Chestnut honey

Some phenolic acids such as ellagic acid can be used as floral markers of heather honey (Cherchi et al., 1994 Ferreres et al., 1996a,b), and the hydroxyciimamates (caffeic, p-coumaric, and ferulic acids) as floral markers of chestnut honey (Cherchi et al., 1994). Pinocembrin, pinobanksin, and chrysin are the characteristic flavonoids of propolis, and these flavo-noid compounds have been found in most European honey samples (Tomas-Barberan et al., 2001). However, for lavender and acacia honeys, no specific phenolic compoimds could be used as suitable floral markers (Tomas-Barberan et al., 2001). Other potential phytochemical markers like abscisic acid may become floral markers in heather honey (Cherchi et al., 1994). Abscisic acid was also detected in rapeseed, lime, and acacia honey samples (Tomas-Barberan et al., 2001). Snow and Manley-Harris (2004) studied antimicrobial activity of phenolics. 

Aminoacetophenone was detected to be specific to Italian chestnut honeys (Bonaga and Giumanini, 1986).

Comparison of the levels of radioactive contamination found in the honeys produced from the different species of trees also provides interesting information. Thus fir honey seems to highly concentrate radionuclides. The Cs and Cs concentrations in chestnut honeys are also generally high. Conversely, acacia honey appears as a weak indicator of radioactive pollution. Our results confirm those found by Tonelli and co-workers [8], who report that the mean concentrations of Cs found in Italian chestnut honey and acacia honey in May-June 1986 were 70.2 58.7Bq/kg (22.2 to 180) and 27.3 19.6Bq/kg (5.1 to 65.5), respectively.

Characterization of Pyrrolidinyl Quinoline Alkaloids from Chestnut Honey... 

In 2009, Baretta and coworkers [81] reported the isolation of two pyrrolidinyl quinoline alkaloids from chestnut honey, 81 and 82. The study was a further exploration of chestnut honey which had been previously shown to contain a significant quantity of kyurenic acid, the final product of tryptophan catabolism. The two new alkaloids isolated from chestnut honey were characterized by 2D NMR methods, which included long-range HMBC data for one of the two compounds reported. This...
