叶绿素是良好的天然色素,在医药上具有广泛的用途。天然叶绿素多以蚕砂、雏菊、菠菜、绿藻为原料提取,以竹叶提取尚未规模开发。竹叶叶绿素含量高,每百克鲜竹叶含叶绿素达400～500毫克,而且富含维生素C、氨基酸、叶蛋白与矿物质。我国现有竹林总面积为5000余万亩,竹子约300亿株,以每株竹子再生竹叶2公斤计,每年在竹叶中损失掉的叶绿素就在20万吨以上。因此,从竹叶中提取叶绿素具有重大现实意义及广阔前景。以竹叶为原料提取叶绿素的工 Chlorophyll is a good natural pigment and has a wide range of uses in medicine. Natural chlorophyll is mostly extracted from silkworm sand, daisies, spinach, and green algae, and bamboo leaf extraction has not yet been developed. The content of chlorophyll in bamboo leaves is high. Each hundred grams of fresh bamboo contains 400-500 mg of chlorophyll, and is rich in vitamin C, amino acids, leaf protein and minerals. The total area of ​​existing bamboo forests in China is more than 50 million mu, and about 30 billion bamboos. The amount of chlorophyll lost in bamboo leaves is more than 200,000 tons per year based on 2 kilograms of renewable bamboo leaves per bamboo. Therefore, the extraction of chlorophyll from bamboo leaves has great practical significance and broad prospects. The extraction of chlorophyll from bamboo leaves
