“…Dubey et al, (2015) also observed a reducing power activity ranging from 0.92 to 4.10 ASE/ml in twenty five chilli genotypes from Northeast India which is higher than the findings of our study (0.17±0.00 and 0.55±0.00 absorbance in fresh and dry King chilli respectively). The reducing power significantly decreased in all the secondary processed products.…”

“…annuum followed by selection might have developed low pungent Bhut jolokia genotypes. A recent study by Dubey et al (2015) [30] also reports quantification of capsaicin content of 25 Capsicum genotypes from North Eastern states of India by using spectrophotometry in which they have also reported variations in pungency content. However, in our study we have listed and quantified all the components of capsaicinoids (capsaicin, dihydrocapsaicin, nor dihydrocapsaicin and nonivamide).…”

“…frutescens makes North Eastern India one of the important sources of genetic resources of chili peppers. However, only fragmented studies and reports on diversity in capsicum germplasm, which is based on capsaicinoids are currently available [30,31]. Recently, Islam et al (2015) [32] evaluated the levels of variation in capsaicinoid content in 139 diverse accessions using high performance liquid chromatography (HPLC) method.…”

Comparative Analysis of Fruit Metabolites and Pungency Candidate Genes Expression between Bhut Jolokia and Other Capsicum Species

Bhut jolokia, commonly known as Ghost chili, a native Capsicum species found in North East India was recorded as the naturally occurring hottest chili in the world by the Guinness Book of World Records in 2006. Although few studies have reported variation in pungency content of this particular species, no study till date has reported detailed expression analysis of candidate genes involved in capsaicinoids (pungency) biosynthesis pathway and other fruit metabolites. Therefore, the present study was designed to evaluate the diversity of fruit morphology, fruiting habit, capsaicinoids and other metabolite contents in 136 different genotypes mainly collected from North East India. Significant intra and inter-specific variations for fruit morphological traits, fruiting habits and 65 fruit metabolites were observed in the collected Capsicum germplasm belonging to three Capsicum species i.e., Capsicum chinense (Bhut jolokia, 63 accessions), C. frutescens (17 accessions) and C. annuum (56 accessions). The pungency level, measured in Scoville Heat Unit (SHU) and antioxidant activity measured by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay showed maximum levels in C. chinense accessions followed by C. frutescens accessions, while C. annuum accessions showed the lowest value for both the traits. The number of different fruit metabolites detected did not vary significantly among the different species but the metabolite such as benzoic acid hydroxyl esters identified in large percentage in majority of C. annuum genotypes was totally absent in the C. chinense genotypes and sparingly present in few genotypes of C. frutescens. Significant correlations were observed between fruit metabolites capsaicin, dihydrocapsaicin, hexadecanoic acid, cyclopentane, α-tocopherol and antioxidant activity. Furthermore, comparative expression analysis (through qRT-PCR) of candidate genes involved in capsaicinoid biosynthesis pathway revealed many fold higher expression of majority of the genes in C. chinense compared to C. frutescens and C. annuum suggesting that the possible reason for extremely high pungency might be due to the higher level of candidate gene(s) expression although nucleotide variation in pungency related genes may also be involved in imparting variations in level of pungency.

“…Extraction procedure: The extraction of both the fresh and dried chilli was done using cold maceration method as described by Dubey et al [3]. The fruits of both the dried and fresh chilli were taken separately and washed thoroughly using distilled water to removed dust or any other unwanted particles adhering to the surface of chilli.…”

“…Quantification of total capsaicin content: Capsaicin content was determined by spectrophotometric method [3]. 1 mg of crude extract of both dried and fresh chilli was redissolved in 5 mL of 0.4 % NaOH and 3 mL of 3 % phosphomolybdic acid and allowed to stand for 1 h. The solution was filtered and centrifuged at 5000 rpm for 10 to 15 min.…”
