Thymus hyemalis L. and Spanish Thymus vulgaris L. shrubs are characterized by a large chemical intraspecific variability among he plants. This fact makes it difficult to detect real changes occurring in their essential oil composition during the vegetative cycle. ased on this, the clones of T. hyemalis and Spanish T. vulgaris were used in this present work to monitor seasonal variations in the ...

The volatile compounds from various parts of Echinops ilicifolius (Compositae) such as flowers, leaves and roots obtained by hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) methods were subsequently analysed by GC and GC/MS and compared. Thirty-seven and 20 components of the flower of E. ilicifolius were characterized, representing 99.7% and 100.0% of the total compos...

the composition of the essential oils of two african (“white” and “yellow”) olibanums available in the commercial market of isfahan (iran) was analyzed by gas chromatography (gc) and gc-mass spectroscopy methods. the main constituents of the “white” olibanum oil were alpha-pinene (34.8%), limonene (15.9%), alphathujene (9.0%), para-cymene (7.0%), myrcene (6.2%) and sabinene (6.0%). major compon...

The highly porous and robust [Ni(8)(OH)(4)(OH(2))(2)(4,4'-(buta-1,3-diyne-1,4-diyl)bispyrazolato)(6)](n) MOF can be used as a proof of concept for the incorporation and release of the non-conventional [Ru(p-cymene)Cl(2)(pta)] RAPTA-C metallodrug.

Esterification of (4-hydroxyphenyl)diphenylphosphine, coordinated to the [Ru(η6-p-cymene)Cl2] fragment, allows a series of bioactive carboxylic acids to be introduced directly into the organometallic molecule. Evaluation of the compounds on human ovarian cancer cells reveals synergistic enhancements in their antiproliferative activity relative to their bioactive organic and organometallic precu...
