Germacrone is one of the major bioactive components in the Curcuma zedoaria oil product, which is extracted from Curcuma zedoaria Roscoe, known as zedoary. The present study designed some novel germacrone derivatives based on combination principles, synthesized these compounds, and investigated
Misclassification of Curcuma species (family Zingiberaceae) may lead to unwanted human exposure to Curcuma elata sesquiterpenes zederone and germacrone which have caused hepatotoxicity and changes in CYP expression in laboratory animals. We investigated how these compounds interact with the human
Germacrone (1) and (4S,5S)-germacrone-4,5-epoxide (2) were isolated, along with guaiane and secoguaiane-type sesquiterpenes, from Curcuma aromatica plants. Compound 2 was derived from 1 and cyclized through transannular (T-A) reactions into various guaiane and secoguaiane-type sesquiterpenes in C.
This study aims to develop a method for determination of beta-elemene, curcumol, germacrone and neocurdione in the volatile oil of Curcuma phaeocaulis, and to provide the basis of the quality control method for the volatile oil of C. phaeocaulis and the related preparations. Based on GC-MS, the 4
High-speed counter-current chromatography (HSCCC) was applied to isolate and purify bioactive compounds in the essential oil of the rhizomes of Curcuma wenyujin. Two sesquiterpenes germacrone and curdione were successfully isolated and purified using two-phase solvent system composed of petroleum
Curcumol, germacrone and curdione are the main active ingredients in a common traditional Chinese medicine (TCM) of Rhizoma Curcuma, and commonly used as the TCM quality control markers. In the present work, microwave-assisted extraction (MAE) followed by headspace solid-phase microextraction
Germacrone is one of the major bioactive components of the traditional Chinese Medicinal plant Curcuma aromatica Salisb. and has been shown to possess anti‑tumor properties. In the present study, the anti‑proliferative effect of germacrone on human glioma cells and the molecular mechanism underlying
Minoxidil is approved for topical treatment of androgenic alopecia but hampered by poor cutaneous absorption. Recently, the randomized control trial showed that hair loss treatment of minoxidil was improved by co-application of the anti-androgen, Curcuma aeruginosa Roxb. extract. Here, we aimed to
OBJECTIVE
To establish a HPLC method for determination of 4 components in different varieties of vinegar backed Rhizoma Curcuma.
METHODS
The method was established by using an Elite Hypersil ODS2 column (4.6 mm x 250 mm, 5 microm). The mobile phase comprising acetonitrile (A) and water (B) was used
A validated new, simple and highly sensitive reversed-phase HPLC method is developed for studying the pharmacokinetics of germacrone after intravenous administration of zedoary turmeric oil (ZTO) oil-in-water microemulsion. The method did not require a complex and expensive equipment. A high
The genus Curcuma is part of the Zingiberaceae family, and many Curcuma species have been used as traditional medicine and cosmetics in Thailand. To find new cosmeceutical ingredients, the in vitro anti-inflammatory, anti-oxidant, and cytotoxic activities of four Curcuma species
Two new sesquiterpenoids-13-hydroxycurzerenone (1) and 1-oxocurzerenone (2)-have been isolated from the rhizomes of Curcuma zedoaria, together with 13 known compounds (3-15). The structures of two new compounds were determined through spectroscopic and MS analyses. Among the isolated compounds,
Anti-androgenic drugs are treatments for androgen-related disorders such as benign prostatic hyperplasia, acne, hirsutism, and androgenic alopecia. Germacrone (1), a sesquiterpene isolated from hexane extracts of Curcuma aeruginosa Roxb. rhizome, is an androgen inhibitor of steroid 5-alpha reductase
Zedoary turmeric oil (ZTO), the steam extract of Curcuma zedoaria Rosc was researched for its chemical composition, antibacterial activity, and mechanism for countering two major food-borne pathogenic species, Listeria monocytogenes and Staphylococcus
