| Abstract: | The seeds of 9 members of the subgenusCeratotropis (Piper) Verdc., namelyVigna aconitifolia (Jacq.) Maréchal,V. angularis (Willd.) Ohwi et Ohashi,V. minima (Roxb.) Ohwi et Ohashi,V. nakashimae (Ohwi) Ohwi et Ohashi,V. reflexo-pilosa Hayata,V. umbellata (Thumb.) Ohwi et Ohashi,V. mungo (L.) Hepper,V. radiata (L.) Wilczek andV. sp., have been examined. On their low molecular weight carbohydrate compositions, this subgenus has been divided into 2 subgroups,
mungo-radiata group and angularis group. Four other species referred to the subgeneraPlectotropis (Schumach.) Bak.,Lasiospron (Benth. emend Piper) Maréchal, Mascherpa et Stainier andVigna, V. vexillata (L.) A. Rich.,V. lasiocarpa (Benth.) Verdc.,V. marina (Burm.) Merr. andV. unguiculata (L.) Walp., were also analyzed and they had distinctive carbohydrate compositions. 1d-4-O-methyl-myo-inositol and 1d-5-O-(α-d-galactopyranosyl)-4-O-methyl-myo-inositol were detected in all species examined exceptV. vexillata, V. mungo andV. radiata. |
