Abstract

Fragrant edible sesame oil is popular for its unique aroma. The aroma of sesame oil is determined by its volatile organic compound (VOC) profile. Sesame oils produced by different techniques could have different VOC profiles. In addition, blending fragrant sesame oil with refined oil could also alter the VOC profile of the final product. Current practices in aroma analysis, such as sensory evaluation and gas chromatography (GC), still face many restraints. Hence, there is a need for alternatives. We present a novel 14-unit multiplexed paper-based colorimetric sensor for fragrant sesame oil VOC analysis. The sensor was designed to visualize the VOC profile as a color "fingerprint". The sensor was validated with 55 branded sesame oil samples produced by two different techniques, i.e., hot pressing and small milling; the experimental results suggested a processing dependency in color VOC fingerprints. The sensor also demonstrated the potential to detect the change in sesame oil VOC profile due to blending with refined oil, with an estimated limit of detection down to 20% v/v of the refined oil. The colorimetric sensor might be used as a simple, rapid, and cost-effective analytical tool in the production and quality control of fragrant sesame oil. [ABSTRACT FROM AUTHOR]

Abstract

Three new diterpenoids, yuexiandajisu D (1), E (2) and F were isolated from the roots of Euphorbia ebracteolata, along with eight known diterpenoids, jolkinolide B (4), jolkinolide A, ent-11 alpha-hydroxyabieta-8(14),13(15)-dien-16,12 alpha-olide (6), ent-(13S)hydroxyatis-16-ene-3,14-dione, ent-3 beta,(13S)-diliydroxyatis-16-en-14-one, ent-3-oxokaurane-16 alpha,17-diol, ent-16 alpha,17-dihydroxyatisan-3-one and ent-atisane-3 beta,16 alpha,17-triol. The structures of all compounds were deduced using spectroscopic methods and confirmed for 1 and 2 by single-crystal X-ray diffraction. A biogenetic pathway for the formation of 1 and 2 is proposed briefly. Cytotoxic activities were evaluated against ANA-1, B 16 and Jurkat tumor cells. Jolkinolide B (4) displayed modest activity on ANA-1, B 16 and Jurkat tumor cells with IC50 values 4.46 x 10(-2), 4.48 x 10(-2), 6.47 x 10(-2) mu M, and ent-11 alpha-hydroxyabieta-8(14), 13(15)-dien-16,12 alpha-olide (6) showed significant activity against ANA-1 and Jurkat cells with IC50 values 7.12 x 10(-3) and 1.79 x 10(-2) mu M. Compound 1 was found to be slightly active against ANA-1 cells with an IC50 value 2.88 x 10(-1) mu M. Structure-activity relationships of isolated compounds are also discussed.
