Abstract:
Phytochemical study on the plant Premna integrifolia L. led to the isolation of twelve compounds. In which, a new acylated iridoid glycoside, 6- O-(3″- O-acetyl-2″- O-trans-p-coumaroyl)-α-L-rhamnopyranosylcatalpol (premnacorymboside A) (1), was isolated from the flowers along with 10- O-trans-p-methoxycinnamoylcatalpol (3) and verbascoside. From the leaves, a new iridoid glycoside, 6- O-(3″- O-trans-p-coumaroyl)-α-L-rhamnopyranosylcatalpol (premnacorymboside B) (2), together with 10- O-trans-p-methoxycinnamoylcatalpol (3), scutellarioside II (4), premnaodoroside A (5), 1- O-trans-p-coumaroyl-α-L-rhamnopyranoside, hexyl glucoside, 4-hydroxy-2-methoxybenzaldehyde, and 4-hydroxybenzaldehyde were obtained. The new compound premnacorymboside A (1) and scutellarioside II (4), were also isolated from the stem bark along with quercetin 3-rutinoside and leonuriside A. The structure determinations were based on physical and spectroscopic evidence.
