The intermediate, discovered by Rilling, between farnesyl pyrophosphate and squalene was synthesized in milligram quantities with yeast subcellular particles from farnesylJ4Cpyrophosphate and from farnesyl-l-3H&4C-pyrophosphate. The 3H : l4C ratio in the new squalene precursor was found to be identical with that in the farnesyl pyrophosphate, whereas the ratio in squalene was close to the expec...

In this study, we performed the chemical characterization of Myrcia splendens (Sw.) DC. (Myrtaceae) essential oil from Amazonian Ecuador and the assessment of its bioactivity in terms of cytotoxic, antibacterial, and antioxidant activity as starting point for possible applicative uses. M. splendens essential oil, obtained by hydro-distillation, was analyzed by Gas Chromatography-Mass Spectromet...

The cultivated strawberry ( Fragaria × ananassa ) is an economically important fruit crop that intensively bred for improved sensory qualities. diversity of flavors and aromas in results mainly from the interactions sugars, acids, volatile organic compounds (VOCs) are derived diverse biochemical pathways influenced by expression many genes. This study integrates multiomic analyses to identify Q...

The genus Moluccella (Lamiaceae) encompasses eight species among which aucheri (Boiss.) Scheen and M. laevis L. are available in Iran. aim of this study is characterizing the essential oil dried aerial parts collected from South was hydrodistilled then analysed by GC-MS. Twenty-one compounds were identified aucheri. most abundant components an aromadendrane sesquiterpene; spathulenol (63.3%) to...

Volatile components, such as terpenoids, are emitted from aerial parts of plants and play a major role in the interaction between plants and their environment. Analysis of the composition and emission pattern of volatiles in the model plant Arabidopsis showed that a range of volatile components are released, primarily from flowers. Most of the volatiles detected were monoterpenes and sesquiterp...

By implementing a common and industrially used method, 30 compounds which are structurally related to geranyl acetone, nerolidol, farnesal, farnesol and farnesyl acetate were obtained. Their antimicrobial activity against Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii bacteria was investigated. Pharmacophor...

The aerial parts of Artemisia iwayomogi afforded, in addition to already known terpenes, eleven new eudesmanolides whereas four new guaianolides were found in A. gmelinii. No sesquiterpene lactones were detected in the aerial parts of A. santolinifolia which afforded two new nerolidol derivatives besides several other already known compounds. From A. caerulescens var. cretacea six eudesmanolide...
