Determination of capsaicin, dihydrocapsaicin, and.
Chili peppers are the major source of nature capsaicinoids, which consist of capsaicin, dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, and homocapsaicin, etc. Capsaicinoids are found to exert multiple pharmacological and physiological effects including the activities of analgesia, anticancer, anti-inflammation, antioxidant and anti-obesity.
Genetic analysis revealed that pun12 co-segregated exactly with the absence of blisters, non-pungency, and a reduced transcript accumulation of several genes involved in capsaicinoid biosynthesis. Collectively, these results establish that blister formation requires the Pun1 allele and that pun12 is a recessive allele from C. chinense that results in non-pungency.

The capsaicinoid concentration of varies depending on the type of pepper that is used in the extraction. Mild Capsicum spp contain as little as 0.1-0.2% capsaicinoid, while hot peppers, such as the Jalapeno or the Habanero, contain as much as 0.6-1.4% capsaicinoids. It also depends on what parts of the pepper are used in the extraction.
Capsaicinoid is phenolic pungent compounds that have been found mostly in Capsicum fruits and contribute to 90% of pungency of pepper fruits. The objective of this study is to investigate the phytochemical contents of Capsicum between Capsicum frutescens (Chili padi) and Capsicum annum (Chili pepper and Bell pepper). 2. 2.

The phylogenetic analysis and comparison of critical amino-acid residues for enzyme function showed that the two COMTs had high similarity with the COMTs of other plant species. Moreover, as the two Comts were both expressed in placenta tissue and expressed prior to the accumulation of capsaicinoids, the two genes could be candidates for capsaicinoid biosynthesis.
