二者组间无显著差异。在抑菌试验中,100 mg/mL的H-MEGC对部分供试菌株(枯草芽孢杆菌、苏云金芽孢杆菌、鲍曼不动杆菌)的抑制效果优于L-MEGC。随着海拔升高,恩施州五倍子的没食子酸含量增加,其抗氧化能力增强,对部分测试菌株的抑菌活性有所提高,而对A549细胞抑制活性无显著影响。

Abstract: Galla chinensis samples collected from Enshi Prefecture at altitudes of 1 020 m (L-GC) and 1 680 m (H-GC) were utilized. The gallic acid content was determined by HPLC, and the antibacterial, anticancer, and antioxidant activities of the two extracts were systematically compared. The results showed that the gallic acid content of H-GC (492.8 mg/g) was significantly higher than that of L-GC (203.9 mg/g). In terms of antioxidant activity, the H-GC extract (H-MEGC) exhibited a DPPH scavenging IC50 value of 5.64 μg/mL, which was significantly better than that of the L-GC extract (L-MEGC, IC50=19.96 μg/mL). Both extracts significantly inhibited the proliferation of A549 lung cancer cells, with IC50 values of 25.72 μg/mL (L-MEGC) and 27.43 μg/mL (H-MEGC), and there was no significant difference between the two groups. In antibacterial assays, H-MEGC at 100 mg/mL showed stronger inhibition against some tested strains (Bacillus subtilis, Bacillus thuringiensis, and Acinetobacter baumannii) compared to L-MEGC. With increasing altitude, the gallic acid content, antioxidant capacity, and antibacterial activity of Enshi Prefecture Galla chinensis against certain strains were enhanced, while its inhibitory effect on A549 cells was not significantly affected.
