以垂序商陆( Phytolacca americana L.) 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 4.85%, 其中甜菜苷含量为 3.69 %;色素粗品质量初步检验结果为, 总糖含量 11.2%, 还原糖 7.5%, 铅浓度 41.3 μg/g , 溶解性 42 s, 分散性( Aλ520) 0.323, 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-detox in 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 ( Aλ520 ) 0 .323, with stronger moisture absorptivity .Saponin was undetectable in crude pigment product by chloroformsulphuric acid assay and UV scanning, accordingly it indicated the toxin was removed .
