Lemon balm ( Melissa officinalis L.) is a perennial plant of the family Lamiaceae, which used in folk medicine and food industry, as well being processed to obtain essential oil. The aim special work monitor influence vegetation on composition chemical oils, obtained by steam distillation from lemon cultivated North-eastern Bulgaria, has been determined. plants were harvested two periods - firs...

Novel strategies are necessary to improve chemotherapy response in advanced and recurrent endometrial cancer. Here, we demonstrate that terpenoids present in the Steam Distilled Extract of Ginger (SDGE) are potent inhibitors of proliferation of endometrial cancer cells. SDGE, isolated from six different batches of ginger rhizomes, consistently inhibited proliferation of the endometrial cancer c...

The orange-yellow and colorless essential oils with respective yields of 1.54% 3.59% were extracted from the dry leaves Cymbopogoncitratus (DC.) Stapf Eucalyptus citriodora Hook. collected south Brazzaville. Analysis by gas chromatography (GC) coupled mass spectrometry (GC/MS) allowed identification fifteen (15) eight (8) constituents representing (96.25%) (98.46%) total respectively. oil consi...

This study investigates the seasonal variation of three species of Leptospermum (Myrtaceae) grown in Brazil. The chemical composition of the volatile oils of L. flavescens and L. petersonii did not show any significant seasonal variation in the major components, while for Leptospermum madidum subsp. sativum the levels of major constituents of the volatile oils varied with the harvest season. Ma...

The aim of this study is to develop a microemulsion product from a plant essential oil having the highest anti-tyrosinase activity. The in vitro anti-tyrosinase activity of six essential oils extracted from six edible plants was compared. The oil of Cymbopogon citratus demonstrated the highest activity which was significantly nontoxic to normal human cells. The GC-MS data indicated that gerania...

The volatile secondary metabolites of essential oils from fruit peel and leaves of variegated pink-fleshed lemon (Citrus x limon) were investigated using GLC and GLC-MS (gas-liquid chromatography-mass spectroscopy). Altogether 141 compounds were identified and quantified, accounting for 99.59% and 96.33% of the total hydrodistilled peel and leaf oil, respectively. Limonene occurred in higher am...

Litsea cubeba (Lour.) Pers. is a promising industrial crop with fruits rich in essential oils. The chemical composition of essential oils of L. cubeba (EOLC) were determined for fruits harvested from eight regions in China. The overall essential oil content, obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS), ranged from 3.04% to 4.56%. In total, 59 compo...
