Plan: Careya arborea is a medicinal plant used in Ayurveda and Chinese medicine. The bark, leaves and fruits are used in these systems for the treatment of ulcers, haemorrhoids and tumours. Several reports are available on the pharmacognosy of the leaf and bark of this medicinal tree. However, there is complete lack of information on the pharmacognosy of the fruit. The present paper is the first report on this subject.
Methodology: Histology of the fruit and microscopy of the fruit powder were studied. Tests for identification of phytochemical compound classes were carried out on methanol extract of the fresh fruit. The chemical constitution of the fruits was studied using HPTLC and HPLC.
Outcome: Phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, sterols and fixed oils. The fruit contains high amount of phenols, of which, gallic acid is present at the rate of 0.92 ± 0.03%. The high content of gallic acid and reported antibacterial activities of the extract quality the fruit for further investigations.
Key words: Careya arborea, Pharmacognosy, Gallic acid, HPTLC
