Indoline Alkaloids of intermediate basicity: Reserpiline, Ajmaline, Iso- Ajmaline, rauwolfinine are tertiary Indoline alkaloids. 3. Strong Anhydronium Bases: Serpentine, serpentinine and alsotonine are strongly basic anhydronium alkaloids.

Reserpine is the most important alkaloid present in root, stem and leaves of the plant. It contains not less than 0.15% of Reserpinerescinnamine group alkaloids, calculated as Reserpine. The percentage of alkaloid depends on geographical place from where the plant is collected and also the season of collection. Generally samples from Assam have a higher percentage of alkaloid (2.57%) and December is the best month for the collection for getting more percentage of alkaloid.
