Smilax saponin B - Reference Information
| Distribution | Steroidal saponins are a class of sterol compounds containing 27 carbon atoms as aglycones and oligosaccharides. They are widely distributed in nature, mainly concentrated in Lilies, Dioscoreaceae and Agave plants, with Dioscoreaceae and Dioscoreaceae being the most concentrated. |
| structure | structurally can be divided into spiral sterane type, furansterane type and cholesterane type. furansterane saponins are a kind of important steroid compounds, mostly disaccharide saponins in structure, usually attached to sugar chains at C3 and C26 positions of aglycoins, its representative compound is methyl prodiosgenin, which was first isolated from the rhizomes of fresh Dioscoreaceae plants in 1974. Methyl prodiosgenin usually exists in a variety of Dioscoreum plants together with diosgenin In addition, it also exists in the seeds of Smilax, asparagus and fenugreek. |
| biological activity | Methyl protodioscin is a kind of steroid diglycoside with anti-tumor activity, which can induce cell cycle arrest. |
| use | used for content determination/identification/pharmacological experiments, etc. |
