[Herb honey containing sulforaphane-aglycone with potential use in cancer prophylaxis]

Cruciferous vegetables play an important role because of their sulphorafane contents which are enzymatically released from the glucosinolate known as glucoraphanin. The physiological properties of the compound exhibit antitumorigenic activity. The work describes the chloroform extraction method of sulforaphane from the broccoli and the preparation of sulforaphane sugar extract. The extract was then used to feed bees in a specially constructed beehive so that sulforaphane could be transformed into herbal honey. The concentration of sulforaphane was determined in the obtained herbal honey as high as 1.2 microM.
