In replicated trials at Las Cruces, N.M., the Scoville heat units (SHUs) of ‘Bhut Jolokia’, a chile pepper from Assam, India, reached one million SHUs. Morphologic characters revealed that ‘Bhut Jolokia’ is a Capsicum chinense Jacq. cultivar. Molecular analysis with randomly amplified polymorphic DNA markers confirmed the species identification and, interestingly, revealed that there may have been genetic introgression from Capsicum frutescens L. into ‘Bhut Jolokia’.

Capsicum chinense, popularly known as Bhut jolokia, was collected from three states of North-East India and was studied for variation in its pungency principal viz. capsaicinoid content and antioxidant activity as well as its inter-action affinity with human inducible nitric oxide synthase (iNOS) active sites. HPLC fingerprinting analysis showed capsaicin and dihydrocapsaicin as the major active compounds present in the capsaicinoid extract of C. chinense. In comparison to dihydrocapsaicin, capsaicin was found in high amount. The pungency range was observed between 3, 47,301 SHU to 8, 45,296 SHU in the collected samples. The capsaicinoid extract exhibited antioxidant activity with 46.24 ± 15.34% scavenging of DPPH free radical at 100 ppm. The dock-ing analysis showed that capsaicin interacted more with the active sites of iNOS compared to dihydrocapsaicin. Present investigation revealed considerable difference in capsaicinoid content among the samples collected from three states of North-East India. The capsaicinoid showed noticeable antioxidant activity with potent binding affinity to the active sites of iNOS in the molecular docking analysis.

Recent times highly demand an efficient and cost-effective alternative for keratin waste degradation. Studies have shown that microbial hydrolysis of keratin waste is a popular biotechnological substitute for the process of ker-atin waste valorization, which is achieved through the microbial keratinases. To sequester keratinolytic microorganisms with potential to influence com-mercial utilization as keratinase manufacturers, the present work evaluates the endophytic bacterial strains isolated from the host plant Capsicum chinense. Spectrophotometric analysis revealed that out of 4 isolated bacte-rial strains from the root and shoot parts of C. chinense, 1 strain showed sig-nificant caseinolytic and keratinolytic activities. The caseinase enzyme was measured spectrophotometrically and found to be 6.3 U/ml and the keratinase production was measured to be 93U/ml. Bacillus subtilis strain was used as a positive control. Molecular identification showed the efficient endophyte Cb4 to be Enterobacter sps, while the lesser efficient isolate Cb1 was identified as Proteus sps. The potential of the bacterial strains to dena-ture keratin substrates was assessed by SEM, FTIR spectra analysis. Bacterial endophytes isolated from the roots and shoots of C. chinense were tested for their economic importance to replace severe chemical approaches for remediating the environment. The results confirmed the amplified efficacy of the host plant, harboring the beneficial bacterial endophytes.

Bhut jolokia, which is a cultivar of Capsicum chinense Jacq. is known to the world for its high capsaicinoids content. While wild C. chinense forms may be found in eastern lowland of South America, bhut jolokia is grown in the northeastern states of India. Evidences show that bhut jolokia has interspecific origin with introgression of genes of C. frutecens into C. chinense a natural hybridisation. The fruit of the plant and its leaves has been used as ethnobotanical medicine in different parts of the world. Phytochemical analysis has shown that the fruit is rich in capsaicinoids, which is the reason for its high pungency. Capsaicin and dihydrocapsaicin are the two major capsaicinoids adding pungency to chilli. Higher the capsaicin higher is the pungency. Recent studies has shown wide medicinal applications of capsaicin such as pain relief, anti-obesity treatment, as an antioxidant, antimicrobial agent and even as anticancer molecule. The government of Nagaland has patent rights and geographical indications for naga chilli, which will certainly help in the economic prospect of the region from its cultivation. Thus, this review is an attempt to highlight the latest research and developments in bhut jolokia, which has a huge economic potential to prosper the northeastern region of India.
