| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Steroidal saponins from Dioscorea panthaica and their cytotoxic activity.[Pubmed:15125576]
Pharmazie. 2004 Apr;59(4):294-6.
A new steroidal saponin, Dioscoreside E (1), and a known compound, protodioscin (2), were isolated from an ethanol extract of the rhizomes of Dioscorea panthaica. The structure of 1 was established as 3-O-[bis-alpha-L-rhamnopyranosyl-(1 --> 2 and 1 --> 4)-beta-D-glucopyranosyl]-26-O-beta-D-glucopyranosyl-20(R)-methoxy-25(R)-furosta- 5,22(23)-diene-3beta,26-diol, on the basis of spectral and chemical evidence. Compounds 1 and 2 showed cytotoxic activity against a panel of tumor cell lines.
New furostanol glycosides from the rhizomes of Dioscorea futschauensis R. Kunth.[Pubmed:14604232]
J Asian Nat Prod Res. 2003 Dec;5(4):241-7.
Two new furostanol glycosides, 26-O-beta-D-glucopyranosyl-3beta,26-dihydroxy-23(S)-methoxyl-25(R)-furosta-5,20(2 2)-dien-3-O-alpha-L-rhamnopyranosyl(1 --> 2)-[beta-D-glucopyranosyl(1 --> 3)]-beta-D-glucopyranoside (Dioscoreside E, 1) and 26-O-beta-D-glucopyranosyl-3beta,26-dihydroxy-25(R)-furosta-5,20(22)-dien-3-O-alp ha-Lrhamnopyranosyl(1 --> 2)-[beta-D-glucopyranosyl (1 --> 3)]-beta-D-glucopyranoside (prtotogracillin, 2), together with 11 known furostanol glycosides were isolated from the rhizomes of Dioscorea futshauensis R. Kunth. Their structures were elucidated on the basis of spectroscopic analysis (NMR and FABMS). Their anti-fungal activity against the plant pathogenic fungus Pyricularia oryzae and cytotoxic activity on K562 cancer cell line were evaluated in vitro.
