摘要
以垂序商陆（ＰｈｙｔｏｌａｃａａｍｅｒｉｃａｎａＬ．）浆果为原料，采用水提取醇沉杂质甲乙混合液清除皂甙类物质的方法进行红色素的提取，色素粗品得率为４８５％，其中甜菜苷含量为３６９％；色素粗品质量初步检验结果为，总糖含量１１２％，还原糖７５％，铅浓度４１．３μｇ／ｇ，溶解性４２ｓ，分散性（Ａλ５２０）０３２３，吸湿性较强；经氯仿硫酸显色法和紫外扫描法检测，表明色素中皂甙类物质（即所谓“商陆毒素”）已基本清除。
The extraction technology of red pigment from Phytolacca americana L. berry and the methods of detoxin from the pigment were studied. The results showed that the procedure of water extraction alcohol precipitation for deimpurity detoxin by A B mixed solvent gave rather satisfied results, the productivity of crude pigment was 4.85%, and with 3.69% betanin in it. The determined quality criteria of crude pigment were as follows: total carbohydrates 11.2%, reductive sugars 7.5%, lead 41.3 μg/g, solubility 42 seconds, despersibility (A λ520 ) 0.323, with stronger moisture absorptivity. Saponin was undetectable in crude pigment product by chloroform sulphuric acid assay and UV scanning, accordingly it indicated the toxin was removed.
