“…EY in examined samples decreased with a low X 3 , increased with more X 3 . This is probably because the less solvent is leading to incomplete extraction, whereas too much solvent can result in a high experimental cost [ 32 ].…”

“…Moreover, experimental results of response variables were similarly influenced by X 4 as the change of time in the medium. Jeong et al [ 32 ] and Zheng et al [ 34 ] testified that factors with the most influence for high extraction yield and high polyphenol content are longer extraction time and high solvent volume. According to the experimental results, the EY of KWZ continued to increase as X 3 , perhaps because the solvent volume increased diffusion and enhanced desorption of active part from prescription.…”

By using extraction yield, total polyphenolic content, antidiabetic activities (PTP-1B and α-glycosidase), and antioxidant activity (ABTS and DPPH) as indicated markers, the extraction conditions of the prescription Kursi Wufarikun Ziyabit (KWZ) were optimized by response surface methodology (RSM). Independent variables were ethanol concentration, extraction temperature, solid-to-solvent ratio, and extraction time. The result of RSM analysis showed that the four variables investigated have a significant effect (p < 0.05) for Y1, Y2, Y3, Y4, and Y5 with R2 value of 0.9120, 0.9793, 0.9076, 0.9125, and 0.9709, respectively. Optimal conditions for the highest extraction yield of 39.28%, PTP-1B inhibition rate of 86.21%, α-glycosidase enzymes inhibition rate of 96.56%, and ABTS inhibition rate of 77.38% were derived at ethanol concentration 50.11%, extraction temperature 72.06°C, solid-to-solvent ratio 1 : 22.73 g/mL, and extraction time 2.93 h. On the basis of total polyphenol content of 48.44% in this optimal condition, the quantitative analysis of effective part of KWZ was characterized via UPLC method, 12 main components were identified by standard compounds, and all of them have shown good regression within the test ranges and the total content of them was 11.18%.

Fermented Rhus verniciflua (FRV) as feed additives act as excellent anti-diarrheal drugs as they increase the intestinal absorption rate therefore being indirectly associated with enhancing growth performance and increasing digestibility in livestock. A total of 80 weaned pigs with an average initial body weight (BW) of 6.82 ± 1.11 kg were used to evaluate a diet supplemented with FRV meal in a 6 week feeding trial with two dietary treatments [CON-basal diet; TRT-CON + 0.2% FRV] on growth performance, apparent total tract digestibility (ATTD), blood profiles, fecal microflora, and fecal score. Our results showed that the dietary supplementation of FRV improved (p < 0.05) average daily gain and gain : feed (G : F) ratio during days 15-42 and the overall experiment period and also increased the ATTD of dry matter (p < 0.05) at days 14 and 42. On the contrary, there was no effect (p > 0.05) on average daily feed intake, ATTD of nitrogen and energy, and blood profiles during the entire experiment. Moreover, dietary inclusion of FRV significantly increased fecal Lactobacillus (p < 0.05) counts and reduced the diarrhea during days 22-42. Thus, the results suggest that FRV can be used as a potential additive to improve growth performance and dry matter and to reduce diarrhea while having beneficial effects on fecal microflora in weanling pigs.

“…Extraction methods have been reported for phenols and flavonoids of R. verniciflua Stokes [9,16,24,25] performed in terms of extraction solvent, time, sample amounts, and solvent volume (Table 4). Compared with the sample amount (5 g) used in the decompressing inner ebullition extraction process, sample amount used in the MSPD method (0.2 g) was much lower.…”

A simple and efficient matrix solid-phase dispersion via high-performance liquid chromatography coupled with a photodiode array detector was developed to analyze the following flavonoids of Rhus verniciflua Stokes: fisetin, fustin, butein, sulfuretin, garbanzol, and quercetin. The optimum conditions for the procedure was the use of Zeolite Socony Mobil-twenty-two molecular sieves as the adsorbent, sample:adsorbent ratio of 2:5, grinding for 3 min, and use of 8 mL of 70% methanol:water as the elution solvent. The method was validated for linearity, precision, reproducibility, limit of detection, and limit of quantification. The method exhibited excellent linearity for all six flavonoids. The intra-and interday precisions over a range of concentrations were below 3.0% and limits of quantification for the six flavonoids were 0.16 and 0.50 μg/mL. Compared with other published methods, the proposed method was more effective, rapid, and required less reagents. Therefore, the combination of matrix solid-phase dispersion and high-performance liquid chromatography coupled with photodiode array detector showed excellent reproducibility and simplicity and could be suitable for the extraction and quantification of multiple flavonoids in R. verniciflua Stokes samples.
