Abstract
The study investigated the phytochemical and essential oil compositions of Piper umbellatum Linn leaves. The leaves were detached from the stalk and washed carefully under running tap water, air dried at room temperature (20-25 ) for 14 days. The dried leaves were ground into a fine powder using a grinding mill. Phytochemical and essential oils composition were analyzed using GC/MS. Phytochemical composition revealed higher concentrations of phenolic acids (434.95164 mg/100 g), tannin (326.79716 mg/100 g), flavonoids (263.37233 mg/100 g), and stilbenes (144.63450 mg/100 g). Essential oil composition revealed a total of forty compounds of which alpha-pinene (28.09%), beta-pinene (17.73%), beta-caryophyllene (15.21%), Nerolidol (11.72%), and Germacrene D (10.14%) were present in considerable amount. P. umbellatum Linn leaves are therefore rich in bioactive components that possess a wide range of biological activities.
