“…Intermediary extractive yield was detected to EO samples of O. americanum in comparison to previous reports (Lawrence, 1989;Silva et al, 2003;Ngassoum et al, 2004;Vieira & Simon, 2006;Hassane et al, 2011;Nascimento et al, 2011). Their chemical compositions were also distinct from that reported for the same species growing in Brazil, where only E-methyl cinnamate and methylchavicol chemotypes were detected (Silva et al, 2003;Vieira & Simon, 2006;Nascimento et al, 2011).…”

“…The plants of the Ocimum genus (Lamiaceae), collectively called basil, are considered good sources of EO used in food flavoring, oral products, fragrances and traditional medicines (Vieira & Simon, 2006). Recently, anesthetic and sedative effects of the EO of Ocimum gratissimum L. in fish and its potential application in aquaculture have been reported (Benovit et al, 2012;Silva et al, 2012).…”

The aim of this study was to evaluate the anesthetic activity of the essential oil (EO) of Ocimum americanum L. in silver catfish (Rhamdia quelen). In the first experiment, the depressor effects and chemical composition of the leaf EO (LEO) and inflorescence EO (IEO) were compared. Juveniles (n = 10) were placed in aquaria containing different concentrations of EO (25 -500 mg L -1 ) to determine the point at which anesthesia was induced and the length of the recovery period. In the following experiment, the effects of 300 and 500 mg L -1 LEO exposure on stress parameters (plasma cortisol, glucose and sodium levels) after air exposure for 1 min were assayed. Fish (n = 10 per sampling time) were sampled immediately or transferred to anesthetic-free aquaria until sampling (15, 30, 60 or 240 min). LEO was composed mainly of β-linalool and 1,8-cineole in similar proportions, whereas IEO showed β-linalool as major compound. Anesthesia was obtained in silver catfish with 200-500 mg L -1 between 4-8 min for LEO and 6-16 min for IEO. Lower EO concentrations did not reach anesthetic stage up to 30 min. LEO used as anesthetic prevented the cortisol increase and sodium loss induced by aerial exposure. Glucose levels were raised in catfish exposed to LEO compared to basal group (not air exposed) in almost all observation times. EO of O. americanum obtained from leaves was considered suitable to anesthetic procedures due to its fast induction and handling-induced stress prevention.O objetivo deste trabalho foi avaliar a atividade anestésica do óleo essencial (EO) de Ocimum americanum L. em jundiás (Rhamdia quelen). No primeiro experimento, os efeitos depressores e a composição química dos óleos obtidos a partir das folhas (LEO) e das inflorescências (IEO) desta espécie vegetal foram comparados. Para isto, juvenis de jundiás (n = 10) foram transferidos para aquários contendo diferentes concentrações de EO (25 -500 mg L -1 ) a fim de determinar os tempos de indução aos estágios de anestesia e de recuperação. No experimento seguinte foram determinados os efeitos da exposição a 300 e 500 mg L -1 de LEO em parâmetros de estresse (cortisol, glicose e níveis de sódio plasmáticos) após os animais serem expostos durante 1 min ao ar. Os peixes (n = 10 por tempo de amostragem) foram coletados imediatamente ou transferidos para aquários livres de anestésico até amostragem (15, 30, 60 ou 240 min). LEO demonstrou ser composto majoritariamente por β-linalol e 1,8-cineol em proporções similares, enquanto que IEO apresentou β-linalol como constituinte majoritário. O estágio de anestesia foi verificado em jundiás com 200-500 mg L -1 entre 4-8 min para LEO e 6-16 min para IEO. Menores concentrações de ambos os EO não promoveram anesthesia até 30 min. O uso de LEO como anestésico preveniu o aumento de cortisol e a perda de sódio induzida pela exposição aérea. Já a glicemia encontrava-se aumentada em peixes expostos ao LEO em comparação ao grupo basal (não exposto ao ar) na maioria dos tempos de observação. Assim, EO de O. americanum obtido a par...

Ocimum basilicum'red rubin' is highly valued for its essential oil, and is widely used in folk medicine, but few studies examining in vitro propagation techniques for this basil variety are available. We examined the development of red rubin basil seedlings grown in vitro in different concentrations of mineral salts, charcoal combined with sucrose, and potassium iodine in three series of tests. In the first series, five concentrations (0, 25, 50, 75 and 100%) of Murashige and Skoog salts (MS culture medium) were used to germinate sterilized seeds of O. basilicum. In the second test, to evaluate the combined effects of charcoal and sucrose on basil growth, three concentrations of charcoal (0, 3.0, and 4.5 g/L) and two of sucrose (30 and 60 g/L) were used. In the third test, the seeds were sown onto culture medium enriched with five different concentrations of potassium iodine (0, 25, 50, 75 and 100µM); 0.5 μM benzyl aminopurine (BAP) and 1.0 μM naphthalene acetic acid (NAA) were added to all germination media. A completely randomized experimental design was used in all tests, with five replicates, four vials per test, and 4 seeds per vial. In Test 2, seedling oxidation (%) and the numbers of leaves and shoots were submitted to non-parametric analysis using the Kruskal Wallis test (p ≤0.05). The other data were submitted to analysis of variance (p≤0.05). The qualitative means were evaluated by the Tukey test (p≤0.05), and the quantitative means by polynomial regression (p≤0.05). The results showed that 100% MS culture medium was most indicated for 'red rubin' seed germination and aerial portion production, while 70-80% MS was indicated for root production. A sucrose level of 30 g/L (standard) combined with 4.5 g/L of activated charcoal allowed the best seedlings development and inhibited callus formation. Activated charcoal limited copper and zinc uptake by O. basilicum seedlings, but not enough to hamper their development. Increasing concentrations of potassium iodine reduced all of the growth variables analyzed in this basil variety.Keywords: Ocimum basilicum L., micropropagation, medicinal plant, culture medium.

“…The genus Ocimum contains around 30 species native to the tropics and subtropics, with some species naturalized and/or cultivated in temperate areas and includes species used as condiments, sources of essential oils or medicine (Vieira and Simon 2006). Moreover, in particular red varieties of basil are characterized by high contents of anthocyanins.…”

Abstract:Red basil (Ocimum basilicum L.) cv. Red Rubin was cultivated in model pot experiment in the soil amended by arsenic, cadmium and lead solutions in stepwise concentrations representing the soil concentration levels of former mining area in the vicinity of Příbram, Czech Republic. The element levels added to the soil reached up to 40 mg Cd, 100 mg As, and 2000 mg Pb per kg of soil. Moreover, essential macro-and microelements as well as cyanidine contents were investigated to assess their potential interactions with the risk elements. The extractable element portions in soils determined at the end of vegetation period differed according to the individual elements. Whereas the plant-available (extractable with 0.11M CH 3 COOH) content of Cd represented 70-100% of the added Cd, the mobile portion of Pb did not exceed 1%. The risk element content in plants refl ected the increasing element contents in soil. The dominant element portions remained in plant roots indicating the limited translocation ability of risk elements to the aboveground biomass of this plant species. Although the risk element contents in amended plants signifi cantly increased, no visible symptoms of phytotoxicity occurred. However, the effect of enhanced risk element contents on the essential element uptake was assessed. Considering inter-element relationships, elevated sulphur levels were seen in amended plants, indicating its possible role of phytochelatin synthesis in the plants. Moreover, the molybdenum contents in plant biomass dropped down with increasing risk element uptake by plants confi rming As-Mo and Cd-Mo antagonism. The increasing content of cyanidine in the plant biomass confi rmed possible role of anthocyanins in detoxifi cation mechanism of risk element contaminated plants and suggested the importance of anthocyanin pigments for risk element tolerance of plants growing in contaminated areas.
