Prize at the second stage of ripeness, and in Nobel at both. Ripe varieties of Gem, Hass Motril, and Sir Prize were the only ones where sinapic add was found, with Colin V 33 and Sir Prize being the only varieties that had vanillin. Gallic and vanillic adds were exclusively present in ripe Sir Prize avocado, which turned out to be the richest sample in terms of the number of compounds. 

Fig. 2.7 The effects of pH on the ionic state of a theoretical phenolic acid with a pKa value of 4.5 (a) and estimated pKa values for cinnamic and benzoic acids (b). Where CAF equals caffeic acid, PCO equals p-coumaric acid, FER equals ferulic acid, SIN equals sinapic add, POH equals p-hydroxybenzoic acid, SYR equals syringic acid, and VAN equals vanillic add. A pKa value for caffeic acid was not available. Figure (b) based on data from Blum et al. (1999b). CRC Press LLC, data used with permission of Taylor Francis Ltd, http //www.tandf.co.uk/joumals.

Fig. 2.20 The effects of multiple treatments of 7- (a) and 4- (b) equal-molar phenolic acid mixtures on cucumber seedling rhizosphere bacterial populations that can utilize phenolic acids as sole carbon sources, where CFU equals colony-forming units. Seedlings were grown in Cecil A sou. The 7-phenoUc acid mixture was composed of caffeic.p-coumaric, ferulic.p-hydroxybenzoic, sinapic, syringic, and vanUlic acids. The 4-phenohc add mixture was composed ofp-coumaric, fer-ulic,p-hydroxybenzoic, and vaniUic acids. Figure based on data from Blum et al. (2000).

Esters of 3a-Hydro tropane/-4tortropaiie with Phenylpropanoid Acids (T5). This group of metabolites is a small one with hydroxycinnamic acids as acyl components, i.e., caffeic acid, femlic add, sinapic acid. It is also a rather rarely occurring group (six genera, 12 spedes = 7% of all species checked). Such alkaloids could be... 

Sinapic acid, an important hydroxydnnamic acid is the most significant phenolic compound in rapeseed and forms 70.2-85.4% of free phenolic adds in defatted canola meals. Esterified forms of these phenolic acids constitnte abont 99% of total phenolics in rapeseed flour of which the sinapine, the choline ester of sinapic acid, is the main ester. A phenolic glucoside namely glucopyranosyl sinapate is also reported in canola (Amarowicz and Shahidi, 1994). Figure 2.1 shows the structures of sinapic acid, sinapine and glucopyranosyl sinapate.
