To analyze and extract phylogenetic information from chemical characters, the 3b-hydroxysterol composition of 12 sponge species of various families of the Poriferan order Halichondrida (sensu lato), was determined. The current definition of the order is ambiguous, and its classification remains in a state of flux and hence, further chemical characters may aid in stabilizing it. Axinella corruga...

The macroscopic characters of the whole plant, physical constant values, extractive values, preliminary phyto-chemical tests, fluorescence characters under ultra-violet light after treatment with different reagents of the powdered leaves form the tree of Adansonia digitata linn., [Bombacaceae] were studied to fix some pharmacognostical parameters. Preliminary phytochemical screening on the meth...

The macroscopic characters of the whole plant, physical constant values, extractive values, behavior on treatment with different chemical reagents, fluorescence characters under ultra violet light after treatment with different reagents of the powered entire plant of Cleome viscose Linn.(Capparidaceae) were studied to fix some pharmacognostical parameters. Preliminary phytochemical screening on...

The macroscopic character of the leaves, physical constant values, extractive values, behavior on treatment with different chemical reagents. Fluorescence characters under ultraviolet light after treatment wit different chemical reagents of the powdered leaves of Cassia tora Linn. (Family: Leguminosae) were studied to characterize some pharmacognostical parameters. Preliminary phytochemical stu...

The macroscopic characters of L. lavandulaefolia, physical constant values, behaviour on treatment with different chemical reagents, fluorescence characteristics after treatment with different chemical reagents of the powder of L. Lavandulaefolia were studied to fix some pharmacognostical parameters. Preliminary phytochemical studies and TLC characterization of different extractives has also be...
