Ayet, G. | Muzquiz, M. | Burbano, C. | Robredo, L. M. | Cuadrado Hoyos, María Carmen | Price, K. R.
The seeds of different legumes (Lupinus albus var. Multolupa, Lens culinaris var. Magda 20, Cicer arietinum type Kabuli, Phaseolus vulgaris var. Guerniquesa, Vicia faba var. Alameda) were analysed for soyasaponin content and soyasapogenol composition using different chromatographic techniques. The soyasapogenol was present in all species, except in L. albus; the content ranged from 0.02 mg/g in V. faba var. Alameda to 1.21 mg/g in P. vulgaris var. Guerniquesa. Two soyasaponins were detected by FAB-MS. Soyasaponin I was detected in the L. culinaris, C. arietinum, V. faba and P. vulgaris extracts and soyasaponin V in the P. vulgaris extracts. © 1996, Sage Publications. All rights reserved.
