Abstract:
Lamiaceae is a quite large vegetal family, containing approximately 220 genera and about 3500-4000 species. The genus Ocimum is belonging to this family and is represented by about 160 species, native to the tropics and subtropics, and some are found in temperate regions, usually propagated by seeds. The species Ocimum selloi Benth is native to Brazil, popularly known as basil and used as anti-diarrheal, anti-spasmodic, anti-inflammatory activity and has proven insect repellent. The aim of this study was analyze the constituents of essential oil and methanol extract of leaves of Ocimum selloi Benth. The plant material was collected in the city of Nova Floresta - PB. The essential oil samples were extracted by the steam distillation method modified in Clevenger apparatus and analyzed by GC / MS. The methanol extract of the leaves was also prepared and analyzed by HPLC. The major component of the essential oils was estragole, ranging from 67.95% to 78.85%, setting the studied specie as belonging to chemotype metilchavicol. The subsequent major components were eucalyptol (7.08 - 8.98%), terpinen-4-ol (2.42 - 3.38%) and α-bergamotene (1.57 - 2.48%), their income were corresponding to those described in the literature and were found to vary in content and components by comparing samples from different seasons. The analysis of the methanol extract showed the presence of caffeic acid, chlorogenic acid, rutin and taxifolin, phenolic substances with pharmacological potential.
