Psidium Guajava Leaves: Phytochemical study and Pharmacognostic evaluation
Abstract
Psidium guajava known as Guava is a medicinal plant belonging to the family Myrtaceae. P. guajava is a well-known traditional medicinal plant used in various indigenous systems of medicine. P. guajava leaves are green to dull green colour with characteristic taste and having ovate-elliptic shape. The chief constituents like essential oil, poly phenols, tannin, pinene, gallic acid, isoflavonoid, catechin, rutin, ascorbic acid, beta carotene, terpenoid and triterpene shows pharmacological importance against several disorders like antibacterial, anti-inflammatory, antispasmodic, diarrhoea, diabeties, colic, cough, pain, high cholesterol, heart disease, cancer and weight loss.The extract of guava leaves also have antimicrobial and antioxidant activity. P. guajava also contain ascorbic acid beneficial for skin and effective against oxidation and act as antioxidant. The present study reveals the pharmacognostical, physicochemical and phytochemical study of leaves P. guajava which are useful in laying down standardization and pharmacopoeial parameters.
