“…No significant differences were observed in the yields between essential oils from the bark or leaves with respect to the period of collection, but the yield of the essential oil from leaves was higher than the bark in the dry and rainy season. These results are similar to the reported for essential oil from Caesalpinia echinata, another Leguminosae species [23]. Table 1 shows the composition of the essential oil from bark and leaves of I. laurina in the dry season.…”

“…These fatty acids were not observed in the bark's oil obtained in the dry season and they did not result from the degradation of the esters present in it (Table 1). Palmitic (19,25.40%), lauric (20,5.80%), oleic (21, 5.52%), myristic (22, 4.06%) and linoleic (23,3.58%) were the major fatty acids identified. The terpenoids represented 26.63% and were present in equivalent percentage (30.05%) when compared to the essential oil of the dry season (Tables 2 and 4).…”

Abstract:The seasonal chemical composition of essential oils from Inga laurina was determined by GC/MS. In the stem bark's essential oil extracted during the dry season, the presence of terpenoids (30.05%) stood out, and phytol (9.76%) was the major compound identified. For the stem bark oil obtained during the rainy season, in addition to terpenoids (26.63%), a large amount of fatty acids (46.84%) were identified, in particular palmitic acid (25.40%). Regarding the leaves' essential oil obtained in the dry season, esters (42.35%) were the main components. The main ester present was (Z)-hex-3-enyl benzoate (10.15%) and the major compound of this oil was (Z)-hex-3-en-1-ol (14.23%). Terpenoids for aerobic bacteria, and high selectivity against bacteria was observed. The large amount of fatty acids in rainy season oils may be related to the better inhibitory effects observed.

Terpenes and aroma volatiles from flowers of Calendula officinalis cultivated in southeastern Brazil were obtained by steam distillation (SD), headspace-cold finger (HS-CF) extraction and headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography and mass spectrometric analysis. The dried flowers contained 0.1% oil. Kovats indices and mass spectra were used to identify 27 individual components in the various volatile fractions. The main components present in the volatile fractions of the C. officinalis flowers, obtained by SD, HS-SPME, and HS- CF, 22.1, 25.4, and 24.9 %) while 20.4 % of α-cadinol was seen only after SD extraction.

“…The ex vitro and in vitro plantlets fresh aerial parts, 100 g each, were submitted to hydrodistillation for 1.40 hour, in a Clevenger-type apparatus 6 in replicate (n = 2). The time between the isolation and analysis was the same in all experiments to preclude differences in composition due to external factors.…”

Foram investigados os efeitos de ácido indol acético (11,42 μmol L -1 ) e benzilaminopurina (8,87 μmol L -1 ) sobre o crescimento e composição do óleo essencial de plantas in vitro de Melissa officinalis. Plantas desenvolvidas em meio de Murashige e Skoog (MS) apresentaram o incremento de 1,4 vezes na proporção de nerol e de 4,1vezes de geraniol, quando comparadas às plantas ex vitro. Tratamentos com 11,42 μmol L -1 de ácido indol acético mais 8,87 μmol L -1 de benzilaminopurina resultaram em aumentos de 1,7 e 2,2 vezes na proporção de nerol e geraniol, respectivamente, em plantas de 60 dias. Estes aumentos podem estar associados à ação dos reguladores de crescimento, por estimularem o desenvolvimento vegetal (na organogênese e alongamento de brotos) e retardarem a oxidação de álcoois em aldeídos.It was investigated the effects of indole-3-acetic acid (11.42 μmol L -1 ), benzylaminopurine (8.87 μmol L -1 ) on essential oil composition and on the growth of Melissa officinalis in vitro plants. In vitro plantlets developed on MS media, showed 1.4 times in the proportion of nerol and 4.1 of geraniol, when compared with ex vitro plants. Treatments with 11.42 μmol L -1 indole-3-acetic acid plus 8.87 μmol L -1 benzylaminopurine led to 1.7 and 2.2 fold in proportion of nerol and geraniol, respectively in 60-day-old whole plants. These increases might be associated with the action of growth regulators wich stimulate plant growth (shoot organogenesis and elongation) and delaying the alcohol oxidation to aldehydes. Keywords: Melissa officinalis, essential oil composition, VOCs, GC/MS, growth regulators, tissue culture IntroductionMelissa officinalis Lam. (Lamiaceae) also known as lemon balm, is a perennial herb that presents a lemon flavor. The infusion of its leaves is used in folk medicine due to its sedative and antispasmodic properties. The chemical composition of the essential oil of the M. officinalis leaf (0.02-0.3% dry weight) has been previously studied, being the major compounds citronellal (2-40%) and citral (mixture of neral and geranial: 10-30%), followed by β-caryophyllene, germacrene D, ocimene and citronellol. 1 The growth of sprouts and roots and the composition of the essential leaf oil can be altered by addition of selected phytohormones into the nutrition medium. 2 Culture media supplemented with high concentrations of BA induced Melissa officinalis plants to accumulate more than 10% alloaromadendrene. 3 In order to identify possible factors affecting the oil production and its quality, M. officinalis was cultured in vitro and the effect of growth regulators on the essential oil yield and composition were evaluated by gas chromatography and gas chromatography/mass spectrometry. Experimental Plant materialSeeds acquired from ISLAR, batch Nº 8250 were used to obtain the plant material. Erika Von Sohsten Medeiros Treatment with growth regulatorsNodal segments of in vitro plantlets were cultured in four different media composition: MS0; MS plus 11.42 μmol L -1 Indole-3-acetic acid (IAA); MS plus 8.87 μmol ...
