Liver, heart, kidneys, muscle and adipose (perirenal and subcutaneous) tissues were collected from six animals for analysis of their hydrocarbon composition. Qualitative and quantitative determinations were carried out by gas chromatography and combined gas chromatography-mass spectrometry. Although differing in the proportions, a homologous series of n-alkanes ranging from n-C12 to n-C31 was found in all the samples examined. The isoprenoid hydrocarbons phytane and phytene (phy-1-ene and phyt-2-ene) were also identified.

Different cultivars of kiwifruit (Actinidia deliciosa) (A. Chev.) C.F. Liang et A.R. Ferguson) were harvested in 4 consecutive years and analysed at harvest time. The cultivars were: 'Abbott', 'Bruno', 'Elmwood', 'Fatma', 'Gracie', 'Hayward', 'Monty', and two 'Hayward' clones--'Priori' and 'Tenna'. Major differences, not only· between cultivars but also within cultivars, were observed for vitamin C content 'Bruno' fruit had the highest and 'Abbott' the lowest mean vitamin C content The main nutrients (water, sugar, acid, pectin, dietary fibre), individual sugar, and organic acid composition and indicative sugar: acid ratios are reported. In terms of sensory characteristics, 'Bruno' and 'Fatma' fruit were favoured over the other cultivars. The relatively high dietary fibre content of the fruit is mostly insoluble. With regard to the organic acids, there was a prevalence of citric acid.
