RESUMEN
In this paper, the extraction rate of crude polysaccharides and the yield of polysaccharides from Hippocampus served as test indicators. The comprehensive evaluation indicators were assigned by the R language combined with the entropy weight method. The Box-Behnken design-response surface methodology(BBD-RSM) and the deep neural network(DNN) were employed to screen the optimal parameters for the polysaccharide extraction from Hippocampus. These two modeling methods were compared and verified experimentally for the process optimization. This study provides a reference for the industrialization of effective component extraction from Chinese medicinals and achieves the effective combination of modern technology and traditional Chinese medicine.

Two new oleanane-type triterpene glycosides, phytolasides A (1) and B (2), and six known ones (3-8), were isolated from Phytolacca acinosa fruit fermentation broth. Their structures were elucidated by HR-ESI-MS and 1 D- and 2 D-NMR spectroscopic methods. Antiproliferation of compounds 1 and 2 against HepG2 cells was examined by using CCK8 assays.
