Profiling non-polar terpenes of rhizomes for distinguishing some Indian Curcuma species
The objective of the study is to find biomarker compound(s) in some Indian Curcuma species with the aim to identify, through metabolite profiling and chemometric approach. Total 45 terpenes, including 19 monoterpenes and 16 sesquiterpenes could be detected in the hexane extract of five species of Curcuma e.g. C. amada, C. aromatica, C. caesia, C. longa, and C. zedoaria. Based on terpene profile, dendrogram and OPLSDA separated all the five species from each other. Multivariate analysis carried out considering C. longa as one group and the other species as another group revealed that sesquiterpenes and a few monoterpenes pl...

Development of DNA barcode for rapid identification of Epimedium elatum (Morren & Decne) from Northwestern Himalayas in India
Publication date: Available online 15 June 2019Source: Journal of Applied Research on Medicinal and Aromatic PlantsAuthor(s): Sajad A. Lone, Qazi P. Hassan, Suphla GuptaAbstractEpimedium elatum (Morren & Decne) is a rare monotypic high altitude medicinal species, endemic to shady forests in Northwestern Himalayas, India. Its recent chemoprofiling has revealed high concentration of Epimedin B, C & Icariin, thus matching quality standards of Herba Epimedii. DNA barcode was hitherto unreported in E.elatum. Three plastid genes (matK, rbcL & trnH-psbA) and one nuclear region gene (ITS) were partially sequenced to develop unique...

Publication date: Available online 18 January 2019Source: Journal of Applied Research on Medicinal and Aromatic PlantsAuthor(s): Ly Nguyen, Lam T. Duong, Rao S. MentreddyAbstractThis research applies the Rotterdam model to estimate U.S. import demand for source-differentiated spices and herbs and medicinal plants. The price structure indicates that U.S. import demand for both, spices and herbs are inelastic, with demand responding the most to import prices of herbs from North America and the least to import prices of herbs from Asia and Africa. Asian herbs and medicinal plants are dominant and can substitute for the other ...
