摘要
滇牡丹是我国西南特有的野生牡丹,属于濒危物种,在观赏、新品种培育及药用等方面均具有重要的开发前景和利用价值。为研究滇牡丹果荚中的抗氧化活性物质,用其乙酸乙酯萃取物中化合物清除DPPH能力研究了其抗氧化能力,并通过TLC、1H-NMR和13C-NMR对具有抗氧化活性物质进行分析。结果表明,滇牡丹果荚乙酸乙酯萃取物中有多种单体化合物,其中有8种含量较多,用于测定其抗氧化能力,并且仅有2种化合物具较强的抗氧化活性,其余6种化合物不具抗氧化活性。具有抗氧化活性的化合物分别是2,6-二羟基-4-甲基苯甲酸乙酯和邻羟基苯甲酸丙酯。
Paeonia delavayi Franch was endangered species which only distributed in southwest of China, and it is a very important part for ornamental, medicinal and new breeds. In order to explore antioxidative compounds from siliques of P. delavayi, the capacity of scavenging free radical （as DPPH） of monomer compounds from ethyl acetate extracts were tested, and then its structures were identified by TLC, 1 H - NMR and 13C -NMR. The results showed that variety monomer compounds were included in ethyl ace- tate extracts, but majority monomer compounds with low content were not tested antioxidant activity, ex-cept eight monomer compounds, six monomer compounds have not antioxidant activity, but other tow have high antioxidant activity, and they were 2, 6 - dihydroxy - 4 - methyl benzoic acid ethyl ester and adjacent hydroxyl benzoic acid propyl ester, respectively.
