Dear Forum members,
I have to check some nutritional supplements and cosmetic creams for the presence of DHEA (dehydroepiandrosterone) and / or diosgenin. DHEA should be no problem at just 50 % or so of acetonitrile on a C18 column (UV at 210 nm). Diosgenin, a larger steroidsaponin, seems more difficult. Does any of you have any experience with analysing diosgenin in nutraceuticals or Wild Yam (Dioscorea species) ? Preferably LC-UV.
Thanks
Jan
