0
()
摘要:
采用改进的吸附层析法分离蚕沙申的脂溶性色素,层析结果出现八种物质的色谱带。用Beckman DU—7型自动扫描分光光度计对这八种物质分别进行了分析鉴定,结果表明:蚕沙中含有胡萝卜素、叶绿素a、叶绿素b、叶绿素衍生物和类胡萝卜素衍生物等色素。

ISOLATION AND IDENFIFICATION OF FAT-SOLUBLE PIGMENTS FROM FAECALA MATTER OF THE SILKWORM, BOMBYX MORI
()
Abstract:
The fat-soluble pigments from faecal matter of the silkworm were isolated by a modified method of the thin layer chromatograph. This process showed 8 chromatographic bands. These chromatogranhic components were scanned with Beckman DU-7 chromatograph. The result shows that the excrement of the silkworm larvae contains such pigments as carotene, chlorophyll a and b, chlorophyll derivatives and carotenoid derivatives.
Key words:  Faecal matter of silkworm,Fat-soluble pigment,Thin layer chromatograph
