The sapogenin wastewater was treated by adopting the technology of Pretreatment + aerobic digestion + coagulating sedimentation and oxidation decolor. The results showed that the COD fell from 12000mg/L to 600 and the chromaticity from 110mg/L to 50.COD removal rate could reached 99%.

该工程利用预处理+厌氧+好氧+混凝、脱色组合工艺处理黄姜废水，在进水COD和色度分别达12000mg/L和600倍的情况下，出水COD和色度分别为110mg/L和50倍，COD去除率达99%。

Saponins, steroid saponins, which are rich and play the most important physiologically active compounds in yam. The studies of steroid saponins of other plants found that glycone on saponins played an important physiological activity. Because of the structural differences between saponin glycosides with different forms and sapogenin resulting from the removal of glycone by hydrolysis on saponins , caused the different physiological effect.

山药含有丰富的皂，属类固醇皂，为山药所含最具生理活性的重要化合物；从其他植物类固醇皂的研究发现，醣基於皂的生理活性上扮演著相当重要的角色，其所接醣基的多寡与有无，醣基的组成、醣的键结型式、醣基链的长度及支链的有无等，皆会影响其生理功效；故不同形式配醣体的的皂，及水解后造成醣基去除而形成皂元，因其结构的不同，产生之生理功效亦不尽相同。

Because the sapogenin wastewater is highconsistency organic wastewater,we developed the twophase anaerobic digestion with three stages that acidification phase, inner electrolysis phase and methane phase.

开发了三阶段两相厌氧工艺即酸化、内电解、厌氧产甲烷的工艺处理皂素废水。从理论上分析了该工艺处理黄姜皂素废水的机理和优势。在实验条件相同时，改变内电解在工艺中的位置进行间歇式厌氧处理，测得2种厌氧工艺的处理效果。实验结果表明内电解在两相厌氧中间CODC r的去除率要优于内电解在酸化前

Yam steroid saponins and sapogenin are resulting in MCF-7 cells apoptosis by arrested the G0/G1 phase, increased the p53 protein with promoting apoptosis and decreased the AKT protein with anti-apoptosis and the BRCA-1 protein with repairing DNA. And, SPG has the excellent anti-cancer effect on MCF-7 cells may be due to induced much of the p53 protein in the early treated stage.

进一步的研究发现，山药固醇类皂及皂元抑制MCF-7乳癌细胞的功效，主要是诱发G0/G1期停滞，造成细胞凋亡；其透过的机制是经由p53促凋亡蛋白的增加，及AKT与BRCA-1等抗凋亡蛋白被抑制，达到双重细胞凋亡之抗癌效果；其中SPG处理之MCF-7肺癌细胞具早期大量诱发p53蛋白的特性，或许是SPG优异抗癌效果之原因。
