Abstract Background: Polygonum Cuspidatum Sieb. et Zucc. (named Huzhang in China) is a traditional and popular Chinese medicinal herb used in removing jaundice, clearing heat-toxin, improving blood circulation, expelling stasis, dispelling wind and dampness, repelling phlegm, and suppressing cough. It is widely used in drug and functional food fields and distributed throughout the world, including in China, Japan, and North America. Objective: To control the quality of Polygonum Cuspidatum, an effective, reliable, and simple method for simultaneous determination of two stilbenes (polydatin, resveratrol) and four anthraquinones (emodin, physcion, rhein, and anthraglycoside B) was developed and validated for the first time in this study by reversed-phase HPLC (RP-HPLC). Methods: Separation was carried out on Agilent C18 column (250 × 4.6 mm I.D., 5 μm) with acetonitrile and 0.10% aqueous phosphoric acid as mobile phase and gradient elution at a flow rate of 0.8 mL/min. Detection was conducted with mobile wavelength at 30°C. Results: Good validation of the method including linearity, precision, repeatability, and recovery was performed. The contents of the studied analytes are significantly different, and resveratrol and rhein in particular existed in greater fluctuation among the samples. Conclusion: A simple, reliable, and sensitive method has been successfully established and applied to the analysis for simultaneous determination of the target compounds in 11 batches of samples. Highlights: Separation and quantitative analysis of two stilbenes and four anthraquinones from P. cuspidatum were developed by RP-HPLC. This method is convenient, sensitive, and accurate and can provide a reliable basis for further applications of P. cuspidatum in drug or food fields.

Abstract A simple and sensitive HPLC method has been developed for the simultaneous determination of eight permitted food colors and five commonly encountered nonpermitted colors in various food commodities, including sugar-, fat-, and starch-based food matrixes. The method uses a specific food category-based cleanup/treatment procedure before color extraction to avoid the interference of food matrixes, and to obtain the optimal color extraction. Analysis was performed on a reversed-phase C18 -Bondapak column with ammonium acetate and acetonitrile gradient elution as the mobile phase; a programmable max-specific visible detection was used to monitor colors to obtain the higher sensitivity and expanded scope needed for multicolor blends having diverse absorption maxima. All colors showed good linearity, with regression coefficients of 0.99740.9999. The LOD and LOQ values ranged from 0.01 to 0.12 mg/L, and from 0.04 to 0.83 mg/L or mg/kg, respectively. The intraday and interday precision tests produced good RSD values, and the recoveries from different food matrixes ranged from 82 to 104%. The method offers high sensitivity for analysis of a wide variety of food matrixes containing a broad scope of multicolor blends. Two nonpermitted colors, orange II and metanil yellow, were found. Also, a number of samples contained permitted colors at levels two-to seven-fold higher than those prescribed.

In this study, a sensitive, precise, and accurate HPLC-UV method was developed and validated to simultaneously determine the six analytes (luteolin-7-O-β-D-glucuronide, apigenin-7-O-β-D-glucuronide, diosmetin-7-O-β-D-glucuronide, acacetin-7-O-β-D-glucuronide, tilianin, and rosmarinic acid) in Yixin Badiranjibuya Granules, in which five analytes (i.e., luteolin-7-O-β-D-glucuronide, apigenin-7-O-β-D-glucuronide, diosmetin-7-O-β-D-glucuronide, acacetin-7-O-β-D-glucuronide, and rosmarinic acid) were determined for the first time in Yixin Badiranjibuya Granules, the content of tilianin in Yixin Badiranjibuya Granules was reported in other literatures, and the content of tilianin in our work was higher than that of the literature reports. The quality of 11 batch samples from four different manufacturers was evaluated using the proposed determination method. The contents of the six analytes were largely different among samples from various manufacturers. Therefore, this determination method can provide a scientific basis for quality evaluation and control of Yixin Badiranjibuya Granules.

A rapid reversed phase highperformance liquid chromatography (RP-HPLC) method was developed for the simultaneous analysis of L-ascorbic acid and L-ascorbylpalmitate (AP). The chromatography was performed on a SSI model 2300-525 high performance liquid chromatographequipped with anAlltechApollo C18 column at 30 oC.The mobile phase was acetonitrile-water (90:10,v/v) with the flow rate of 1.0 mL/min. UV detection wavelength was 250 nm. This method permits the simultaneous determination of ascorbic acid and AP in the synthesis of AP transesterified with methyl palmitate and ascorbic acid. The detection limit of ascorbic acid and AP was 0.07μg/mL and 0.12μg/mL, respectively. The recovery was 90.59 ± 3.04% for ascorbic acid and 101.3 ± 4.81% for AP. The linearity range for ascorbic acid and AP was in the range of 0.1 - 0.7 mg/mL and 0.4 - 4.0 mg/mL, respectively. Correlation coefficients (R2) were 0.9910 for ascorbic acid and 0.9986 for AP. The proposed method could be used for routine quality control of AP synthesis with methyl palmitate and ascorbic acidby enzymatic transesterification.

Abstract A selective reversed phase high performance liquid chromatography/photodiode array detector (RP-HPLC/PAD) method has been developed for simultaneous determination of the three co-administrated deflazacort, aprepitant and granisetron drugs used with chemotherapy. The three cited drugs have been chromatographed on C18 column using a mobile phase consisting of acetonitrile–0.2% v/v triethylamine (80:20 v/v, pH of 6.6 ± 0.05) with isocratic elution and monitored by photodiode array at 220 nm. International conference on harmonization (ICH) guidelines were followed to validate the developed method. Successful application of the developed method was assessed by the simultaneous determination of the studied drugs in pure forms, dosage forms and plasma samples in the ranges of 0.2–20, 0.4–40 and 0.2–20 μg/mL for deflazacort, aprepitant and granisetron, respectively.
