A Fast and Simple HPLC–UV Method for Simultaneous Determination of Emodin and Quinalizarin from Fermentation Broth of Aspergillus. ochraceus lp_0429

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 269)


A rapid, sensitive and reproducible high performance liquid chromatographic (HPLC) method was developed and validated for simultaneous quantification of Emodin and Quinalizarin from Fermentation Broth of Aspergillus. ochraceus lp_0429. Isocratic RP-HPLC system with C18 column (4.6 mm × 250 mm i.d., 5 μ particle size) and a detector UV-VWD was employed. The mobile phase of 0.05 M disodium hydrogen phosphate and acetonitrile (25:75, v/v) containing 0.5 mL/L triethylamine at pH 5.8 was delivered at flow rate of 0.1 mL/min at ambient temperature. The UV detection of emodin and quinalizarin was set at 254 nm. Total run time was 10 min and retention times for Emodin and Quinalizarin were 2.08 and 6.12 min, respectively.
