Introduction of plant extracts

Plant extracts are concentrated substances derived from plants, typically using methods like distillation, solvent extraction, or cold pressing. These extracts contain the bioactive compounds found in plants, such as essential oils, alkaloids, flavonoids, terpenes, and more. They are used in a variety of industries including pharmaceuticals, cosmetics, food, and herbal medicine.

Here are some common ways plant extracts are obtained and their uses:

Methods of Extraction:

Solvent Extraction: This is one of the most common methods. A solvent, like ethanol or hexane, is used to dissolve the bioactive compounds, which are then separated from the plant material.

Steam Distillation: Often used for essential oils, steam is passed through plant material, causing the essential oil to vaporize. The vapor is then condensed and collected.

Cold Pressing: Used mostly for citrus fruits, this method involves pressing the plant material to extract oils or juices without heat.

Supercritical Fluid Extraction: A more advanced technique, this uses carbon dioxide under high pressure to extract plant compounds without heat, preserving the integrity of sensitive compounds.

Lavender Extract: Popular in aromatherapy, lavender is used for its calming, anti-anxiety effects, and in skincare for its antimicrobial properties.
