Antimicrobial films of poly (lactic acid) (PLA)/D-limonene/zinc oxide (ZnO)-based bio-nanocomposites were prepared via melt compounding and subsequent thermocompression. D-limonene was incorporated at concentrations 10 or 20 wt%, ZnO pure nanoparticles those organically modified with oleic acid (O-ZnO), an average diameter 13.5 nm, included 3, 5, 8 wt%. The plasticizing effect D-Limonene corrob...

background: achillea tenuifolia lam. (compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. it has been used to reduce sweating and to stop bleeding. it helps regulation of the menstrual cycle and reduces heavy bleeding and pain. materials and methods: plant material (flower, leaf and stem) was collected in k...

the effect of ph, different concentration of tween 80 and calcium ion on the stability of limonene-in-water emulsions stabilized by various concentration of sodium caseinate (2, 5 and 10%) was evaluated. to this end, emulsions were prepared by ultrasound and their quality attributes including size distribution, mean diameter of droplets, specific surface area and span number were studied as a r...

ABSTRACT: Due to the importance of essential oils and their use in various industries, the essential oils of four types of citrus consisting of orange (C. sinesis), tangerine (C. reticulate), sweet lemon (C. limetta) and sour lemon (C. limon) were extracted and subjected to chemical analysis to identify and evaluate the chemical constituents of the oils. The average essential oils of orange, ta...

Dracocephalum kotschyi (Lamiaceae), as one of the remarkable aromatic plants, widely grows and also is cultivated in various temperate regions of Iran. There are diverse reports about the composition of the oil of this plant representing limonene derivatives as its major compounds. There is no report on cloning of mono- or sesquiterpene synthases from this plant. In the present study, ...

Microencapsulation facilitates incorporating bioactive volatile compounds into products throughout the food, health, and cosmetics industries. To minimize number of ingredients when microencapsulating oils, we examined surfactant-free encapsulation d-limonene in cross-linked alginate microcapsules (CLAMs) via situ cross-linking during spray drying. Surfactant-free CLAMs (SF-CLAMs) were prepared...

Monoterpenes can, upon hydrogenation, be used as light-fraction components of sustainable aviation fuels. Fermentative production of monoterpenes in engineered microorganisms, such as Saccharomyces cerevisiae, has gained attention as a potential route to deliver these next-generation fuels from renewable biomass. However, end product toxicity presents a formidable problem for microbial synthesi...
