NOVEL CAPSAICINOID LIKE SUBSTANCES IN THE FRUITS OF NEW NGN-PUNGENT CULTIVAR 'CH-19 Sweet' OF PEPPER (Capsicum annuum)

摘要

Capsaicin is the main compound of pungency in pepper fruit and has physical activities for the human body Capsaicin homologs are called capsaicinoid It is possible to utilize capsaicinoid as food additive and in medicine, but strong pungency limits the use of capsaicinoid. In 1979, Yazawa introduced a hot pepper 'CH-19 Pungent' from Thailand and produced the original non-pungent pepper by selfing and selection of 'CH-19 Pungent' and named it 'CH-19 Sweet' Yazawa found that 'CH-19 Sweet' fruit is little pungent, but contains capsaicinoid like substances (CLSs, tentatively named CLS-A, CLS-B). Kobata etal (1998) found that CLS-A is a vanillyl alcohol and CLS-B is a capsaicin analog. CLS-B was named capsiate. A putative capsiate biosynthetic pathway is shown in Fig. 1 (Watanabe et al., unpublished).
