RESUMEN
OBJECTIVE: To optimize water extraction technology of Feng-Moutan Cortex. METHODS: L9 (34) orthogonal design was used to optimize soaking time, solid-liquid ratio, extraction time and extraction times in water extraction technology of Feng-Moutan Cortex using comprehensive scores for the peak area percentage and extract yield of 8 ingredients in Feng-Moutan Cortex as gallic acid, paeoniflorin, catechin, paeoniflorin, benzoic acid, benzoyloxypaeoniflorin, benzoylpaeoniflorin and paeonol after normalization as indexes. Verification test was conducted. RESULTS: The optimal water extraction technology was that 20-fold water, soaking for 1 h, extracting twice, 2 h each time. Results of verification test showed that comprehensive scores of 3 times of tests were 65. 98, 68. 85 and 69. 25, respectively. RSDs of each index were lower than 5％ (n=3). CONCLUSIONS: Established comprehensive scoring method can reflect the relative contents of effective components in Feng-Moutan Cortex comprehen- sively, so that optimized extraction technology is reasonable and feasible.
RESUMEN
<p><b>OBJECTIVE</b>To optimize the objective technical parameter for direct processing technology of fresh-cut for Paeonia Radix Alba.</p><p><b>METHOD</b>Peoniflorin and TGP were employed as the indexes of quality evaluation. Combining with the appearance of the slices, we investigated the influence of slice degree and thickness, drying temperature, drying time, drying method and other factors on the quality control of Paeonia Radix Alba slices. Furthermore, the key fresh-cut technology operating procedures parameter for Paeonia Radix Alba in Bozhou was established based on the semi-works production.</p><p><b>RESULT</b>It established tentatively the method for fresh-out and fresh-out after boiled of Paeonia Radix Alba as that selected fresh or beiled Paeonia Radix Alba, then divided them from different grades and put them into a roller to crash off the skin, cleaned and then dried them 9 h at 60 degrees C (water content 28% - 32%), and then moistened 2-3 h after spraying moderate water. Cut them into 1.5-2 mm decoction pieces and dried them at 60 degrees C, cooled, and sealed them in a package.</p><p><b>CONCLUSION</b>The industrialization of processing decoction pieces with freshly cut Paeonia Radix Alba is stable shortens processing time, avoids effectively sulfur fumigation and infiltrating and soften, and keep high quality of production.</p>
