Three natural aromadendrane sesquiterpenes, (-)-epiglobulol, (-)-4β,7α-aromadendranediol, and (-)-4α,7α-aromadendranediol, have been synthesized in only seven steps in 12, 15, and 17 % overall yields, respectively, from (E,E)-farnesol by a stereodivergent gold(I)-catalyzed cascade reaction which forms the tricyclic aromadendrane core in a single step. These are the shortest total syntheses of t...

Free and glycosidically-bound aromatic characterization of 21 minority red grapevine varieties was carried out, along three consecutive vintages, using solid phase microextraction followed by gas chromatography-mass spectrometry methodology (SPME-GC-MS). The two main study aims were to evaluate the possibility aromatically differentiated based on their origin test profile for being used as a ch...

Copaiba oil (CO) is an oleoresin containing resinous acids, comprising mainly of diterpenes, and volatile compounds, sesquiterpenes. CO has been used for many years as a therapeutic agent cosmetic, being the β-caryophyllene (CAR) one main sesquiterpene markers found in samples. During last years, some analytical methods have developed analysis sesquiterpenes like CAR from CO. However, these are...

The incidence of arthritis is increasing every year, as does the need for pain medication. The current work reviews an American Indian liniment that is traditionally used for pain therapy. The chemistry, therapeutic use and safety of the liniment are reviewed. The liniment contains monoterpenoids, sesquiterpenes, flavonoids, alkaloids and other compounds.

The metabolites of two different Ripartites species, R. tricholoma (A. & S. ex Fr.) Karst. and R. metrodii Huijsm. were investigated. Three new sesquiterpenes were isolated from three different strains. In addition, the strains produced 13-oxo-9(Z),11(E)-octadecadienoic acid, psathyrellon A, 5-desoxyilludosin, an illudane (previously isolated from a Bovista sp.) 96042 and demethylovalicin, five...

During wine aging, tobacco and balsamic aroma notes appear. In this paper, volatile compounds directly or potentially related to those aromas have been investigated in Corvina and Corvinone wines during aging. Corvina and Corvinone are two northern-Italy autochthonous red grape varieties, used to produce Valpolicella Classico and Amarone wines, both characterized by tobacco and balsamic aroma n...
