摘要
Mature dry seeds of 13 American cowpea (Vigna sineilsis) cultivars were subjected to proximate analysis with the following results: moisture 9.6%; crude protein 23.9%; crude fat 1.6%; crude fiber 4.1%; ash 3.3%; and nonfiber carbohydrates by difference 57.7%. The sugars of these cultivars were extracted with 70% ethanol and separated by paper chromatography. On the basis of RG and Rf values, and several confirming tests, sucrose, raffinose, stachyose and verbascose were identified in these extracts. On a dry basis the average content of the cowpeas in these sugars was: sucrose 2.2%; raffinose 1.2%; stachyose 3.4%; and verbascose 0.9%. Copyright © 1979, Wiley Blackwell. All rights reserved
