the lamiaceae family consists of a broad spectrum of medicinal plants involving marrubium l. genus. regarding the diverse pharmaceutical uses of the plants belonging to this genus, they can be considered as proper alternatives for chemical drugs having harmful effects. the present work aims to identify and characterize chemical compositions of the essential oils and volatiles from the aerial pa...

the water-distilled essential oils, which were obtained from the fresh aerial parts of satureja hortensis were analyzed by means of gc and cc/ms instruments. the plant was collected during the flowering stage from foroomad mountains, semnan province, and heart of iran. twenty compounds were identified in the different samples analyzed, representing 100% of the total oil contents. in terms of ge...

Pogostemon cablin Benth. var ‘Sidikalang’ leaves are the main source of patchouli oil which is used in cosmetics and perfume industry because its better fixative nature provides foreign exchange around 60 % Indonesia’s essential export revenues largest supplier world with a contribution 90 %. But apparently, several studies found that also has pharmacological activity such as aromatherapy, anti...

as traditional extraction methods like hydrodistillation (hd) and steamdistillation (sd) have long extraction times, some novel extraction methods like microwave-assisted hydrodistillation (mahd) and ohmic-assisted hydrodistillation (oahd) are recently introduced. in this study, essential oils of mentha piperita were extracted by oahd and mahd and the results were compared with those of the sd ...

Two different extraction methods were used for a comparative study of algerian myrtle leaf essential oils: solvent-free-microwave-extraction (SFME) and conventional hydrodistillation (HD). Essential oils analyzed by GC and GC-MS presented 51 components constituting 97.71 and 97.39% of the total oils, respectively. Solvent-Free-Microwave-Extract Essential oils SFME-EO were richer in oxygenated c...

The present study aimed to investigate the physicochemical and energy characteristics of Pinus nigra Arn. (Pinaceae family) coniferous biomass used after production essential oil. biomass, comprised needles with twigs, was milled subjected sieve analysis, thus producing three groups particle fractions (between 384 413 μm). infrared spectrum recorded as 4000–400 сm–1. results from revealed signi...
