The conventional experimental techniques showed that ajmaline derived from Rouwolfia serpentina Benth. biomass grown in tissue culture was effective in arresting canine ventricular arrhythmias induced by coronary occlusion, strophanthin and epinephrine, displaying antiarrhythmic effects in aconitine-induced intoxication of rats and substantially elevating the threshold of ventricular fibrillations in cats. The antiarrhythmic activity of ajmaline produced by the biotechnological technique was identical to that of ajmaline derived from the natural root of Rauwolfia serpentina Benth, which allows one to recommend that the agent in question should be clinically tested as an antiarrhythmic.

Monoterpenoid indole alkaloids (MIA) are one of the largest and most complex alkaloid class in nature, boasting many clinically significant drugs such as anticancer vinblastine and antiarrhythmic ajmaline. Many MIAs undergo nitrogen -methylation, altering their reactivity and affinity to the biological targets through a straightforward reaction. Remarkably, all known MIA -methyltransferases (NMT) originate from the neofunctionalization of ancestral γ-tocopherol -methyltransferases (γTMTs), a phenomenon seemingly unique to the Apocynaceae family.

Article Synopsis
- Rauvolfia serpentina roots are used in Southeast Asian herbal medicine for various ailments including snake bites, fever, hypertension, and dysentery.
- The study evaluated the content of key active ingredients (reserpine, ajmaline, and ajmalicine) in the roots processed using different methods on plants cultivated in Japan.
- Results showed that a 30-minute drum mixer washing method is efficient for root processing, and active ingredient content is consistent across different root sizes, indicating uniform quality of the crude drug.

Electronic address:
Eleven undescribed monoterpenoid bisindole alkaloids, alstomaphyines A-K (1-11), along with three known analogues were isolated from the leaves and stem bark of the Alstonia macrophylla. Compounds 1-3 were unprecedented dimerization alkaloids incorporating a macroline-type motif with an ajmaline-type motif via a C-C linkage. Their structures and absolute configurations were elucidated by extensive spectroscopic analysis, electronic circular dichroism (ECD) calculation, and CD exciton chirality method.
