curcumenol/curcuma phaeocaulis

OBJECTIVE To investigate the chemical constituents of the rhizome of Curcuma phaeocaulis Val. METHODS The constituents were isolated by column chromatography and their structures elucidated by chemical properties and spectroscopic analysis. RESULTS Five compunds have been isolated and identified as

OBJECTIVE To study and establish the fingerprint of Curcuma phaeocaulis by high performance liquid chromatography-mass spectrometry. METHODS LC-MS analysis was carried out in a Hewlett Packard model 1100 liquid chromatograph coupled with electrospray mass spectrometry. The analysis was performed on

The potential use of partial least square regression (PLS-R) models for the prediction of biological activities of a herbal drug based on its liquid chromatography (LC) profile was verified using various extracts of Curcuma phaeocaulis and their cyclooxygenase-2 (COX-2) inhibitory activities as the

The rhizomes of Curcuma phaeocaulis, Curcuma kwangsiensis, Curcuma wenyujin and Curcuma longa are used as Ezhu or Jianghuang in traditional Chinese medicine for a long time. Due to their similar morphological characters, it is difficult to distinguish their origins of raw materials used in clinic.

In this paper, GC-MS and pressurized liquid extraction (PLE) was developed for identification and quantitative determination/estimation 11 sesquiterpenes including germacrene D, curzerene, gamma-elemene, furanodienone, curcumol, isocurcumenol, furanodiene, germacrone, curdione, curcumenol and

Previously, Chinese gajutsu available in Japan was identified, from the chloroplast trnK gene sequence, to be the rhizomes of Curcuma phaeocaulis and two genotypes of C. kwangsiensis. Although we defined the two genotypes, the pl and gl types, on the basis of the nucleotide difference, their
