This product originated from 500 grams of Mitragyna Speciosa leaf material, yielding a resin extract of around 25 grams which is then cleaned before sale leaving a total yield of approximately 15 grams. This resin is not the same as the water based extracts offered by many other vendors. An outside lab has tested this 50% extract, showing it to contain 54% total alkaloids; 17% pure mitragynine with 1-2% being 7-hydroxy-mitragynine.
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.
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.
