Several species of the genus Hyptis have presented medicinal characteristics and are frequently indicated to treat gastro intestinal infections, gramps and pain, as well as for skin infections. Three harvests were carried out using six H. pectinata accessions, and the following characteristics were evaluated: plant height, canopy diameter, leave length (L) and width (W), L/W relation and dry weight of leaves and stem. The accession SAM006 have presented highest leave dry matter yield when the three harvests were summed. The aqueous leaf extracts of the same six H. pectinata accessions were tested for anti-edematogenic effect using the carrageenininduced rat paw edema at doses of 200, 400 and 600 mg/kg. The extracts administered orally had a signifi cant anti-edematogenic effect. The dose of 200 mg/kg of accessions SAM004 and SAM005 had a stronger effect reducing the edema by 19.6% and 15.4%, respectively. Similar results were obtained using higher dosages of the aqueous extract of the accessions SAM002, SAM003 and SAM006. It can be concluded that the accessions SAM004, SAM005 and SAM006 are promising genotypes for a plant breeding program that aims the development of a cultivar with highest leave yielding and anti-edematogenic effect.

“…Na caracterização de acessos de manjericão, realizada por Blank et al (2004), o acesso PI 197442 apresentou teor de óleo essencial de 2,54%, antes do programa de melhoramento. No melhoramento com manjericão tipo limão, foram obtidos teores de óleo essencial de 1,5 e 0,7%, nas cultivares Mrs. Burns e Sweet Dani, respectivamente (Morales & Simon, 1997).…”

'Maria Bonita' é proveniente do acesso PI 197442, do Banco de Germoplasma North Central Regional PI Station, EUA. É uma cultivar de manjericão de copa arredondada, pétalas róseas e sépalas roxas, indicada para o Nordeste brasileiro. Apresenta hábito de crescimento ereto, o que favorece a colheita manual e mecanizada. A produtividade média de matéria seca de folhas e inflorescências foi de 20,97 g por planta, 26,34% superior à testemunha 'Genovese'. Possui teor de 4,96% de óleo essencial, e rendimento de 1,18 mL por planta. Seu componente principal é o linalol (78,12%). Seu óleo essencial possui atividades antinociceptiva e antigiardial.

“…These oils have been used in applications in the pharmaceutical, cosmetic and food industries (Vani et al, 2009). The main components of essential oils in Ocimum species are estragol, eugenol, methyl eugenol, citral, linalool, geraniol and thymol (Blank et al, 2004;Khalid, 2006;Vani et al, 2009). Some of these compounds have antibacterial (Stefan et al, 2013;Sneha andSastry, 2011), insecticidal (De Paula et al, 2004) and antioxidant properties (Kaurinovic et al, 2011).…”

Mechanisms by which plants acclimatize to water deficit conditions can affect development and, especially in aromatic plants, the essential oil synthesis. To evaluate the effects of water deficit on Ocimum africanum, seedlings were exposed to water levels corresponding to 100, 80, 70 and 60% of the substrate field capacity. The different watering regimes corresponded to predawn water potentials of -0.5, -0.9, -1.6 and -1.9 MPa, respectively. Decreased stomatal conductance and increased glandular and tector trichome density were observed under water deficit. In addition, reductions in leaf gas exchange and water consumption under water deficit led to decreased plant height, numbers of leaves and inflorescences, and total biomass production. As a result, lower essential oil yield and water use efficiency for biomass production occurred in the -1.9 MPa treatment. The content and production efficiency of essential oil (quantity of oil produced per unit water consumed) were higher in the -0.9 and -1.6 MPa treatments. There were no significant differences among treatments in the chemical composition of essential oil, and the major component of essential oil in leaves and inflorescences was isoeugenol in all treatments. The 80% field capacity watering regime (branch water potential of -0.9 MPa) was best for the growth and production of essential oil in O. africanum, for the cultivation of aromatic plant under drought economically viable in the semi-arid climatic regions.
