Identification of the genus Curcuma is poorly understood. 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 played important role to distinguish species particularly C. longa. Ar-Curcumene, beta-sesquiphellandrene, and alpha-zingiberene were detected in only C. longa. Curzerene, isoborneol, germacrene D could not be detected from C. longa and C. amada. C. caesia is characterized by the presence of delta-cadinene. © 2019 Elsevier GmbH

The aroma and taste of different locally available varieties of Piper betle L. leaves vary due to their essential oil and other constituents. In this study, the essential oils were extracted from seven local varieties of P. betle L. leaves (Bangla, Bagerhati, Manikdanga, Meetha, Kalibangla, Chhaanchi and Ghanagete) with the aim to characterize the varieties on the basis of oil constituents and to study their enzyme inhibitory and cytotoxic properties. Forty five identified essential oil constituents were subjected to different multivariate statistical analyses e. g. PCA, PLS-DA (R2 = 0.40694; Q2 = 0.31199), OPLS-DA (R2X = 0.154; R2Y = 0.742; Q2 = 0.664) and sPLS-DA. The first three statistical models distinguished mainly Chhaanchi, Meetha, Manikdanga from the others. sPLS-DA model separated all the varieties. The biplot, VIP score plot and other loading plots obtained from the above mentioned models identified mainly the phenylpropanes and a few terpenes to be responsible for distinguishing the varieties chemically. The essential oils exhibited very good acetylcholinesterase inhibitory properties, suggesting their potential for enhancing memory function. The essential oils also inhibited β-glucuronidase, involved in excretion of xenobiotics and other materials from the body, and showed cytotoxic properties. The study suggested potential applicability of the P. betle L. leaf essential oils in medical and cosmetic sector. © 2018 Elsevier GmbH
