Antioxidant capacity of crude water and ethyl acetate extracts of some Indian spices and their antimicrobial activity against Vibrio vulnificus and Micrococcus luteus

The water and ethyl acetate extracts of six Indian spices were screened to identify their antioxidant activity and antimicrobial properties against Vibrio vulnificus and Micrococcus luteus. The 2,2’-Diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) and total phenolic compounds (TPC) assay were used for determining antioxidant activity. The ethyl acetate spice extracts...

Genetic association, divergence and variability studies for seed yield and oil content and its contributing traits in Jatropha (Jatropha curcas L.)

Genetic association, divergence and variability were studied in 24 accessions of Jatropha curcas L. for seed and oil yield and its contributing traits. Based on genetic divergence D2statistics, 24 accessions were grouped into 14 clusters. Three accessions (BRS-12/05-UpA2, BRS-12/05-UpA3 and BRS-03/06-WbB) were included in cluster XI followed by clusters II, IV, VI, VII, VIII, X, XII and XIII (2 accessions in...

1, 8-Cineole: A predominant component in the essential oil of large cardamom (Amomum subulatum Roxb.)

Oil obtained by hydro-distillation of the dried capsules of large cardamom (Amomum subulatum Roxb.) grown in Uttarakhand, India was analyzed by GC-MS. A total 18 components representing 99.21% of the total oil contents were identified by mass spectra and relative retention indices. The predominant constituents of the oil were found to be 1, 8-cineole (73.27%) followed by α-terpineol (4.23%),...
