“Di-Huang” (Rehmanniae Radix) is a peculiar Chinese herbal drug, the fresh root named “Xian-Di-Huang” (“Xian” means fresh;the co.merce is now rarely available), mild-baking-dried raw roots “Sheng-Di-Huang” (“Sheng” means raw) and steam-processed “Shu-Di-Huang” (“Shu” implies steam-processed). The both kinds of herbal drug exert different efficiencies with different property acco.ding to the traditional clinical theory. It would be of interest that searching the clue of why the therapeutic functions of the same drug differ between the pre- and post-processing. To disclose the co.prehensive alteration of the iridoids, saccharides and phenylethanoids occurred between the raw and steam-processed “Di-Huang”, the HPTLC and HPLC chromatographic fingerprint analysis has been carried out. The results showed that in the raw crude drug, the iridoids like catalpol is the major bioactive co.ponents, and the oligosaccharides co.position kept rather co.sistent;however, in the steam-processed Di-Huang, iridoids was almost disappeared and the oligosaccharides were hydrolyzed gradually through the repeated steam-heating process. The worst case showed only fructose was detected with other minor residual co.ponents in the root tuber. It is due to presumably the unco.trollable steaming process in folk workshops. Defining reasonably the boundary between the “Sheng-Di-Huang” (mild-baking-dried Rehmanniae radix) and “Shu-Di-Huang” (steaming processed Rehmanniae radix) set up by chromatographic fingerprint pattern and standardizing the process would be necessary for assuring the co.sistent quality of the co.mercial herbal drugs.

The manufacturing techniques of a Cr-free co.t for non-oriented silico. steel sheets with excellent magnetic properties were developed. The ingredients of the co.t mainly include phosphate, epoxy resin, an amine solidified agent and water. Through the adjustment of ingredients, superior adhesiveness, co.rosion-resistance performance, welding performance and stamping preformance have been obtained. Thus ,the non-oriented silico. steel sheets with the above Cr-free co.t have been used successfully in the fields of co.pressors ,transformers, and small and medium motors.

To achieve a rapid and simple detection for the active ingredients of Aescin in the extraction process using near-infrared spectrosco.y (NIR) and to realize the state monitoring and quality co.trol of the extraction process. Partial least square regression (PLS) was applied to build the near-infrared calibration models, and the applicability of the model was investigated by predicting the unknown samples in the extraction process. The co.relation co.fficients of the established Aescin models (A, B, C, D) were 0.9836, 0.9831, 0.9833, 0.9824, and the prediction standard deviations (SEP) were 0.05636, 0.05043, 0.02412, 0.05636, respectively. This study suggests that the proposed model has superior stability and accuracy. NIR spectrosco.y technique provides a novel efficient and environmentally friendly approach to the rapid determination of four Aescin key quality indicators (A, B, C, D) in the extraction, which was solved the problem that the lack of state monitoring during the extraction of Aescin, thereby improved the quality of Aescin.

Estrogen is essential for the skin to maintain its physiological function. The binding of estrogen to the estrogen receptor (ER) activates gene transcription, which has biological effects on the target tissue. Estrogen levels and ER expression are known to decrease with aging and exposure to ultraviolet light (UV);therefore, increased estrogen levels and ER expression may improve age-related changes in the skin. Rehmannia root has been reported to have blood circulation-promoting and anti-inflammatory effects;however, few studies have reported the effects of Rehmannia root on skin. In this study, we examined the effects of Rehmannia glutinosa Libosch. var. purpurea Makino root extract (RE) on ER expression, and estrogen, RE, or their related ingredients increased ER expression in human epidermal keratinocytes, human dermal fibroblasts, and skin models. Moreover, RE increased the production of basic fibroblast growth factor, transforming growth factor β1, and epidermal growth factor. The mixture of estrogen and RE improved extracellular matrix (ECM) production to a greater degree than estrogen and RE independently. Although high population doubling levels (PDL) and UV irradiation downregulated ER expression, RE upregulated ER expression in high PDL cells and UV irradiated cells. In addition, RE increased the expression of epidermal differentiation marker proteins co.pared to their expression levels in the absence of RE. The co.lective findings suggest that RE aids in the prevention of skin aging by upregulating the ER expression that has been decreased by aging and UV and promoting estrogen activity, ECM production, and epidermal differentiation.

A newly designed microcapsule system to dramatically enhance solubility and stability of resveratrol was reported through solvent screening, surfactant and co.position optimization etc. Resveratrol solubility increased to about 550 times higher than that in pure water, the solution is co.orless and transparent, and HPLC results indicated that the resveratrol was stable under different temperatures （4 ℃, 25℃, 40℃, 48℃）： within four weeks, higher than 95.0% of resveratrol was retained after the thermal tests. It was also co.firmed that with the addition of the selected protective active, resveratrol retained about 90.0% after light radiation exposure for 24 hours. This microcapsule system may find high potential application for unstable and undissolved ingredients in co.metic products.
