Vallesia glabra

Floriani has recently examined bark from Aspidosperma quebracho bianco Schlecht f. pendulas Speg, in which he found the known alkaloids, quebrachine (yohimbine) and aspidospermine, as well as Hesse s aspidosamine, C2gH2g02N2, and a new base, aspidospermicine, Ci Hj ON, l-SHjO (1938). Hartmann and Schlittler have shown that the alkaloid vallesine from Vallesia glabra (Apocynaceae) is aspidospermine, and this has been confirmed by Deulofeu et aJ. who have also found it in V. dichotoma. Later Schlittler and Rottenberg by chromatographic analysis of the mother liquors of aspidospermine isolated a second alkaloid for which they used the old name Vallesine (1948). ... [Pg.511]

Vallesine (XXXVIII) and palosine (XXXIX) are respectively the A,-formyl and Aa-propionyl analogs of aspidospermine (II). Vallesine which occurs in Vallesia glabra and V. dichotoma (Volume II and Ref. 41) has been related to aspidospermine (39, 25) and has therefore structure XXXVIII. [Pg.400]
