Ultrasonic Cold Water Extraction of Psilocybin
Isolating psilocybin from fresh and dried fungi of the psilocybe species is known to be time-consuming and often quite inefficient. With ultrasonic extraction psilocybin, psilocin, baeocystin and norbaeocystin are rapidly extracted from fresh and dried psilocibe mushrooms. Ultrasonic extraction breaks the cell walls of the mushroom so that the bioactive substances are completely released, so that a highly efficient and rapid extraction process is achieved.
Ultrasonic Psilocybin Extraction
Ultrasonic extraction is used successfully in many industries such as food, pharmaceutical, cosmetic, and fine-chemical industry to extract and isolate bioactive compounds and other substances from raw materials. The ultrasonic technique is considered as highly efficient, rapid, reliable, safe and easy to operate as well as environmental-friendly extraction method. Due to these advantages, the ultrasonically-assisted extraction (UAE) outperforms alternative extraction methods. Compounds such as psilocybin, psilocin, baeocystin and norbaeocystin are already successfully extracted using Hielscher Ultrasonics equipment. The ultrasonic extraction of psychedelic compounds gives high yields of superior extract quality within a turbo-extraction procedure. Ultrasonic extraction is compatible with any solvent and allows for the production of full-spectrum extracts.
Ultrasonic Extraction – A Cold Extraction Technique
Bioactive compounds are heat-sensitive, which means they degrade and decompose under high temperatures so that they loose their effect and potency. Therefore, most botanical extraction benefit from a non-thermal extraction method, which is not based on heat a basic working principle. Ultrasonic extraction is a purely mechanical extraction technique, which working principle is the generation of acoustic cavitation.
What is Ultrasonic Cavitation and How does it Impact Extraction?
For instance, when a liquid is sonicated with an ultrasound probe at 20kHz, 20,000 vibrations per second are transmitted into the medium. The ultrasonic waves travel through the liquid, where they create alternating high-pressure (compression) / low-pressure (rarefaction or expansion) cycles. During the low-pressure vacuum cycle, minute vacuum bubbles or cavities occur in the liquid, which grow over several pressure cycles. During the compression phase of the liquid and bubbles, the pressure is positive, while the rarefaction phase produces a vacuum (negative pressure.) During the compression-expansion cycles, the cavities in the liquid grow until they reach a size, at which they cannot absorb more energy. At this point, they implode violently. The implosion of those cavities results in various highly energetic sonomechanical effects, which are known as the phenomenon of acoustic / ultrasonic cavitation. During the implosion of ultrasonic cavitation bubbles, extreme energy dense forces such as high shear, liquid streaming and turbulences are created in the sonicated liquid. These cavitational forces disrupt cell walls of plant tissues and release the intracellular compounds, including bioactive substances such as the hallucinogenics psilocybin, psilocin, baeocystin and norbaeocystin from mushroom species. The alternating high-pressure/low-pressure cycles also promote intense mass transfer rates, which results in the superior extraction yield obtained by sonication. Ultrasonic extraction can release the complete active substance content from botanicals.
Ultrasonic Psilocybin Extraction: Step-by-Step
You can extract psilocybin and other bioactive substances from mushrooms using water, ethanol or 200 proof ethyl alcohol as solvents.
Chop the fresh or dried psilocybin mushrooms into small bits and pieces. You can use caps and stems. Both contain the psychoactive compounds, however the caps consistently are richer in psilocybin. The spores do not contain psilocybin.
Place the chopped mushrooms in a glass beaker and fill it with cold water.
Optionally, you might place the glass beaker in an ice bath to keep the process temperature as cold as possible.
The sonicated slurry turn blue with blue water containing extracted psilocybin from the mushroom fruits.
Separate the mushroom pieces and debris by straining or filtering. Optionally, keep the mushroom material from filtration for a second extraction run using either water or ethanol.
Use an evaporation system to remove the solvent. 1 to 2 grams of dried magic mushrooms should yield in approx. 1cc of final extract. As mushrooms are a natural product, the content of psychedelic substances can vary.
Fill the final extract into a dark glass container or vial and store in the freezer.
By an optional crystallization step, the shelf-life of the psilocybin extract can be prolonged further.
- More complete extraction
- Higher yields
- Rapid process
- Cold extraction / Non-thermal process
- Compatible with any solvent
- Easy and safe to operate
- Low maintenance
Psilocybin can be found in more than 200 species of mushrooms of the four fungus genera Conocybe. Panaeolus, Psilocybe, Stropharia, which are all suitable for extracting the the active compound psilocybin ultrasonically. In general, mushrooms that contain psilocybin exhibit the following characteristics: They have dark spores, are lamella / gills fungi, grow mostly in humus-rich soil in meadows and woods of tropical and sub-tropical regions and exhibit blue bruises which occurs due to an oxidative reaction, when the mushroom is handled or damaged.
The most well-known species of psilocybin-containing mushroom is Psilocybe cubensis, which contains two psycho-active compounds, psilocybin and psilocin. Commonly known as shrooms, magic mushrooms, golden tops, cubes, or gold caps, Psilocybe cubensis belongs to the fungus family Hymenogastraceae, and was formerly known as Stropharia cubensis. As it is widely distributed and easy to cultivate, Psilocybe cubensis is the best-known pscilocybin-containing mushroom species.
Psilocybe cubensis is probably the most famous for its hallugcinogenic effects, which are caused mainly by the active compounds triggering psychedelic experiences after ingestion. Its major psychoactive compounds are:
- Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine)
- Psilocin (4-hydroxy-N,N-dimethyltryptamine)
- Baeocystin (4-phosphoryloxy-N-methyltryptamine)
- Norbaeocystin (4-phosphoryloxytryptamine)
Advantages of Ultrasonic Extraction Systems
The advantages of ultrasonic extraction are the high extraction yield of psychedelic compounds (i.e. psilocybin, psilocin, baeocystin, norbaeocystin), the free choice of solvent (e.g. water, ethanol, water-alcohol mixture etc.), as well as the simple and safe operation. Due to the intensive mechanical forces of sonication, ecological and mild solvents such as water, ethanol etc. are usually sufficient to achieve an extraordinary extraction rate and yield. As a result, ultrasonic extraction shortens the extraction time and enables a reduced use of solvents or the use of milder, gentler solvents. This means that ultrasonic extraction allows for both, higher extraction rates and healthier extracts (e.g. cold water extracts). Since the process temperature can be precisely controlled during the sonication, thermal decomposition of the extracts due to excessively high temperatures as well as evaporation of the substances are avoided.

Precisely Controllable Amplitudes for Optimum Results
All Hielscher ultrasonicators are precisely controllable and thereby reliable work horses in production. The amplitude is one of the crucial process parameters that influence the efficiency and effectiveness of ultrasonic extraction of bioactive phyto-nutrients and hallucinogenic compounds from botanicals. Raw material such as soft fresh mushrooms require milder sonication and lower amplitude settings, whilst dried mushrooms might require sonication at higher amplitudes to release the intracellular content. All Hielscher Ultrasonics’ processors allow for the precise setting of the amplitude. Sonotrodes and booster horns are accessories that allow to modify the amplitude in an even wider range. Hielscher’s industrial ultrasonic processors can deliver very high amplitudes and deliver the required ultrasonic intensity for demanding applications. Amplitudes of up to 200µm can be easily continuously run in 24/7 operation.

Facts Worth Knowing
Mushrooms, which contain psychoactive / psychedelic substances such as psilocybin, psilocin, and baeocystin, are known as psychedelic mushrooms, magic mushrooms, shrooms, magic truffles, and mush. More than 180 species of mushrooms containing psilocybin or its derivative psilocin are known.
Psilocybin mushrooms are illegal in many countries, e.g. USA, Canada, Europe, India. In the USA, they are classified as a Schedule I controlled substance, though recently, the FDA and DEA have allowed some small, highly controlled human studies on their potential for use in medical and psychiatric drug administration. The effects of psilocybin and other psychedelics have been researched for their effects and potential treatment of disorders such as cluster headaches, mood disorders, and addiction.
Psilocybe cubensis is one of the most popular magic mushrooms offering a medium psilocybin concentration of approx. 0.63% psilocybin and 0.60% psilocin in dried wild mushrooms. Indoor cultivated mushrooms mostly have higher concentrations of their active compounds.
|Psilocibe Species||% PSILOCYBIN||% PSILOCIN||% BAEOCYSTIN|
Psilocybin is an psychoactive, hallucinogenic substance found in mushrooms of the genera of Psilocybe, Panaeolina, Panaeolus, Copelandia, Conocybe, Gymnopilus, Stropharia and Pluteus and is considered as a narcotic drug.
Besides psilocybin, psilocin and baeocystin are two further active substances found in magic mushrooms.
The potency of mushrooms can vary greatly since mushrooms are a natural product, which develops in response to its environment. The various parts of mushrooms differ in potency, too (e.g. cap and stem may have a different concentrations of the psychoactive compounds). Due of these natural variations, the maceration, homogenization and ultrasonic extraction might help to reduce the risk of unexpectedly strong (or weak) doses of psilocybin.
Use and Effects: After administration of psilocybin, a wide range of subjective effects have been reported which range from feelings of disorientation, lethargy, giddiness, euphoria, joy, and depression. Approx. a third of users experience feelings of anxiety or paranoia. Low doses of the drug can induce hallucinatory effects, closed-eye hallucinations, and/or synesthesia (the experience of tactile sensations when viewing colors). At higher doses, psilocybin can induce the intensification of affective responses, enhanced ability for introspection, regression to primitive and childlike thinking, and activation of vivid memory traces. Open-eye visual hallucinations are common and can be very detailed although rarely confused with reality.
Anecdotal reports as well as recent studies suggest that a single administration of psilocybin can enhance reative thinking and empathy and could therefore be a potential treatment for cognitive and social behavior. Results of the study “Creative thinking and empathy” (Mason et al. 2019) indicate that psilocybin enhanced divergent thinking and emotional empathy the morning after use. Enhancements in convergent thinking, valence-specific emotional empathy, and well-being persisted seven days after use. Sub-acute changes in empathy correlated with changes in well-being. The study demonstrates that a single administration of psilocybin in a social setting may be associated with sub-acute enhancement of creative thinking, empathy, and subjective well-being.
