PHARMACOGNOSTIC STUDIES OF STEM TUBER ON BRASSICA OLERACEA VAR. GONGYLODES
Journal Title: International Journal of Pharmacognosy - Year 2016, Vol 3, Issue 5
Abstract
The crude extracts from stem tuber and leaf of Brassica oleracea var. gongylodes in different solvents, were subjected to physico-chemical, fluorescence analysis, phytochemical and antimicrobial study. The microscopic analysis revealed that B. oleracea showed stone cells and calcium oxalate prisms. The ash value was high 7.88 % in B. Oleracea. The fluorescent analysis at 366 nm of B. oleracea under ultraviolet light revealed that powder extracted with alcohol showed pale blue coloured fluorescence, with water showed yellow colour, 0.1 N Sodium hydroxide showed pale yellow and dilute hydrochloric acid had greenish yellow. The extraction value with different solvents exhibited that B. oleracea maximum extractive value with chloroform followed by benzene, ethanol and petroleum ether. The phytochemical screening of the various extract of B. oleracea revealed the presence of alkaloids, flavonoids, resins, saponins and tannins. Anti-bacterial screening in B. oleracea using stem revealed that the ethanol solvent showed maximum inhibition against gram-positive bacteria (Staphylococcus aureus) and chloroform solvent showed maximum inhibition in case of gram-negative bacteria (Serratia marcescence).
