摘要:研究了油橄榄叶中橄榄苦苷含量的变化规律,以及加工和提取条件对提取得率的影响;采用HPLC法测定橄榄苦苷的含量。对油橄榄叶中橄榄苦苷含量研究表明,一年生长期内有两个高峰期,分别是在2月份和5月份,其中2月份最高,两个低谷期则是在11月份和4月份;品种间差别很大,科拉地17.2%,最低的配多灵仅为1.65%;20年生较3年生的高。超声波辅助提取法较加热法提取得率高,自然阴干较烘干的提取得率高。
Seasonal variation of oleuropein content in olive leaves was investigated, and the influences of preparation and extraction factors to the yield were discussed. HPLC was used to determine the content of oleuropein. Results showed : content of oleuropein in a year has two peak periods,namely Feb. and May (among them: Feb. 〉 May), and two trough periods,namely Nov. and April. Huge differences existed among different breads. Keladi olive leaves have the highest oleuropein content of 17.2 % , in contrary, Peidaling olive leaves have the lowest oleuropein content of 1.65 %. The content of oleuropein of 20 years-old trees is much higher than that of 3 years old. Ultrasonic extraction is better than heat extraction. Natural drying of leaves superior to heat drying to obtain higher yield of oleuropein.
