“…[17][18][19][20] Yet, current trends have been directed to expand the scope of this technique to the monitoring of bioprocesses (e.g. fermentations), [21,22] the assessment of the quality of foodstuffs [23][24][25] and cosmetics [26,27] and the probing of target species in environmentally relevant matrices. [16,[28][29][30][31][32][33][34][35][36][37][38] Such measurements are based on the deployment of a semi-permeable hydrophilic membrane into the target medium.…”

Environmental context. There is a need for slightly invasive techniques capable of in-situ probing of target analytes in environmental compartments. Owing to its passive sampling mode and small probe dimensions, microdialysis-based dosimetry is an appealing tool for monitoring of solute concentrations in both water bodies and pore soil waters with minimum disturbance of natural equilibrium. The development of field applications is challenging but will provide novel insights as to the speciation and bioaccessibility of environmental pollutants, e.g. trace metals, at high spatial resolution.Abstract. In-situ sampling of soil pore water is still a challenge for environmental scientists. Here, microdialysis is explored for probing metal concentrations in soil pore water at soil moisture contents ranging from 50 to 115% of the maximal water holding capacity and is compared with traditional sampling by suction cups. Metal concentrations obtained by the suction cup technique were consistently larger than those measured in the dialysate. Good agreement was obtained for Pb and Cu at soil moistures close to saturation after accounting for diffusion resistances whereas corrected Ni and Cd concentrations in the dialysates exceeded those measured by the suction cup technique. These deviations reflect inherent differences in the sampling mode and effects of soil heterogeneity at the microscale. Microdialysis offers new opportunities to probe solute concentrations at high spatial resolution and minimal disturbance of soil conditions at environmental interfaces such as the plant rhizosphere or at the transition between forest floors and the mineral soil.

“…Arbutin may release hydroquinone following in vivo cleavage of the glycosidic bonds or via hydrolysis by human skin bacteria [13]. Several analytical methods have been reported for the quantitative determination of arbutin in cosmetics using high-performance liquid chromatography (HPLC) [6,[14][15][16][17][18], microdialysis sampling coupled to HPLC [19] and HPLC with chemiluminescence detection [20], gas chromatography/mass spectrometry [21], micellar electrokinetic capillary chromatography (MEKC) [22], MEKC with amperometric detection [23], and online derivatization followed by disposable electrochemical sensing [24]. Moreover, hydroquinone has been analysed in cosmetic creams and topical dermatologic drugs using HPLC [16,[25][26][27], capillary electrochromatography [28], MEKC [22,29], spectrophotometry [30], thin layer chromatography [31] and biomimetic sensor technology [32].…”

“…Both arbutins were found to be less stable in liquid preparations, with a major loss in the presence of basic solutions, such as sample C5. b-Arbutin is reported to be a highly photosensitive compound [20], and sunscreen agents are often added in whitening cosmetics to prevent barbutin degradation. After UV exposure, the pH conditions may affect the stability of the compounds, and accelerate the decomposition rate.…”

Both arbutins were found to possess similar stability profiles, and to be more prone to in vivo rather than in chemico degradation, although no HQ was found after enzymatic hydrolysis. Also, no epimerization was observed in any of the tested conditions. Diverse experimental approaches can be applied to analyse the chemical and enzymatic stability of arbutins in regard to the potential release of HQ in different types of preparations. These result showed the potential use of NMR and OR as complementary investigative tools for the stability and safety assessment of arbutin along with more established HPLC methods.
