CURRENT SCIENCE, VOL. 81, NO. 3, 10 AUGUST 2001 248 by repeating the experiment at least once. A total of 34 decamer primers (series OPA, OPB etc.) from Operon Tech, CA, USA were screened using three representative genomic DNA samples of black pepper. Of these, 24 primers that yielded consistent and clear band patterns were selected for the final analysis of the 22 accessions used in the presen...

The efficiency of applications through spraying is connected to the capacity minimize losses by endo-drift and exo-drift while ensuring adequate coverage deposition on target surface; spray nozzles main factor application quality. However, few researches focus technology in black pepper crops. objective this work was evaluate droplets simulated herbicide using different nozzles. experiment cond...

Developing effective ways for controlling the quality of natural products that are sold in high volume worldwide is currently one most urgent goals analytical chemistry. Black pepper ( Piper nigrum ) a major spice constitutes 34% global market. highly prone to variations, arising from alteration piperine content. Miniaturized NIR spectroscopy offers high-throughput, cost-effective and laborator...

Piperine is a type of bioactive compound that can be isolated from black pepper. Currently the utilization piperine dominated by health sector. In this study, was using Soxhlet method. The purpose research to propose mathematical model determine value diffusivity (DA) piperine, extraction rate constant (k) and isolation equilibrium for commercial designs. Based on results obtained DA at 0.1878 ...
