Over 25 alkaloids have been isolated from Kratom. The most abundant alkaloids consist of three indoles and two oxindoles. The three indoles are mitragynine, paynanthine, and speciogynine - the first two of which appear to be unique to this species. The two oxindoles are mitraphylline and speciofoline. Other alkaloids present include other indoles, and oxindoles such as ajmalicine, corynanthedine, mitraversine, rhychophylline, and stipulatine.

The alkaloid content of the leaves of Mitragyna speciosa is about 0.5%, about half of which is mitragynine. An average leaf weighs about 1.7 grams fresh or 0.43 grams dried. Twenty leaves contain approximately 17mg of mitragynine. All leaves appear to contain mitragynine, speciogynine, paynanthine, and small quantities of speciociliatine. Oxindole alkaloids usually occur only in small or trace amounts.

Alkaloid content varies from place to place and at different times. Within each location, there is a quantitative variation in alkaloid content from month to month. While indole content seems to be fairly stable, oxindole content shows tremendous variation.

Results of quantitative analysis of Kratom done by MJB Botanicals for this product is an average of 300mg alkaloids per 25gm
