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.
