Quinic add

In other A. deliciosa, A. chinensis, and A. rufa fruits, the compositions of organic adds are fundamentally equivalent to those in Hayward. In A. arguta fruit, the concentrations of quinic add are 0.60. 71 g/100 g FW somewhat lower than that in Hayward (Nishiyama et al, in preparation). 

The predominant organic adds in commonly consumed fruit are citric and/or malic acids. Actinidia fruits are unusual in that quinic acid levels are similar to that of citric add as the predominant organic add. Although the nutritional importance of quinic add has not been established, it is an intensely interesting compound because it is a key intermediate for aromatic compound biosynthesis via the shikimic add pathway. Moreover, quinic add is a component of several potent free radical scavengers, including chlorogenic add. 

Hydroquinone (p-dihydroxybenzene) was first produced by Pierre Joseph Pelletier and Jean Caventou in 1820, by dry distillation of quinic add. The structure was elucidated by Friedrich Wohler in 1844.

Structural formulae have been given for most of the compounds discussed in the text and the major change in nomenclature which has been utilised concerns the numbering of the ring systems of both (—)-shikimic acid and (—)-quinic add. Revised systems of numeration have been employed for these compounds to accord respectively with normal lUPAC procedures and with the tentative rules for cyclitol nomenclature (lUPAC information bulletin. No. 32, 1968 European J. Biochem., 1968, 5, 1).
