The captivating aromas and therapeutic benefits of essential oils are a testament to the intricate processes that transform plant life into potent botanical essences. At NINGBO INNO PHARMCHEM CO.,LTD., we believe in the transparency of our methods, from sourcing the finest raw materials to the careful extraction of our natural plant extract essential oils. Understanding these essential oil plant extract extraction methods is key to appreciating the quality and efficacy of the final product.

One of the most common and traditional methods is steam distillation. This technique involves passing steam through plant material, causing the volatile aromatic compounds to evaporate. The steam and oil vapor mixture is then cooled, condensing back into liquid form, from which the essential oil can be separated from the water (hydrosol). This method is highly effective for many aromatic plants and is considered a high-yield process.

Cold pressing, also known as expression, is primarily used for citrus fruits. The peels of fruits like lemons and oranges are delicate and sensitive to heat. This method involves mechanically pressing the peels to rupture the oil sacs and release the essential oil. It’s a swift process that avoids thermal degradation, preserving the bright, fresh aroma and therapeutic properties characteristic of citrus oils. This method is crucial for maintaining the integrity of the volatile oils.

Solvent extraction is a more complex process used for delicate plant materials that cannot withstand steam distillation or cold pressing, such as jasmine or rose. In this method, a solvent, commonly hexane, is used to extract the aromatic compounds, resulting in a waxy substance called a 'concrete'. This concrete is then further processed with alcohol to remove the solvent and yield a highly concentrated 'absolute'. Absolutes are intensely fragrant and are often used in fine perfumery.

CO2 extraction utilizes carbon dioxide under specific temperature and pressure conditions to extract aromatic compounds. When CO2 is in a supercritical state (neither fully liquid nor gas), it acts as an efficient solvent, selectively extracting the desired compounds. This method is known for its ability to produce oils that are very close to the natural composition of the plant, without leaving any solvent residue.
