Triterpenoidic glycosides from Caryota urens

From the leaves of Caryota urens, two new triterpenoidic glycosides along with two known compounds have been isolated. Their structures were elucidated by chemical and physical data. [IR. [1]H-NMR, [13]CNMR and Mass Spectra]

Chemical constituents of cassia siamea [fabaceae]

Two coumarins named as bergapten and seselin along with three flavonoids named as 5-methoxy-4'- hydroxy-6,7-methylenedioxyisoflavone,5 ,4'-dihydroxy- 6,7-methylenedioxyisoflavone and 5.7.4'-trihydroxy-3'6 dimethoxyisoflavone have been isolated from leaves of Cassia siamea. Their structure have been elucidated on the basis of chemical and spectral evidences ['H-NMl7, IR, UV, and Mass]

Triterpenoids from acacia tortilis

From the leaves of Acacia tortilis, a new triterpene of lupane series along, with four known triterpenes have been isolated. Their structures were elucidated by chemical and physical data [IR. 1H-NMR, 13C-NMR and Mass spectra]
