SPECTROSCOPIC ANALYSIS AND ANTI- INFLAMMATORY ACTIVITY OF PLUMERIA RUBRA L.

ABSTRACT

An investigation was designed for the phytochemical screening by spectroscopic techniques and to determine the anti-in?ammatory activity of Plumeria rubra L. leaves extract. The qualitative UV-VIS spectrum showed the peaks at 333.15 with absorption 0.0731 respectively. The FT-IR spectrum of the Plumeria rubra L. showed the -1 -1 -1 -1 -1 -1 absorption at 1019.79 /cm-1, 1633.07 cm . 2920.54/ cm , 3416.88/ cm ,481.33/ cm , 700.89/ cm , and 2851.70/ cm , 2926 cm-1, 2855 cm-1, 1609 cm-1. Anti-in?ammatory activity of ethanolic leaf extract of Plumeria rubra L. showed that the percentage of inhibition 54.57% at 500?g/ml concentration was evidently higher than the lower concentration of 50 ?g/ml (8.23%). The presence of various bioactive compounds justi?es the use of the leaves for various ailments by traditional practitioners.
