Thyme, mint, and lemon balm were used to determine whether shading conditions could improve the yield, composition, antioxidant, antimicrobial activity in plant essential oils (EOs) comparison with non-shaded plants from an open field. The yield of EOs thyme, balm, was 3.44, 3.96, 0.21 mL/100 g, respectively. Plants covered by nets produced different levels (3.46, 2.20, 0.45 g) after 120 min hy...

The objective of this work is to develop a novel coacervation process to produce microcapsules of polylactide (PLA) to encapsulate thyme oil that will be used in cosmetics. The novelty of this approach consists of dissolving PLA in dimethylformamide (DMF) which is a good solvent for PLA but in addition has high solubility in water. Upon contact with water, the homogeneous solution of PLA in DMF...

conclusions the excellent antimicrobial activities of the tested eos might be due to their major phenolic or alcoholic monoterpenes with known antimicrobial activities. hence, these eos can be possibly used as an antimicrobial agent in treatment and control of oral pathogens. results the tested eos inhibited the growth of examined oral pathogens at concentrations of 0.015-16 µl/ml. among the ex...

Thymus serpyllum L. grown in Kumaon region of Western Himalaya was investigated for essential oil content and composition in different seasons. The oils of fresh samples were obtained by hydrodistillation. The yield of essential oil (% v/w) during different seasons varied from 0.07 to 0.28% with the highest in summer season, at vegetative stage. The oils were analyzed by GC and GC-MS. Major com...
