I generated some data, which to my knowledge, is the first ms data (or any analytical data) for these particular variety of seeds. I compared against I.tricolor var. "heavenly blue". The masses were within two mass units of lysergol standard.
The heavenly blue seeds were considerably larger, about triple the size. All samples were ground with mortar and pestle, 710 mg transferred to 15 mL conicles, with 7.1 mL methanol, and vortexed for a min, filtered through 0.22 um syringe filters to 2 mL autosampler vials.

I've searched everywhere for data on I.cordatotriloba, it's not even referenced in The Encyclopedia of Psychoactive Plants.

Will upload the MS data, and perform FLD and CAD analysis.

According to this study: https://www.nature.com/articles/s42003-021-02870-z or atleast the attached diagrams they do not contain ergot alkaloids. I would not be surprised if such a large study contains inaccuracies.

But very interested to see your results benzyme.

ahh nice...such a recent study too. Thanks.

this is preliminary data, and will be an ongoing study.
I overloaded the detector with lysergol standard (oops), it really sticks to the column. No cross-contam was performed, all samples were dissolved in HPLC-grade methanol.

I ground up the tievine seeds first, added methanol, and transferred to an autosampler vial. The MG seeds were treated the same, and used as a suspected known. Lysergol was a dark beige powder, and ~1mg was added straight to an autosampler vial with methanol. All samples were filtered with new 0.22 um ptfe syringe filters.

Those results look very promising benzyme.
So ipomoea cordatotriloba appears active lookimg at the MS data. In addition, it's a more cold hardy ipomoea. If it has decent percentage of ergine alkaloids this could be a better species to grow for those in colder climates.

thanks
I also have that one on my shelf. It really is an indespensible read, incredibly useful.

Benzyme, will you be able to calculate a rough percentage?

yes, with CAD detection, I could run a comprehensive purity profile (that detection method shows everything). FLD, to some extent (in the UV domain), would as well.

I ran a 3D-excitation scan, from 260 nm to 330, 450 nm emission. The results were curious. The tievine main component eluted earlier than the lysergol standard, and had peak excitations around 292 nm, 304, and 320.. I need to run an erlich's test to screen for indolic compounds; if it gives a purple hue, it may contain some clavine compound.

Thanks for sharing your ongoing experiment, please do let us know the final results!

Are we seeing two co-eluting substances in the tievine extract there?

What about the MG extract, what is the minor peak?

Any updates Benzyme?
