Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.

The aim of the study was to investigate the sesquiterpene constituents from the rhizomes of Curcuma wenyujin Y. H. Chen et C. Ling. The isolation and purification of the constituents from the 50% EtOH extracts of the rhizomes were performed with repeated column chromatography over sillica gel and macroporous resin. Eight sesquiterpenes were obtained and identified as wenyujinlactone A (1), neolitamone A (2), zedoarondiol (3), isozedoarondiol (4), aerugidiol (5), curcumol (6), curdione (7) and (1R, 10R)-epoxy-(-)-1, 10-dihydrocurdine (8) by means of spectral analysis. Among them, compound 1 was found to be a new eudesmane sesquiterpene lactone, whilst compounds 2-5 were obtained from this plant for the first time.

The dynamic accumulation rule of active substances in medicinal plants is of great value not only for medicinal material production and application,but also for the genetic mechanism study on the formation of medicinal ingredients,especially vital to guide medicinal material collection as well as experiment material selection and candidate gene screening in the analysis of biosynthesis pathway. This study investigated the accumulation of curcumins and terpenoids,and the biosynthesis of these metabolites,which are the active metabolites in Curcuma longa,a commonly used traditional Chinese medicine. Rhizoma of C. longa from leaf growing period,rhizome swelling period and dry matter accumulating period were used as experimental materials,to analyze the changes of metabolites and biosynthesis in the three periods by comparative transcriptome and metabolomes analysis.The results indicated that terpenoids accumulation and biosynthesis mainly occurred in leaf growing period,while curcumin accumulation and biosynthesis mainly occurred in dry matter accumulating period. Therefore,we suggested that turmeric rhizomes in leaf growth period were suitable for terpenoids biosynthetic pathway characterization,and rhizome in accumulation of dry matter period was suitable for curcuminoid biosynthesis pathway characterization. This study provides references for medicinal materialproduction and application,as well as biopathway analysis of active compounds for C. longa.
