Thebaine content and Plant

Four varieties of thebaine-rich P. bracteatum grown outdoors on two seasons and distribution of thebaine in the aerial parts considered the most suitable raw material for commercial production to be determined. The leaves contain only 0-1 to 0-15%; capsules 0-5 to 3-0% and 28-53% latex bled. The maximum for the latter occurred about 3-4 weeks after the opening of the petals and during the day, at about 15.00 pm. A product 'bractium' just prepared as opium of P. somniferum contain up to 55% thebaine and calculations of the 1974 results provided theoretical yields of up to 58 k of thebaine per hectare. However, this method is very labor; more latex bled represents only 46% of the total thebaine of the capsule. Also contain significant amounts of thebaine stalks so that the seed heads can be recommended as a starting material. In the capsule of thebaine content peaked at 3 to 4 weeks after the opening of the petals and again two weeks later. At this stage, mature, there is a theoretical yield of 50 kg per hectare. Two other advantages result from the collection at that time mature seeds can probably be used for similar purposes in a poppy; and fruit walls at this stage does not contain thebaine bound '(i, e, thebaine insoluble in MeOH but soluble in acetic acid; NH4OH - linked in immature capsules thebaine 18-36% of the total thebaine represents. ). There is some evidence that, as these perennial increases in age, the ability of thebaine increase seems to continue production. Storage of the raw material, even under ideal conditions, resulting in a loss of thebaine between 12 and 20% in one year.
