叶绿素**分子式：C35H28MgN4O5分子量：608.91CAS号：519-62-0性质：叶绿素c：稍红色六角形或四边形板状结晶。溶于甲醇、乙醇和乙酸乙酯，几乎不溶于醚和丙酮。最大吸收值（丙酮）628，580，442nm。制备方法：大多以植物（如菠菜等）或干燥的蚕砂为原料提取叶绿素。例如从蚕砂提取叶绿素可采用下述方法。有机溶剂提取：取洁净的蚕砂，用70%以上工业乙醇调成浆状，过滤出暗绿色溶液，再晾干而得。另一种操作是将45份石油醚、15份甲醇、4份苯混合，与洁净的蚕砂混合调浆，过滤，滤液用水洗4次。在有机提取液中加少量硫酸钠除去残留水分，过滤，滤液回收溶剂后即得叶绿素。物理法分离：将0.4mol/L稀蔗糖液和0.06mol/L磷酸钾稀溶液（pH为6-7）按1：1混合成缓冲介质。每2kg蚕砂加1L左右缓冲介质，混合均匀，用多层砂布滤出绿色的悬液，放入低温离心机离心5-10min，以水洗涤沉淀，再离心一次得叶绿素沉淀物。叶绿素用草酸处理，可得无镁的脱镁叶绿素，再引入镁转回成叶绿素。用强酸除去植醇和镁则得脱镁叶绿酸，植醇也可重新引入。水解则除去植醇和甲醇，得叶绿酸。大多以植物（如菠菜等）或干燥的蚕砂为原料提取叶绿素。例如从蚕砂提取叶绿素可采用下述方法。有机溶剂提取：取洁净的蚕砂，用70%以上工业乙醇调成浆状，过滤出暗绿色溶液，再晾干而得。另一种操作是将45份石油醚、15份甲醇、4份苯混合，与洁净的蚕砂混合调浆，过滤，滤液用水洗4次。在有机提取液中加少量硫酸钠除去残留水分，过滤，滤液回收溶剂后即得叶绿素。物理法分离：将0.4mol/L稀蔗糖液和0.06mol/L磷酸钾稀溶液（pH为6-7）按1：1混合成缓冲介质。每2kg蚕砂加1L左右缓冲介质，混合均匀，用多层砂布滤出绿色的悬液，放入低温离心机离心5-10min，以水洗涤沉淀，再离心一次得叶绿素沉淀物。叶绿素用草酸处理，可得无镁的脱镁叶绿素，再引入镁转回成叶绿素。用强酸除去植醇和镁则得脱镁叶绿酸，植醇也可重新引入。水解则除去植醇和甲醇，得叶绿酸。用途：叶绿素用于肥皂、矿油、蜡和精油的着色。叶绿素或叶绿酸的衍生物，例如叶绿素铜[11006-34-1]、叶绿酸铁钠、叶绿酸铜钠，用于食品、糖果、饮料、牙膏等作着色剂和脱臭剂。叶绿酸衍生物可与杀菌剂洁尔灭、卤卡班等并用作为臭化妆品的配方。
