“…Capillary GC and capillary GC-MS analyses were done with a Hewlett-Packard 5890 gas chromatograph and a Varian 3300 gas chromatograph combined by direct coupling to a Finnigan MAT 44 mass spectrometer with a PCDS data system, with a J & W fused silica DB-5 capillary column (30 m x 0.25 mm i.d., film thickness 0.25 mm) as described elsewhere. 19) Purification of soybean lipoxygenase-2 and -3. A mixture of soybean lipoxygenase isozymes-2 and -3 was obtained as described.…”

“…With the detection of lactones 38a/b a hypothetic cleavage of starfruit carotenoids could be suggested that is shown in Fig. 7 (44)(45)(46) and, consequently, it was reasonable to assume that the remaining C, 5 end group should also be detectable in the fruit.…”

This paper summarizes our studies on the formation of C 13 -norisoprenoid aroma substances in starfruit (Averrhoa carambola L.). The finding that the majority of norisoprenoid volatiles in starfruit are derived from glycosidically bound progenitors stimulated more intense studies into the glycosidic fraction of the fruit. In this paper the isolation and structural elucidation of several novel C 13 -and C 15 -norisoprenoid structures in starfruit is reported and the degradative pathways giving rise to the formation of potent starfruit aroma compounds are discussed. In the last part, attention is focused on possible pathways of carotenoid breakdown in starfruit, thus rationalizing the co-occurrence of C 13 -and C 15 -norisoprenoids with volatiles apparently derived from the central portion of the carotenoid chain.

“…Quinces are important also for the canning industry, especially due to their high contents of pectins (Kyzlink 1990;Forni et al 1994). From the sensory point of view, an intensive quince-like smell represents an important qualitative trait (Lutz & Winterhalter 1992); this is due to an increased content of aromatic substances (Escher & Niclass 1991). Quince fruit can also be used for the production of an aromatic distillate (Naf et al 1991).…”

Rop O., Balík J., Řezníček V., Juríková T., Škardová P., Salaš P., Sochor J., Mlček J., Kramářová D. (2011): Chemical characteristics of fruits of some selected quince (Cydonia oblonga Mill.) cultivars. Czech J. Food Sci., 29: 65-73.The basic chemical characteristics of 22 quince (Cydonia oblonga Mill.) genotypes and cultivars were determined: dry matter content, soluble solid content, the contents of organic acids, pectins, and mineral elements (nitrogen, phosphorus, potassium, calcium, and sodium). Quince fruits were harvested in the course of October and thereafter analysed at the stage of consumption ripeness after storage at the temperature of +2°C and a relative air humidity of 85%. The contents of pectins in fruits were high -the cultivar Hruškovitá contained 3.51 ± 0.19 g/100 g FW. The contents of vitamin C were also high, the cultivar Muškatová containing as much as 79.31 ± 2.01 g/100 g FW. The affinity of chemical properties of the individual cultivars was expressed by means of cluster analysis and it was found out that there were no marked differences between pear-shaped (Cydonia oblonga subsp. pyriformis) and apple-shaped (Cydonia oblonga subsp. maliformis) forms of fruit.
