Abstract

The invention discloses a method for extracting curcuma steroid saponin, which comprises the following steps: S1, cleaning and pulping by a cleaning and pulping device to obtain turmeric pulp; s2, performing short-time fermentation on the mixture, and improving the mixing capacity with water through sodium dodecyl sulfate; s3, adding an aspergillus niger suspension, and carrying out secondary fermentation; and s4, adding excessive iron powder to generate ferrous gluconate, removing sodium dodecyl sulfate, separating through a super-oleophobic filter membrane to obtain a curcuma steroid saponin crude substance and a ferrous gluconate solution, and respectively refining to obtain curcuma steroid saponin and ferrous gluconate. The curcuma steroid saponin extracted by the method is high in yield, no acid or organic solvent is added, pollution to the environment is avoided, green extraction is truly realized, meanwhile, starch is converted and utilized to generate ferrous gluconate, and efficient utilization of the starch is realized.

Description

technical field [0001] The invention relates to the field of steroidal saponin extraction, in particular to a method for extracting curcuminoid steroidal saponin. Background technique [0002] Turmeric, scientifically known as Dioscorea shield leaf, is a unique medicinal plant resource in my country. Turmeric is mainly used to produce turmeric saponin, which can be used to synthesize hundreds of steroid hormone drugs, known as "medicinal gold". Turmeric saponin is present in the rhizome of turmeric in the form of turmeric steroidal saponin, and turmeric steroidal saponin is an amphiphilic compound that is connected with a sugar group at the C3 and C26 positions of turmeric saponin, and the turmeric aqueous suspension is usually industrially All the components in the turmeric are acid-hydrolyzed together to produce turmeric steroidal saponins, and there are bottlenecks such as "large pollution, low yield, and high cost". In addition, turmeric rhizomes also contain a large am...
