Bauhinia variegata is a species of flowering plant belonging to the family ‘Fabaceae’, which is native to Southeast Asia, Southern China, Pakistan and India. This is a popular ornamental tree in sub-tropical and tropical climates. Almost all the parts of the tree Bauhinia variegata are used pharmacologically as in obesity, bleeding piles, worms, cough, inflammatory skin diseases, balancing activity of thyroxin production, haematuria, dysuria, anti-ulcer, menorrhagia and goitre and many others.
The objective of the present study was to do a qualitative
evaluation of phytochemicals present in the flower buds of Bauhinia variegata
(BV) which belongs to the family “Fabaceae’ which is well known for its scented
flowers. A few of the Bauhinia variegata trees (6 trees) were spotted in
Universiti Sains Malaysia (U.S.M.), Penang, near the old building of ‘Subaida
Restourant’.
The young, premature flower buds of the plant were subjected
to analysis for their phytochemical constituents as fresh material. The fresh
raw flower buds of the plant were macerated and subjected to hot percolation
separately. The maceration was carried out for 72 hours with absolute alcohol.
The hot percolation (Soxhlet extraction) was carried out in intervals,
approximately for 40 hours. The shade-dried flower buds were also subjected to
maceration and hot percolation separately with absolute alcohol. The extracts
were dried over a rotary evaporator. After evaporation, the greenish pinkish
colour gummy mass was obtained from the fresh flower bud extractions. The
evaporated extracts of shade-dried flower buds were of a greenish gummy mass.
Some of the extracts were greenish yellow and greenish in colour. All
evaporated extracts were dissolved and diluted in the respective solvents for
phytochemical analysis. The qualitative screening of analytical results showed
the presence of alkaloids, reducing sugars, terpenoids, glycosides, tannins,
flavonoids and carbohydrates in all the extractions. The tests for saponins
revealed that this group was not present in any of the solvent extracts.
Anthraquinones showed the presence in Flower A and Bud SA only, while this
group was not present in Flower B, Bud A and Bud B samples. Antioxidant
activity was also determined, showing highly antioxidant activity.
These findings highlight the therapeutic potential of
Bauhinia variegata flower buds, and further studies are required to validate
these results.
