Because I do. And I had a tiny bit of time to try some things out. My current stack consists of Follidrone and Dermacrine (among others), and I know there's this whole thing with the NY attorney general and herbal supplements, so what I decided to do was to throw some of the supplements I'm currently taking down an LC-MS.
I had some trouble solubilizing follidrone, which I imagine was due to the rice flour or other excipients, but just added mixture of MeOH/water and filtered through cotton in a glass pipette.
Running on positive ion mode, C18 column, H2O:ACN solvent system
Epicatechin molecular weight = 290.27.
Since it's positive ion mode, I'm looking for Mass+1, so 291.27.
The middle red line is the Total Ion Current (TIC) for the entire run and the bottom red line is the mass spec for the retention time of 0.84 min. The top purple line is a search for the mass of 291.2 through the entire run. Sure enough, it hits at ~0.84 min.
In case you're wondering what it all means, there is epicatechin in follidrone and it looks like it's pretty darn pure (if I had time and effort, I would love to run an HPLC, since LC-MS occasionally doesn't tell you the entire story of a sample, whereas HPLC would. Also, I would love to run an NMR of follidrone alongside an internal standard to determine actual amount of epicatechin in each dose. Is it really 500mg?)
Next I ran Dermacrine, sample made up in MeOH, same mobile/stationary phase conditions
DHEA mw = 288.42
Preg mw = 316.4
Masses hit for 290 and 317, at 2.07 min and ~3min, respectively. I really could see 317, but the signal was really low. I'm sure I'm testing the lower limits of detection since I already diluted the sample pretty good. (If you're wondering why I chose 290 to search instead of 289 (M+1), the signal was stronger for 290, but 289 was there. Just wanted to make sure the peak was being seen.)
tldr: Follidrone contains epicatechin and Dermacrine contains DHEA with a small amount of Pregnenolone, per label facts.
