The present study deals with the qualitative and quantitative analysis of phytochemical and proximate analysis of seed extract of two different germplasms of Mucuna black and white colored seeds (BCS & WCS) were investigated. Between the two seeds studied, the black colored seed which is in raw form registered higher efficiency in proximate composition as well as phytochemical when compared to white colored seeds. This consequence has followed the same in both cooked and soaked & cooking process of Mucuna seeds. Further, mechanistic studies on pharmacological evaluation are needed for commercial exploitation of these legumes as...

The crude extracts from stem tuber and leaf of Brassica oleracea var. gongylodes in different solvents, were subjected to physicochemical, 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 colored fluorescence, with water showed yellow color, 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 the case of gram-negative bacteria (Serratia...

Polygonum flaccidum (Polygonaceae) is an annual herb widely distributed in Bangladesh, India, Bhutan, Sri Lanka, and Afghanistan. Objectives of the present study were to determine antioxidant, anthelmintic, cytotoxic, insecticidal and antibacterial activities of methanol extract of P. flaccidum. Antioxidant activity in terms of free radical scavenging ability was determined by DPPH free radical scavenging assay. Cytotoxic activity was performed by brine shrimp (Artemia salina) lethality bioassay. Anthelmintic efficacy was determined using adult Bangladeshi earthworm. Insecticidal activity was tested against rice weevil Sitophilus oryzae. Antibacterial activity was tested by the disc diffusion method. The extract exhibited significant antioxidant activity by scavenging DPPH free radical. The IC50 value of the extract displayed 4.91μg/ml while standard ascorbic acid showed 2.69 μg/ml. The extract exhibited potent anthelmintic activity by causing paralysis (30 min) and death (45 min) of worms and the effect was found to be dose-dependent. In an insecticidal study, the lethal effect of methanol extract on Sitophilus oryzae was found to be dose-dependent manner. In cytotoxicity study, LC50 value of the...

Lippia is a genus of flowering plants belonging to the Verbenaceae family. It contains about 220 species with diverse ethnopharmacological applications. Myriad of biologically active phytoconstituents abound in Lippia. The essential oil chemotypes found in Lippia species included myrcenone rich-type, carvone rich-type, piperitenone rich-type, ipsenone rich-type, linalool rich-type, citral rich-type, carvacrol rich-type, thymol rich-type and lippiol rich-type. Other constituents apart from essential oils isolated and chemically characterized were highlighted. β-caryophyllene and iridoid glycosides were notable as chemotaxonomic marker compounds which were common to many of Lippia...
