Last 100 gram run yielded 100mg

ingredients as follows:
i contacted the vendor of the cactus chips and he tells me they are dried outer flesh of peruvian torch
im using hydrate lime - calcium hydroxide
d-limonene is a mix of R and S phases
5% acetic acid distilled vinegar for salting
being evap'd in a food dehydrator at 155F
method
mixing lime and poswdered bark well adding the 300 mls of water leaving to sit for an hour before adding 300ml d-limonene, stirring well. then occasional stirring over the next 3 hours. limonene is removed filtered into seperatory funnel and 25ml of distilled vinegar added rolled for 5 minutes and repeated 3 times. fresh limonene was than added to the cactus mixture and the process repeated. 3 Limonene soaks in total and 4 vinegar washes on each one.
i even tried several strong shakes on spent limonene to see if i was not salting effectively and nothing came out. the only conclusions i can draw are the alkaloids just arent making it out into the limonene, or there not in there in the first place and the cactus is no good. im going to order from a different supplier and see if results are better. as i know im not messing the process up in any way as far as i can tell.
