摘要

The profiles and bioactivities of flavonoids extracted from Dryopteris erythrosora were investigated. The total flavonoid content in full plant of D. Erythrosora is about 14.33%. The main flavonoids in D. Erythrosora were identified as gliricidin 7-O-hexoside, apigenin7-O-glucoside, quercetin 7-O-rutinoside, quercetin 7-O-galactoside, keampferol 7-O-gentiobioside, keampferol-3-O-rutinoside, myricetin 3-O-rhamnoside and quercitrin by means of HPLC-DAD-ESI-MS. Flavonoids (0.36mg/ml) extract from D. erythrosora showed similar 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH), 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS), superoxide anion scavenging potential and ferric reducing antioxidant potential (FRAP) with that of rutin (0.80mg/ml). However, the antioxidant power by FRAP assay of 0.36mg/ml flavonoids extract from D. erythrosora was much weaker than that of 0.80mg/ml rutin. Moreover, the flavonoids extract from D. erythrosora showed obvious cytotoxic effects on A549 cells. The antioxidant activities of flavonoids extracts from 69 ferns showed a significant reciprocal proportion to the total flavonoids contents. The flavonoids extract from D. erythrosora exhibited a dose-dependent inhibition against acetylcholinesterase. Moreover, the anticancer activity slightly increased with improving antioxidant potential of fern flavonoids. Fern flavonoids are excellent function foods.

Erythrosora中的主要类黄酮被鉴定为神经节苷脂7-O-己糖苷,芹菜素7-O-葡萄糖苷,槲皮素7-O-芸香糖苷,槲皮素7-O-半乳糖苷,keampferol 7-O-gentiobioside,keampferol-3-O-通过HPLC-DAD-ESI-MS测定芸香苷,杨梅素3-O-鼠李糖苷和槲皮苷。从红衣藻中提取的类黄酮(0.36mg / ml)显示相似的2,2-二苯基-1-吡啶并肼基自由基(DPPH ),2,2'-叠氮基双-(3-乙基苯并噻唑啉-6-磺酸)自由基(ABTS ),超氧阴离子清除电位和还原铁三价抗氧化电位(FRAP)与芦丁(0.80mg / ml)。然而,通过FRAP分析,从红毛杜鹃中提取0.36mg / ml类黄酮的抗氧化能力比0.80mg / ml芦丁要弱得多。此外,从D. erythrosora中提取的黄酮类化合物对A549细胞具有明显的细胞毒性作用。 69种蕨类植物黄酮提取物的抗氧化活性与总黄酮含量呈显着倒数比例。红叶杜鹃的类黄酮提取物表现出对乙酰胆碱酯酶的剂量依赖性抑制作用。此外,随着蕨类黄酮抗氧化能力的提高,抗癌活性略有提高。蕨类黄酮是极好的功能食品。
