Quantitative analysis of areca catechu (betel) nut flavanols (tannins) in relation to oral submucous fibrosis. 1987

M Noor Awang

The processed areca catechu (betel) nuts are popularly chewed in the Indian sub-continent. The significance of areca flavanol (tannin) in relation to oral submucous fibrosis and oral carcinogenesis has been reviewed. The quantitative analysis of ten different commercial nut samples from Bombay, India showed wide variations and a higher than average content of flavanols. These variations reflect their appeal and also influence the predisposition of these diseases. The incidence of oral submucous fibrosis and the nut flavanol contents from Bombay and Kerala were taken for comparisons.

D013634	Tannins	Polyphenolic compounds with molecular weights of around 500-3000 daltons and containing enough hydroxyl groups (1-2 per 100 MW) for effective cross linking of other compounds (ASTRINGENTS). The two main types are HYDROLYZABLE TANNINS and CONDENSED TANNINS. Historically, the term has applied to many compounds and plant extracts able to render skin COLLAGEN impervious to degradation. The word tannin derives from the Celtic word for OAK TREE which was used for leather processing.	Tannin
