摘要
通过不同取材,研究了红色、金黄色、白色和粉红色玫瑰花花瓣、花蕊、花萼和叶片清除DPPH·能力,结果表明,红色和金黄色玫瑰花瓣对DPPH·清除能力比白色和粉红色强;四种玫瑰花花蕊都有较强的DPPH·清除能力,且无显著差异;粉红色和金黄色玫瑰花花萼具有较强的DPPH·清除能力;在较高的浓度下四种玫瑰花的叶片同样有较强的DPPH·清除能力。在实验条件下,红色、金黄色花瓣以及不同花蕊50%DPPH·清除率(rs50)都小于芦丁的rs50。
The scavenging actitities of the crude aqueous extracts from petals,pistils,sepals and leaves of Rosa hybrida cv. Cardinal (red),Rosa hybrida cv. Tinke (white),Rosa hybrida cv. Golden (golden),and Rosa hybrida cv. Sunlight (pink) on DPPH^·were investigated in the paper. The results showed that the red and golden rose petals and pink and golden sepals had obviously stronger DPPH^·scavenging activities when compared to the same parts of four flowers. Pistils were found strong DPPH^·scavenging activities,as well as leaves in high dose. Additionally,in tested condition,50 percent DPPH^·scavenging activities (rs50) of four kinds of pistils and red and golden petals were weaker than that of rutin.
