*Dr. Deshpande S. N.

ABSTRACT

Psidium guajava L.commonly known as gauva has medicinal importance. The present study was carried out for the investigation of chemical compounds found in Psidium guajava L. by simple chemical tests and by GCMS analytical method. The extracts were prepared by using methanol and chloroform as solvents by Soxhlet method. The preliminary phytochemical analysis revealed the presence of Alkaloids, carbohydrates, tannins, proteins, saponins, fixed oils & fats, cardiac glycosides in both extracts however amino acids, anthraquinones & flavonoids were absent in the extracts of Psidium guajava (Linn) leaves. GCMS analysis of the methanol extract of leaf of Psidium guajava L. revealed the presence of sixteen compounds. The major compound was Caryophyllene with 71.07% peak area followed by 6,10-Dodecatrien-3ol,3,7,11trimethyl-[E]- and Napthalene1,2,3,4 tetrahydro- 1,6dimethyl-4-1-(methyl ethyl)-(1 S-cis)-. The Chloroform Extract extract of Psidium guajava L. showed the presence of eight compounds. Caryophyllene was found as the major [71.07%] compound followed by Caryophyllene oxide [37.02%].
