Kshitij Agarwal* and Anurekha Jain

Abstract

Pterygota alata (Roxb.) R. Br., family: Sterculiaceae is a tall evergreen tree, commonly known as Buddha Coconut in English, Tula in Bengali and Kodaittondi in Tamil, found in India and South East Asia. Seeds are edible and the oil obtained from the seed is nutritious. It is used as the substitute of Opium. The present study was carried out to establish physico-chemical parameters along with preliminary phytochemical screening of petroleum ether, chloroform, methanolic and aqueous extracts of Pterygota alata. Preliminary phytochemical screening of various extracts revealed the presence of carbohydrate, flavonoids sterols, phenolic & tannins compounds. The physico-chemical parameters such as total, water soluble, acid insoluble and sulphated ash (7.01, 5.65, 0.52 and 1.95%w/w respectively) and loss on drying (8.17 %w/w), extractive values foaming and swelling index were studied. These studies will be helpful in developing standards for quality, purity and sample identification of this plant.

Keywords: Standardization, Pterygota Alata, Physicochemical and Phytochemical.
