Recent work [64] by Kiljunen and Kanerva has been directed towards the search for novel sources of (R)-oxynitrilases which may transform bulky aryl aldehydes. For this purpose whole cell preparations (called meal) from apple seeds and cherry, apricot and plum pips were tested for their (R)-cyanohydrin activity. In this study a comparison of almond and apple meal showed that they possess similar properties for the formation of the (R)-stereogenic centre. However, in certain cases higher enantioselectivity was observed using the apple meal preparation. Additionally, apple meal (R)-Hnl has also been applied to transform ketones into their corresponding cyanohydrins [65] thus creating a wider repertoire of substrates for this latest of (R)-Hnls. Thus it has only recently been shown that apple meal (R)-oxynitrilase is now an additional member of the (R)-Hnl family. [Pg.41]

For phenolics in fruit by-products such as apple seed, peel, cortex, and pomace, an HPLC method was also utilized. Apple waste is considered a potential source of specialty chemicals (58,62), and its quantitative polyphenol profile may be useful in apple cultivars for classification and identification. Chlorogenic acid and coumaroylquinic acids and phloridzin are known to be major phenolics in apple juice (53). However, in contrast to apple polyphenolics, HPLC with a 70% aqueous acetone extract of apple seeds showed that phloridzin alone accounts for ca. 75% of the total apple seed polyphenolics (62). Besides phloridzin, 13 other phenolics were identified by gradient HPLC/PDA on LiChrospher 100 RP-18 from apple seed (62). The HPLC technique was also able to provide polyphenol profiles in the peel and cortex of the apple to be used to characterize apple cultivars by multivariate statistical techniques (63). Phenolic compounds in the epidermis zone, parenchyma zone, core zone, and seeds of French cider apple varieties are also determined by HPLC (56). Three successive solvent extractions (hexane, methanol, aqueous acetone), binary HPLC gradient using (a) aqueous acetic acid, 2.5%, v/v, and (b) acetonitrile fol-... [Pg.792]

Nitsch (15) and Harada and Nitsch (4) have reported R/ values for gib-berellin-like substances in solvent system 2. The R.M. values of 122 and 175 from immature apple seed (15) correspond to A5 and A9, respectively substance E (R.M. = 130-195) from photo-induced Rudbeckia (4) corresponds to A9. [Pg.24]

The Romans used cyanide from natural seed sources, such as apple seeds, for executions and suicides. The seeds of apples, apricots, cherries, peaches, plums, and some other fruits contain sources of cyanide. Other natural sources of cyanide include arrowgrass, sorghum, flax, velvet grass, and white clover. [Pg.252]

The CBD (or Central Business District) is the catchy name for New Orleans downtown. Quick lunches are the focus of downtown eateries, and the Apple Seed Shoppe (336 Camp St., b 504-529-3442) is no exception. The Apple Seed is best known for its quick service and killer salads. Call ahead for take-out. [Pg.109]

You may have heard about plants with the potential for cyanide toxicity— young sorghum-sudangrass and apple seeds and wild cherry. You may have also heard that very low levels of cyanide are usually not dangerous because animals can detoxify these molecules. [Pg.336]
