摘要
Objective: To explore the pharmacognostical and phytochemical properties of Sargassum wightii.Methods:and fluorescence analysis of the plant were carried out according to the standard procedure recommended in the WHO guidelines. The qualitative microscopy, phytochemical screening, physicochemical evaluation 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 wightii.
