En enzyme system has been found in peas which converts mevalonic acid to isoprenoid compounds. Among the intermediates in such conversion are mevalonic acid-5-phosphate and pyrophosphate, isopentenyl pyrophosphate and dimethylallylpyrophosphate. Among the products formed by the system are the pyrophosphates of geraniol, farnesol, nerolidol and higher isoprenoid alcohols.

The essential oil of Helichrysum italicum significantly reduces the multidrug resistance of Enterobacter aerogenes, Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii. Combinations of the two most active fractions of the essential oil with each other or with phenylalanine arginine beta-naphthylamide yield synergistic activity. Geraniol, a component of one fraction, significan...

We have modified the flavor and aroma of tomatoes by expressing the Ocimum basilicum geraniol synthase gene under the control of the tomato ripening–specific polygalacturonase promoter. A majority of untrained taste panelists preferred the transgenic fruits over controls. Monoterpene accumulation was at the expense of reduced lycopene accumulation. Similar approaches may be applicable for carot...

flower of rosa damascena mill is widely used in iran for gastrointestinal (gi) disorders. however, its pharmacological action on ileum contraction has not been studied. in this research we have investigated ileum motility effect of essential oil of flower petals of r. damascena growing in kashan, iran, and two of its constituents. the essential oils obtained by hydrodistillation were investigat...

Hop-derived volatile organic compounds (VOCs) and their transformation products significantly impact beer flavour aroma. Geraniol, a key monoterpene alcohol in hops, has been reported to undergo yeast-modulated biotransformation into various terpenoids during fermentation, which impacts the citrus floral aromas of finished beer. This study monitored evolution geraniol its throughout fermentatio...
