Traditional hydrodistillation (HD), steam distillation extraction (SD), organic solvent extraction (SE), and microwave assisted hydrodistillation (MWHD) techniques were compared and evaluated for their effectiveness in the isolation of essential oil of Melissa officinalis from Algeria. The microwave assisted hydrodistillation technique was optimized in terms of both delivered power and time dur...

Trypanocidal activity was found in the volatile oil of dried Dracocephalum kotschyi. GC-MS analysis determined that the major constituents of the oil were geranial (35.8%), C10H14O (26.6%), limonene (15.8%) and 1,1-dimethoxy decane (14.5%). In order to isolate the unknown biologically active monoterpene, fractionation of the volatile oil was carried out by silica gel column chromatography. The ...

From the whole plant of Dracocephalum kotschyi BOISS., two new monoterpene glycosides (9, 10), together with seven known terpenoids and a phytosterol (1-8), were isolated. Their structures were determined to be limonen-10-al (1), geranial (2), neral (3), beta-sitosterol (4), oleanolic acid (5), ursolic acid (6), p-mentha-8-en-1,2-diol (7), colosolic acid (8), limonen-10-ol 10-O-beta-D-glucopyra...

background and objectives: dracocephalum kotschyi is a plant which belongs to the lamiaceae family and exists mostly in south-west asian countries, including iran. this plant is used as antispasmodic, analgesic and anti-inflammatory to treat rheumatoid diseases. methods: in order to investigate the impact of the harvesting time changes on the quantity and quality of mono- and sesquiterpenoid co...

Lemon oils are amongst the highest volume and most frequently traded of flavor fragrance essential oils. Citronellal citral considered key components responsible for lemon note with (neral + geranial) preferred. Of myriad sources citral, Australian myrtaceous tree, Myrtle, Backhousia citriodora F. Muell. (Myrtaceae), is superior. This review examines history, natural occurrence, cultivation, ta...

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...

Ce-doped MIL-125-NH2 photocatalysts (Ce/TiMOFs) were synthesized by a facile impregnation-coordination method, during which the doped Ce species could not only extend visible-light absorption edge but also provide new reactive sites for promoting charge transfer and selectivity of two-electron O2 reduction. The optimal Ce/TiMOFs-0.010 achieved rate H2O2 yield 2464 μM h-1 g-1 with ∼3.4-fold impr...
