Once you have done this process to your whole leaf once, it cannot be done again without excessive black wax. There is probably 15 to 20% of the salvinorin still left in the leaf, you can make a much longer soak to get the remaining out, but it won't be nearly as clean. You can dry it and try it again later, but be warned that you will get lots of waxes.

Caution:
Be sure that your enhanced leaf is completely dry with no hint of Acetone smell before you attempt to use any of it! Drying might be accomplished in open air by spreading it out into a thin layer in a glass pan for 24 hours. Don't heat it in the oven, as this could ignite the acetone vapors. In fact it is a good idea to have a well ventilated outdoors spot to evaporate off the acetone. I have found that salvinorin can be destroyed at much lower temperatures than what is commonly stated in different information sources on the net. Especially when in solvent. If you must heat it, keep it at or below 100 F. This may seem extreme, but I have seen the salvinorin crystals disappear out of solvent to never reappear when heated to only 140 degrees F.

Don't get this extract on your hands and touch your face, it can cause skin to puff up, turn red and then dry in sensitive individuals. Soap and water will not cut it, you must wash your hands with solvent to remove it.

Cleaning up your extract:
It should not be necessary to further clean your extract when using the above process. However, there are a few additional steps that may be desirable to some persons. The extract can be further cleaned or refined by using just Naphtha, or Rosinol lighter fluid. Naphtha is superior to any other solvent when used to clean up an extract from this process because salvinorin is almost insoluble to Naphtha (compared to other solvents) and the green or non-salvinorin portion of the extract is extremely soluble to Naphtha. Although the extract from the above process is pure enough as it is, a Naphtha clean up can yield some very white salvinorin. (When doing very short extractions with cold acetone, a follow up cleaning step such as this is generally not needed in order to achieve crystalline salvinorin.)

When I did my first extraction using this method with 200g of leaf, I had let the extract completely dry and then put all of my dry crusty crystalline extract into about 30 ml of Reagent Grade Methanol. Immediately, the Methanol took on a dark green color and I could see crude salvinorin that contained lots of small crystals fall to the bottom of the container. Because of this, it was obvious that I had some highly purified extract to begin with. Although Methanol will work fine to remove the green, I should have used Naphtha instead of Methanol because salvinorin is far less soluble to Naphtha. This way, I loose less of the salvinorin to the solvent when I later pour it off from the salvinorin concentrate laying in the bottom of the container.

Naptha is also used in a process called partitioning (washing). It is used to clean up extremely impure extracts that contains so much chlorophyll that the extract appears to be made of black wax. This is the kind of extract that you will get if you try to extract from powdered leaf for more than just a few seconds with either Acetone or Isopropyl. You can also get it if you soak whole leaf in either of these solvents at either room temperature, or for too long a period of time. If you were to use the partition process to clean up a Salvia Divinorum extraction, you would first completely dry your extract out and then reconstitute it with 100% Methanol. Then, after completely dissolving your extract in it, you would mix the Methanol with an amount of water that would add 20% to its total volume (80% Methanol, 20% water). This is then mixed with an equal volume of Naphtha inside of a glass container called a separatory funnel. A separatory funnel is just a cone shaped seala! ble glass container that has a drain valve on the bottom. The partitioning process is used to remove an undesired component of one solvent by transferring it into the other. The whole sep funnel with its two layers of solvent is agitated, or shaken, to get the two solvents to temporarily mix together, something that they normally won't do. The solvents will separate into two distinct layers again, which could take several hours, days, or longer. The bottom layer of solvent is then removed and saved by opening the valve in the bottom of the container. The lower layer of fluid is the one you want to keep. You then evaporate off all of the Methanol and you should have a much nicer extract, at a cost, since you will loose some of the salvinorin to the naptha.
