Abstract

Eight compds. were isolated from the leaves of Jacaranda ovalifolia R. Br. and were identified as: 6'-​Ph acetic acid ester of glucose (1)​, Me p-​hydroxy Ph acetate (2)​, zizybeoside 1 (3)​, phenethyl alc. 8-​O-​β-​D-​glucopyranosyl-​(1→2)​-​β-​D-​glucopyranoside (4)​, acteoside (5)​, isoacteoside (6)​, apigenin 7-​O-​β-​D-​glucuronopyranoside (7)​, and jacaranone (8)​.  The structures of the compds. were detd. by phys., chem. and spectroscopic methods.  Compd. 1 is isolated here probably for the first time from a natural source, compds. 2, 3, 4, 6 and 7 have been isolated for the first time from the genus Jacaranda, compd. 8 was isolated for the first time from J. ovalifolia R. Br., and compd. 5 was previously isolated from J. ovalifolia.
