You might search the web for my paper "Empathogenic Effects of Sceletium tortuosum" ('authored' by by Groot van der Gross) which also details history and a little bit about the alkaloids.
Nice to see there are still people interested in the research into new mesembrine containing plant species.
I still have the occasional ongoing converstation with Dr. Nigel Gericke about new mesembrine sources we have recently identified, but neither of us has been active in this field for a while.
However, research indicates there is definitely a usable quantity of mesembrine in the foliage and stems of most of these plants, so destroying them for the roots is unnecessary.
k trout and I had some interesting conversations regarding certain Delospermas and their suspected mesembrine content a few years back, if memory (always in question these days) serves me well.
Lately, most of my research energies have been directed into the Nymphaeas.
Dr. Nigel Gericke is a white medical doctor south african who patented [along with 4 others mesembrine]]and used to grow it on his farm before being bought out of his patent 1/4 part so not the best guy too quote as for objectivtiy.
