From the methanolic extract of the rhizomes of Curcuma comosa cultivated in Thailand, six new sesquiterpenes, (+)- and (-)-comosols (1, 2), comosones I (3), II (4), and III (5), and dimethoxycurcumenone (6), were isolated. Their structures were elucidated on the basis of chemical and physicochemical evidence.

We aimed to compare the anti-inflammatory activities of six species of Curcuma drugs using adjuvant arthritis model mice. When orally administered 1 day before the injection of adjuvant, the methanol extract of Curcuma phaeocaulis significantly inhibited paw swelling and the serum haptoglobin concentration in adjuvant arthritis mice. Also when orally administered 1 day after the injection of ad...

Curcuma, a genus of rhizomatous herbaceous species, has been used as a spice, traditional medicine, and natural dye. In this study, the metabolite profile of Curcuma extracts was determined using gas chromatography-time of flight mass spectrometry (GC/TOF MS) and ultrahigh-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF MS) to characterize differences b...

The drug Vanaharidra is used in various kinds of diseases like Kusta, Kasa, etc., Pharmacognosy of the root and rhizome of Vanaharidra is presented in this paper.

In recent year there has been rapid increase in the standardization of selected medicinal plant of potential therapeutic significance. Despite the morden techniques, identification of plant drug by Pharmacognostic study is more reliable. The rhizomes of Curcuma longa reported to have good medicinal values in traditional system of medicines. The present study deals with pharmacognostic parameter...

Neocurdione, isoprocurcumenol, and a new sesquiterpene, 9-oxo-neoprocurcumenol, were isolated from fresh rhizomes of Curcuma aromatica and Curcuma zedoaria (Zingiberaceae) as attachment inhibitors against the blue mussel, Mytilus edulis galloprovincialis. The structures of these compounds were elucidated on the basis of spectroscopic evidence.
