Recebido para publicação em 18/12/2008 Aceito para publicação em 20/11/2009 RESUMO: O potencial hidrogeniônico (pH) do solo é um parâmetro que indica o nível de acidez ou alcalinidade do mesmo. Sabe-se que as plantas respondem de diferentes maneiras às mudanças no pH dos solos. Poucos artigos relacionam o crescimento e produtividade de plantas medicinais à variação do pH dos solos. O objetivo deste experimento foi avaliar o efeito de diferentes potenciais hidrogeniônicos, em solo Latossolo Vermelho Distroférrico, no crescimento e produção de sálvia. Com o auxílio de curva de neutralização da acidez do solo foram aplicadas diferentes doses de CaCO 3 para atingir pH de 4,5; 5,0; 5,5; 6,0 e 6,5. O experimento foi conduzido em casa de vegetação durante 18 meses, perfazendo as fases de semeadura, transplantio e três cortes. Os parâmetros avaliados foram altura de plantas, massa seca de folhas, raízes e da parte aérea (soma das massas secas das folhas, ramos e caule), área foliar e volume das raízes. O crescimento e produção das plantas de sálvia foram diretamente afetados com a variação do pH do solo. A manutenção de pH > 5,0 foi suficiente para aumentar significativamente a área foliar, a massa seca das folhas e da parte área das plantas de sálvia em 52,2%, 60,5% e 42,4%, respectivamente, e não afetou o desenvolvimento das raízes de sálvia cultivadas em solos com diferentes pHs.

The soil potential of hydrogen (pH) is a parameter that indicates the acidity or alkalinity level. Plants are known to react differently to changes in the soil pH. Few studies have related growth and productivity of medicinal plants to the soil pH variation. The aim of this experiment was to evaluate the effect of different potentials of hydrogen in Oxisol on sage growth and producti vity. With the aid of a soil acidity neutralization curve, different CaCO 3 levels were applied to reach pH values of 4.5, 5.0, 5.5, 6.0 and 6.5. The experiment was carried out in a greenhouse during 18 months, covering sowing, transplanting and three-pruning phases. Plant height, leaf, root and shoot dry matter (sum of leaf, branch and stem dry matter), leaf area and root volume were evaluated. Sage growth and productivity were directly affected by the soil pH variation. The maintenance of pH > 5.0 was enough to significantly increase leaf area, and leaf and shoot dry matter of sage plants at 52.2%, 60.5% and 42.4%, respectively, and did not affect root development of sage plants grown in soils presenting different pH levels.

Chemical composition of sage (Salvia officinalis L.) essential oil from the Rio de Janeiro State (Brazil)

“…Its chemical composition is characterized by high amounts of α-thujone, camphor, β-pinene and α-pinene, and is similar to those found in the oils from Italy (Veličkovic et al 2003), Romania (Veličkovic et al 2003;Radulescu et al 2004), Serbia and Montenegro (Couladis et al 2002;Mitić-Culafić et al 2005), Brazil (Pierozan et al 2009) and Turkey (Karaaslan & Özguven, 2001).…”

“…Salvia officinalis or sage (Lamiaceae family) is a perennial low shrub native of the Mediterranean region and its family reported to include more than 900 species (Pierozan et al 2009;Ilkiu-Vidal et al 2010). Its essential oil is added to meat, sausage, poultry stuffings, fish, soups, canned foods and other food products.…”

Antioxidant Activity and Biological Studies of Two Medicinal Plant Extracts on Spodoptera littoralis (Boisd)

“…Sage (Lamiaceae family) is a perennial low shrub native of the Mediterranean region and its family reported to include more than 900 species (Pierozan, et al 2009;Ilkiu-Vidal, et al 2010) Its essential oil is added to meat, sausage, poultry stuffing, fish, soups, canned foods and other food products. Sage essential oil protected liver pates from oxidation processes and could be used as an alternative option to synthetic antioxidants such BHT and was used in dry fermented buffalo sausage too (Estévez, et al 2007;Salem & Ibrahim, 2010) Thyme (Lamiaceae family) is herbaceous plant of the platoon species, grows in mountainous areas, used as a beverage instead of or with tea, added to some food to give it an acceptable flavor, the plant is used in folk medicine frequently where it is prescribed to treat mouth infections, stomach, intestine and airways, coughing and gastroenteritis and expel intestinal worms, as well as to strengthen the heart (Mohamed, et al2013).…”

“…A sálvia (Salvia officinalis L.), conhecida popularmente como salva, salva-dasboticas ou salva-dos-jardins, é uma espécie da família Lamiaceae (Labiateae), originária da região meridional da Europa. Apresenta hábito de crescimento herbáceo ou arbustivo de pequeno porte, é planta perene que floresce no Hemisfério Sul entre os meses de agosto e dezembro [58] .…”
