我国很早就有利用猕猴桃根茎叶的提取物作颜料和墨水的记载。在民间,人们利用其根治疗肿瘤、肝炎,用其叶治疗烫伤等,这些都或多或少地利用了鞣质的性质。本文对中华猕猴桃根茎叶中鞣质含量做了初步研究。1.材料与试剂猕猴桃植株于1992年4月底采自吉首市郊,经我校生物系石泽亮副教授鉴定为3～4年生中华猕猴桃。2.鞣质的提取及定性检验分别取根、茎、叶约200g,用60%的丙酮浸泡3d,各2次。合并浸液,回收丙酮,过滤,浓缩滤液,干燥,得 In China, the use of extracts of kiwifruit roots, stems and leaves as pigments and inks was recorded very early. In folk, people use their roots to treat tumors, hepatitis, and their leaves to treat burns, which all use the nature of tannins more or less. A preliminary study on the content of tannin in rhizomes of Chinese kiwifruit was made in this paper. 1. Materials and reagents Kiwifruit plants were collected from the outskirts of Jishou City at the end of April 1992. They were identified as 3-4 years old Chinese kiwifruit by Associate Professor Shi Zeliang of the Department of Biology of our school. 2. Extraction and Qualitative Test of Tannins About 200 g of roots, stems and leaves were respectively taken and soaked in 60% acetone for 2 days. Combine the leaching solution, recover the acetone, filter, concentrate the filtrate, and dry it.
