Curcumaromins A, B, and C, Three Novel Curcuminoids from Curcuma aromatica

Helvetica Chimica Acta (2015)

Xiang‐Dong Qin Yan Zhao Yuan Gao Fu‐Cai Ren Shu Yang

Abstract Three novel curcuminoids, curcumaromins A–C ( 1 – 3 , resp.), along with a known compound, longiferone B ( 4 ) were isolated from Curcuma aromatica Salisb . The structures of the new compounds were elucidated as (1 E ,4 Z ,6 E )‐5‐hydroxy‐7‐{4‐hydroxy‐3‐[(1 R* ,6 R* )‐3‐methyl‐6‐(propan‐2‐yl)cyclohex‐2‐en‐1‐yl)phenyl}‐1‐(4‐hydroxyphenyl)hepta‐1,4,6‐trien‐3‐one ( 1 ), 2,3‐dihydro‐2‐(4‐hydroxyphenyl)‐6‐[( E )‐2‐(4‐hydroxyphenyl)ethenyl]‐5‐[(1 R* ,6 R* )‐3‐methyl‐6‐(propan‐2‐yl)cyclohex‐2‐en‐1‐yl]‐4 H ‐pyran‐4‐one ( 2 ), and (1 E ,6 E )‐1,7‐bis(4‐hydroxyphenyl)‐4‐[(1 R* ,6 R* )‐3‐methyl‐6‐(propan‐2‐yl)cyclohex‐2‐en‐1‐yl]hepta‐1,6‐diene‐3,5‐dione ( 3 ) on the basis of spectroscopic analysis. Curcumaromins A–C ( 1 – 3 ) represented the first examples of menthane monoterpene‐coupled curcuminoids. The known compound, longiferone B ( 4 ), was the first daucane sesquiterpene isolated from the genus Curcuma.

A New Sweet Dihydrochalcone-Glucoside from Leaves of Lithocarpus pachyphyllus (Kurz) Rehd. (Fagaceae)

Zeitschrift für Naturforschung C (2003)

Xiang‐Dong Qin Ji‐Kai Liu

Abstract A new sweet dihydrochalcone-glucoside, trilobatin 2″- acetate (1), was isolated from the leaves of Lithocarpus pachyphyllus, together with phlorizin and trilobatin. The structures were established by spectroscopic methods, including one- and two-dimensional NMR (COSY, HMQC and HMBC).

Optimization of Enzyme-Assisted Extraction of Carotenoids Antioxidants from Cordyceps militaris Using Response Surface Methodology

International Journal of Food Engineering (2017)

Baijuan Wang Qingsong Yang Ting Chen Xiang‐Dong Qin Junrong Ma

Abstract Response surface methodology (RSM) with a Box–Behnken design (BBD) was used to optimize the extraction conditions of carotenoid antioxidants from Cordyceps militaris . An enzyme-assisted extraction (EAE) method was developed and optimized to enhance 2,2-diphenyl-1-picrylhydrazil (DPPH) radical-scavenging activity of carotenoid antioxidants from C. militaris . The optimum conditions were as follows: a pH of 4.1, an extraction time of 40.4 min, an extraction temperature of 48.7 °C and 0.43 % enzyme (cellulose: pectinase, 1:1, w/w) concentration. Under these conditions, the DDPH radical-scavenging activity of C. militaris extracts was 81.62±2.26 %, indicating that the BBD is an efficient approach to develop mathematical models for predictingcarotenoids antioxidant extraction from C. militaris . The successful extraction of carotenoid antioxidants from C. militaris provides a basis for the development and utilization of C. militaris resources.
