Development of a micellar electrokinetic capillary chromatography method for the determination of four naphthalenediols in cosmetics and a comparison with a HPLC method

Electrophoresis (2020)

Xiaobin Li Zhihan Zheng Huitao Liu Yuan Gao

Abstract A micellar electrokinetic capillary chromatography (MEKC) method with ultraviolet visible (UV) detection was used for the determination of 1,7‐naphthalenediol, 2,3‐naphthalenediol, 1,5‐naphthalenediol, and 2,7‐naphthalenediol in cosmetics. The current method for their determination in various cosmetics is high‐performance liquid chromatography (HPLC). Separation conditions affecting the MEKC method were optimized as 20 mM Na 2 B 4 O 7 –50mM SDS, pH 9.8, with 22 kV applied voltage and UV detection at 230 nm. Under optimal conditions, electrophoretic analysis was completed in less than 6 min, with limit of detection (LOD) of 0.070–0.19 μg/mL and limit of quantitation (LOQ) of 0.23–0.63 μg/mL. A good linear relationship ( r 2 > 0.99) was obtained at the range of 0.75–20 μg/mL. Recoveries for the four naphthalenediols in lotion, loose powder, and sun cream are between 91.2–107.2% with relative standard deviation (RSD) less than 4.04%. The method has been successfully applied to the determination of the four naphthalenediols in different kinds of cosmetics. A comparison with HPLC‐UV method was also carried out according to the National Standards of the People's Republic of China. The results obtained by MEKC and HPLC methods are comparable, but the proposed MEKC method can help us obtain a much shorter detection time and low cost.

Determination of vanadium in water samples by reaction cell inductively coupled plasma quadrupole mass spectrometry

Journal of Analytical Atomic Spectrometry (2002)

Huitao Liu Shiuh‐Jen Jiang

An inductively coupled plasma quadrupole mass spectrometer (ICP-QMS) equipped with a dynamic reaction cell (DRC) was used for the determination of vanadium and its species in water samples. The effect of the operating conditions of the DRC system was studied in order to obtain the best signal to noise ratios. The potentially interfering 35Cl16O+ and 34S16OH+ at the vanadium m/z value of 51 were reduced in intensity by approximately four orders of magnitude by using NH3 as the reaction cell gas in the DRC. The detection limit for 51V was 0.006 ng ml−1. In addition, reversed-phase ion-pair liquid chromatography (LC) was coupled with ICP-MS for the determination of various vanadium species. The limits of detection for VIV and VV were 0.007 and 0.013 ng ml−1 V at m/z 51, respectively, based on peak height. This method was applied to the determination of vanadium in NRCC SLRS-3 Riverine Water reference sample, NRCC SLEW-2 Estuarine Water reference sample and water samples collected locally. The result for the reference sample SLRS-3 agreed satisfactorily with the reference value. The results for which no reference values were available were also found to have satisfactory recoveries. The recovery was in the range of 87–109% and the precision between sample replicates was better than 14% for all the determinations.

High-yield Seed Production Techniques for Quality Hybrid Rice C-liangyou343

Hunan Agricultural Sciences (2012)

Huitao Liu

Based on four years breeding practice and large area seed production,the characters of C-liangyou343's parents and its high-yield seed production techniques were summarized.The key of seed production is selecting right sowing period and season,so it should grasp sowing gap rightly.The optimum sowing gap between parents for C liangyou343 in Southern Hunan area was as follows: female parent should sowing 8-13 days later than male parent when leaf age gap was 2.0～2.5 leaves.Meanwhile,in order to ensure the high-yield,it should breed multi-tiller seedlings to lay a good foundation for high-yield;to transplant seedlings at right time and with proper planting density;strengthening management of fertilizer and water to create high-yield colony structure;spraying 920 to improve out-crossing rate scientifically;removing impurity rigorously to ensure the quality of seeds;strengthening control of diseases and insect pest.

Dispersive liquid‐liquid microextraction for four phenolic environmental estrogens in water samples followed by determination using capillary electrophoresis

Electrophoresis (2016)

Junying Liu Wenhui Lü Huitao Liu Xiaqing Wu Jinhua Li

Dispersive liquid‐liquid microextraction (DLLME) coupled with CE was successfully developed for simultaneous determination of four types of phenolic environmental estrogens (PEEs), namely hexestrol (HS), bisphenol A (BPA), diethylstilbestrol (DES) and dienestrol (DS). Several parameters affecting DLLME and CE conditions were systematically investigated including the type and volume of extraction solvent and dispersive solvent, extraction time, salt, pH value, surfactant, buffer solution and so on. Under the optimal conditions, DLLME‐CE exhibited strong enrichment ability, presenting high enrichment factors of 467, 241, 367 and 362 for HS, BPA, DES and DS, respectively, as well as low detection limits of 0.3, 0.6, 0.6 and 0.3 μg/L, respectively. Excellent linearity was achieved in the range of 2.0–150 μg/L for HS and DS, and 4.0–300 μg/L for BPA and DES, with correlation coefficients R >0.9983. Recoveries ranging from 70.4 to 108.1% were obtained with tap water, lake water and seawater samples spiked at three concentration levels and the relative standard deviations (RSDs, for n = 5) were 2.1–9.7%. This DLLME‐CE method with high selectivity and sensitivity, high stability, simplicity, cost‐effectiveness, eco‐friendliness was proved potentially applicable for the rapid and simultaneous determination of PEEs in complicated water samples.

Comparative Biomass Production of Six Oat Varieties in a Saline Soil Ecology

Communications in Soil Science and Plant Analysis (2014)

Lipu Han A. Egrinya Eneji Yosef Steinberger Wenhui Wang Shuhui Yu

AbstractOat is widely used as a food source in human and animal diets. In China, supplementary cultivation of oat has recently been extended into marginal saline soils, due to its extensive use. The goal of the present study was to explore and compare the agronomic characteristics, biomass production, and distribution of oat in coastal saline soil. A single-factor randomized block design experiment with six naked and husked oat varieties [Bayou-1 (BU-1), Baiyan-2 (BY-2), Baiyan-7 (BY-7), Huawan-6 (HW-6), Huazao-2 (HZ-2), and Pin-16 (P-16)] as treatments was conducted in the Hebei Province of China. The growth period (77 to 88 days) of the six oat varieties were shorter in saline soil than their original breeding region. Moreover, the plant was shorter, with a lower grain number per plant and seed setting. Grain weight increased and no change was observed in the floret number in coastal saline soil relative to the original habitats. The BY-7 variety produced the highest biomass value of 7.0 t ha−1 compared to the other five varieties. Compared with two active growth points, most varieties in the present study showed just one growth activity point between elongation and heading. Two fast growth periods for the six oat varieties were due to the high total leaf biomass growth rate (BGR) from elongation to heading and panicle BGR from heading to maturity. The biomass growth ratio (BGO) during elongation to heading was the largest among the four growth stages of the oat varieties. The number of kernels per spike decreased at the research site, but grain weight increased. Substantial differences were observed for growth periods, biomass, BGR, BGO, and other agronomic characters in the coastal saline soil of North China, but the BY-7 variety was the most suitable variety for the study site.Keywords: Agronomic charactersbiomassgrowth rategrowth ratiooat AcknowledgmentsThe authors thank Professor Chang Z.
