The present report deals with the analysis comparison of the essential oils from aerial parts of Conium maculatum L. growing wild in Iran were obtained by hydrodistillation, microwave assisted hydrodistillation and solid phase microextraction methods and collected essential oils were analyzed by GC and GC-MS. The plant is a member of the Apiaceae family of rhizomal plant which are usually 120-180cm high. C. maculatum which is also called as Poison hemlock is refered to as one of the most toxic plants. The volatiles were isolated from dried aerial parts of the plant. Twenty two compounds were identified representing 73.8% of total volatiles obtained by HD and the major constituents of the essential oil were α-pinene(16.2%), camphene (9.9%), limonen(8.6%) and linalool(5.3%).Sixteen compounds were identified representing 74.6% of total oils obtained by MAHD and the main components were camphene(13.0%) , limonene(8.7%) , linalool(8.4%) and Fenchyl acetate(7.6%) .Nine compounds were identified representing 99.8% of total oils obtained by SPME and the main components were α-pinene(42.1%), sabinene(16.2%0), limonene ( 11.3%),camphene(9.5%) and myrcene(7.9%).DOI: http://dx.doi.org/10.3126/ijls.v9i2.12056 International Journal of Life Sciences 9 (2) : 2015; 48-50

This study was aimed at comparing the essential oils obtained from Heteromorpha arborescens leaves by Solvent-Free Microwave Extraction (SFME) and Hydrodistillation (HD) methods in terms of their chemical compositions, yield, CO2 emission, and energy consumption. The solvent-free microwave extraction method indicated a higher oil yield of 0.7 mL/200 g (0.35%) as compared to 0.59 mL/200 g (0.295%) obtained through hydrodistillation. GC-MS analysis of the oils revealed a total of 52 chemical components from both methods with the presence of 35 (96.52%) and 30 (71.15%) chemical constituents for HD and SFME, respectively. The major constituents observed in the essential oil extracted by SFME methods include α-pinene (6%), D-limonene (11.27%), β-ocimene (9.09%), β-phellandrene (6.33%), β-mycene (8.49%), caryophyllene (5.96%), and camphene (4.28%). However, in the hydrodistillation method, the oil was majorly composed of a-pinene (4.41%), β-pinene (10.68%), β-ocimene (6.30%), germacrene-D (5.09%), humulene (5.55%), and α-elemene (6.18%). The SFME method was better in terms of saving energy (0.25 kWh against 4.2 kWh of energy consumed), reduced CO2 emission (200 g against 3360 g of CO2), a higher yield, and better quality of essential oil due to the presence of higher valuable oxygenated compounds (8.52%) against that of the hydrodistillation method (2.96%). The SFME method is, therefore, a good alternative for extracting the oils of H. arborescens leaves since the essential oil yield is higher with more oxygenated compounds, considerable energy savings, lower cost, and reduced environmental burden at substantially reduced extraction time (30 min as opposed to 180 min).

Method Of Extraction

Till date, no study has ever looked into the effect of extraction method on the chemical constituents of the essential oil of Helichrysum petiolare. This study therefore evaluated the effect of hydrodistillation and solvent free microwave extraction (SFME) methods on the chemical constituents of H. petiolare derived essential oils. The SFME derived essential oil was deep yellow and of higher yield than the pale yellow essential oil obtained through the hydrodistillation. There were substantial amounts of monoterpenes, monoterpene alcohols, sesquiterpenes, and sesquiterpene alcohols in both essential oils obtained. The SFME derived essential oil had 62 compounds as against the 52 derived through hydrodistillation. The SFME derived essential oil can therefore be suggested to be of better quality than of the hydrodistillation method. The compounds obtained in the essential oils have high pharmaceutical and cosmetic values, and as observed in this study, their quantity is dependent on method of extraction.

Abstract Thirty-six compounds were identified from aerial parts of Solidago chilensis cultivated at PAF/FIOCRUZ campus in Rio de Janeiro city (RJ) using solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) analysis. These compounds are mainly non-oxygenated mono and sesquiterpenes. Germacrene D is the major compound of two the essential oil analyzed samples (12 to 23%) and of two of the volatiles samples analyzed by SPME (central stems and dry inflorescences samples). Limonene is the major compound in the fresh inflorescences sample (about 21%). The bornil acetate is present in both volatile fractions (16%) and essential oils (7-8%). All the essential oils samples evaluated shown a great antinociceptive activity, considering the used dose of the samples (1 mg/kg) and the standard substance (50 mg/kg). Solidago chilensis is one of Brazil arnicas and it is a medicinal plant widely used by the brazilian population. Other plants of the genus Solidago are also used in traditional medicine in North America and Europe. This is the first report of SPME analysis from Solidago genus and of the antinociceptive effect from Solidago chilensis essential oil.
