摘要:
家蚕体内和丝中含有黄酮类物质,采用NaNO2-Al(NO3)3-NaOH比色法对其进行测定。结果表明,绿茧蚕品种茧层中黄酮类物质的含量是黄、紫荧光色茧蚕品种的5倍,后二者蚕品种茧层中黄酮类物质的含量相当;绿茧蚕品种蚕蛹中黄酮类物质的含量与紫荧光色茧蚕品种的相当,比黄荧光色茧蚕品种高出1.3倍,3类蚕品种蚕蛹中该物质的含量都明显高于茧层中的含量。

Abstract:
The content of flavonoids in silkworm and its silk was determined using NaNO2-Al(NO3)3- NaOH colorimetry. The results showed that?the flavonoid content in cocoon layers?of green silkworm?variety was five times higher than that in yellow and purple?fluorescent?color?silkworms?and no difference in flavonoid?content was observed in ?cocoon layers? of yellow and purple silkworm varieties. The content of flavonoids in cocoon pupas of green cocoon variety was equivalent to that of purple?fluorescent?color silkworm, but was 1.3 times higher than that in cocoon pupas of the yellow fluorescent?color?silkworm. The content of flavonoids in three varieties of silkworm pupasare was significantly higher than that in cocoon layers.
Key words:  silkworm race  cocoon layer  silkworm pupa  flavonoids
