| 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. |

Two new epoxysteroids from Helianthus tuberosus.[Pubmed:21996718]
Molecules. 2011 Oct 13;16(10):8646-53.
Two new epoxy steroids, 5alpha,8alpha-epidioxy-22beta,23beta-epoxyergosta-6-en-3beta-ol (1) and 5alpha,8alpha-epidioxy-22alpha,23alpha-epoxyergosta-6-en-3beta-ol (2), and ten known steroids including (24R)-5alpha,8alpha-epidioxyergosta-6-en-3beta-ol (3), (22E,24R)-5alpha,8alpha-epidioxyergosta-6,22-dien-3beta-ol (4), (22E,24R)-5alpha,8alpha-epidioxyergosta-6,9(11),22-trien-3beta-ol (5), beta-sitosterol (6), sitost-5-en-3beta-ol acetate (7), 7alpha-hydroxysitosterol (8), schleicheol 2 (9), (24R)-24-ethyl-5alpha-cholestane-3beta,5alpha,6beta-triol (10), 7alpha-Hydroxystigmasterol (11), and stigmasterol (12) were isolated from Helianthus tuberosus grown in Laizhou salinized land of coastal zone of Bohai Sea, China. The structures of these compounds were unambiguously established by 1D, 2D NMR and mass spectroscopic techniques. The new compounds 1 and 2 exhibited weak antibacterial activity and no antifungal activity.
