1.Optimization of Processing Technology of Nine Steaming Nine Drying of Rehmannia glutinosa by Multiple Indexes Comprehensive Balance Method-Orthogonal Test
China Pharmacy 2016;27(7):962-965
OBJECTIVE:To optimize the processing technology of nine steaming nine drying of Rehmannia glutinosa. METH-ODS:L9(34) orthogonal experimental design was adopted to investigate the effects of the amount of added wine,steaming time and drying way on processing technology using the content and property of 5-hydroxymethyl furfural,acteoside,reducing sugar wa-ter extract,and character score as indexes. Comprehensive balance method was used for result evaluation,and optimized technolo-gy was validated. RESULTS:The optimized processing condition was as follows as the amount of added yellow wine 40%,steam-ing for 9 times,lasting for 6 h each time,blast drying at 70 ℃. Average value of each factor in validation test was 4.030 mg/g, 0.117 mg/g,0.376 7 g/g,0.733 g/g and 9.0 points,respectively. Their RSDs were 1.78%,2.9%,1.54%,2.13% and 0.1%(n=3). CONCLUSIONS:Optimized technology is reasonable and controllable in product quality,and can provide reference for quality control study of nine steaming nine drying of R. glutinosa.

The aim of this research is to investigate the influence of microencapsulation on the expression of the oxidative stress genes and exogenous regulation of HepG2 cells. We compared the expression of hemeoxygenase-1 (HO-1) and glutathione S-transferases-A1 (GST-A1) in HepG2 cells under different culture conditions through real-time PCR. The effects of exogenous antioxidants on cell viability and albumin levels were also evaluated through MTT assay and ELISA assay. The results showed that after culturing for 6 and 16 days, the expression levels of HO-1 in encapsulated cells were approximately 4.9 and 3.1 times higher than that of monolayer cells at the same culture period; As for the expression levels of GST-A1, they were elevated to 11.2 and 33 times of monolayer cells (P < 0.05). Accordingly, we found that NAC at 5-10 mmol/L significantly increased the viability by 40%-70% and the biosynthetic function by 20%-30% in microencapsulated HepG2 cells (P < 0.05). GSH increased the viability of the encapsulated cells by 20%-55% and the biosynthetic function by 15% (P < 0.05). In conclusion, oxidative stress exists in the microcapsules and affects genes expression. Exogenous antioxidants can prevent the inhibition effects of oxidative stress on cellular growth.
