Isovaleric Acid | ScienceGate

Torquatone has been isolated from forms of Eucalyptus flocktoniae and E. spathulata var. grandifora. Baeckeol has been isolated from Calythrix angulata. Torquatone has been synthesized by condensation of 2,4-dimethylphloroglucinol and isovaleric acid with subsequent methylation.

Main Components

The essential oils obtained by hydrodistillation of the aerial parts of Valeriana parviflora (Trevir) BM Vadillo, an endemic species of the Venezuelan Andes, collected from the same location in two different seasons (dry and rainy) of the year, were analyzed by GC/MS. The essential oil obtained during the dry season showed linalool (11.9%), eugenol (8.9%), p-menth-1-en-9-al (8.7%) and α-terpineol (7.7%) as main components, while the oil obtained from the rainy season collection showed o-xylol (16.2%), 3-methyl isovaleric acid (10.6%) and geranial (9.5%) as major compounds. Some of the differences in the composition of these oils might be due to the climatic conditions at the time of harvesting.

Geographical Locations

The proteolytic activity and volatile fatty acid production of 10 isolates of Clostridium botulinum type F from diverse geographical locations were determined. Two of the 10 strains were non-proteolytic, 3 were slightly proteolytic, and 5 were strongly proteolytic. The non-proteolytic cultures and the slightly proteolytic cultures produced acetic and butyric acid. The strongly proteolytic cultures produced mainly acetic, butyric, isobutyric, and isovaleric acid, and small to trace amounts of propionic, isocaproic, and caproic acid. The relative amounts of the various acids produced were markedly influenced by the growth medium. The addition of glucose to the growth medium caused an increase in the relative amount of butyric acid and a decrease in isobutyric and isovaleric acid.
