Pharmacognostical study and phytochemical evaluation of brown seaweed Sargassum wightii
Objective: To explore the pharmacognostical and phytochemical properties of Sargassum wightii.
Methods: The qualitative microscopy, phytochemical screening, physicochemical evaluation
and fluorescence analysis of the plant were carried out according to the standard procedure
recommended in the WHO guidelines.
Results: Macroscopic study showed that plants were dark brown, 20-30 cm in height, leaves were
5-8 cm length, shape: linear to ovate, apex: midrib in conspicuous and having the entire, serrate
margin. Microscopic evaluation of the transverse section of the leaf, stem, air bladder, receptacles
showed the presence of epidermis layer followed by thick cuticle, conducting strand, mesophyll
and possessed antheridia or oogonia at the swollen terminal portions. The different extracts of
Sargassum wightii showed the presence of steroids, alkaloids, phenolic compounds, saponins and
flavonoids with varied degree.
Conclusions: Various pharmacognostical parameters evaluated in this study help in the
identification and standardization of the of the seaweed Sargassum wighti
