Chemical constituents of Piper betle Linn. (Piperaceae) roots.
Column chromatography of the alcoholic extract of Piper betle roots furnished aristololactam A-II and a new phenyl propene, characterized as 4-allyl resorcinol, while the petroleum-ether extract yielded a diketosteroid, viz. stigmast-4-en-3,6-dione. All these compounds were characterized by spectroscopic means. Isolation of these compounds from this source is being reported here for the first t...
متن کاملPharmacognostical and Phytochemical Studies of Piper Betle Linn Leaf
Objective: The present work has been done to establish various pharmacognostical, physicochemical and phytochemical parameters of the leaf of Piper betle Linn. (Bangla variety) belonging to family Piperaceae. This could serve as a measure of authentication and quality control of the crude drug. Methods: Organoleptic, anatomical, microscopic, physicochemical analysis and preliminary phytochemica...
متن کاملVolatile chemical constituents of Piper aduncum L and Piper gibbilimbum C. DC (Piperaceae) from Papua New Guinea.
Exhaustive hydro-distillation of the leaves of Piper aduncum and fruits of Piper gibbilimbum (Piperaceae) afforded colorless and pale orange colored oils in 0.35 and 0.30 % yields, respectively. Detailed chemical analysis by GC/MS indicated the volatile constituents of Piper aduncum to be composed of dill apiole (43.3%), beta-caryophyllene (8.2%), piperitione (6.7%) and alpha-humulene (5.1%), w...
متن کاملA new hydroxychavicol dimer from the roots of Piper betle.
A new hydroxychavicol dimer, 2-(g'-hydroxychavicol)-hydroxychavicol (1), was isolated from the roots of Piper betle Linn. along with five known compounds, hydroxychavicol (2), aristololactam A II (3), aristololactam B II (4), piperolactam A (5) and cepharadione A (6). The structures of these isolated compounds were elucidated by spectroscopic methods. Compounds 1 and 2 exhibited inhibitory effe...
متن کاملAn Investigation of the Vegetative Anatomy of Piper sarmentosum, and a Comparison with the Anatomy of Piper betle (Piperaceae)
This paper describes the detailed anatomy and micromorphology of the vegetative parts of Piper sarmentosum Roxb. (synonym, P. lolot C.DC.), which is a southeast Asian medicinal plant valued for its medicinal and culinary uses. The study also compares the anatomy of the leaf, petiole, stem and root of P. sarmentosum with those of the well-characterized P. betle L. The leaves of both the species ...
