The type of plant material (leaves, flowers, roots) being used determines which method of extraction will produce the best results. Some plant materials, like vanilla, which is difficult to extract, or jasmine flowers or rose petals, which are too delicate to survive the process of distillation, use another method to extract their aromatic essence, a process called solvent extraction.
Lab Alley sells coconut oil (MCT oil) in bulk 1 gallon, 5 gallon and 55 gallon containers to U.S. botanical tincture makers that manufacture edibles and topicals. Coconut oil has among the highest concentration of fatty acids (saturated fats). The surplus of these fatty acids in the coconut oil create a stronger binding agent for plant extracts.
Ultrasound-assisted extraction is a relatively straightforward strategy that can be used to enhance the efficacy of alcohol extraction methods. Hydrodynamic extraction technology has recently been introduced to the botanical industry, which utilizes a combination of temperature, pressure, and ultrasonication to create full spectrum herbal extracts from whole fresh flower.
Various plant extraction methods are used to remove specific compounds such as phytochemicals and antioxidants. Extraction methods include solvent extraction, distillation method, pressing and sublimation according to the extraction principle.
Steam distillation is one the most popular methods to extract essential oils such as oregano oil. Essential oils are natural aromatic extracts from plant material including grasses, leaves, flowers, needles, twigs, peels of fruit, seeds, bark, and roots. During the steam distillation process, the botanicals are placed in a still and pressurized steam is forced through the plant material. The hot steam forces open pockets aromatic compounds. The compounds escape from the plant material and evaporate into the steam. Sub-critical water extraction is another option for the selective extraction of oxygenated compounds from oregano.
A popular chemical extraction method is called the Soxhlet method. Soxhlet extractors use n-hexane as a solvent for extraction of oils and compounds from seeds. Soxhlet extraction is a very useful tool for preparative purposes in which the analyte is concentrated from the matrix as a whole or separated from particular interfering substances. Solvent extraction of solid samples, which is commonly known as solid–liquid extraction, is one of the oldest methods for solid sample pretreatment. Conventional Soxhlet extraction remains as one of the most relevant techniques in the environmental extraction field.
Different plant extraction methods recover live resins, distillates, concentrates, alkaloids, waxes, and essential oils. Methanol and ethanol are good solvents for plant extraction facilities that want to remove fats, raw/ crude extracts, lipids, chlorophyll, proanthocyanidins, biomolecules, lignins, plant-based extracts, flavonoids, cannabinoids, terpense, botanical extracts and polyphenols from plant materials and plant matrices.
Plant-based extracts, such as antioxidants, phytochemicals and polyphenols, are used in a number of end-markets, including cosmetics, foods and nutritional supplements. Plant extraction service companies and commercial extractors in the USA that make botanical products purchase solvents in bulk from Lab Alley. Lab Alley sells extraction grade solvents in 1 gallon bottles, 5 gallon pails, 55 gallon drums, 250 and 270 gallon totes.
Tetrahydrofuran has been explored as a miscible co-solvent in aqueous solution to aid in the liquefaction and delignification of plant lignocellulosic biomass for production of renewable platform chemicals and sugars as potential precursors to biofuels.
Solvents ordered from Lab Alley are highly effective chemicals that can extract important compounds from pant leaves, bark, buds, plant roots, fruits, berries, seeds, plant flowers and plant biomass.
