Plant extracts are products derived from plants through an extraction and separation process, aimed at obtaining specific components without altering the original plant's composition. They can be classified into different types based on the extraction process and quality. Some common categories include simple extracts, quantitative extracts, standardized extracts, and purified extracts. Plant extracts can take the form of solid extracts, liquid extracts, or soft extracts, depending on their intended use and formulation.

Applications of plant extracts

One of the applications of plant extracts is as natural colorants. Various parts of plants such as roots, stems, leaves, flowers, and fruits can be used to produce organic pigments through extraction, separation, refining, and drying processes. Examples of natural pigments include capsicum red pigment, marigold extract, gardenia yellow pigment, and curcumin.

Plant extracts are also utilized as natural sweeteners. These are obtained by extracting and processing sweet components from plants and can be classified into low-intensity sweeteners like sucrose and beet sugar, and high-intensity sweeteners like steviol glycosides, mogrosides, sweet tea glycosides, licorice extracts, and neohesperidin dihydrochalcone. The trend in the food and beverage industry is shifting towards replacing sugar with natural high-strength sweeteners.

Moreover, plant extracts have been found to possess various health functions, leading to their use in health foods. Examples of health functions associated with specific plant extracts include immune enhancement (e.g., ginseng and cordyceps extracts), blood lipid reduction (e.g., tartary buckwheat and dandelion extracts), antioxidant properties (e.g., grape seed extract), memory improvement (e.g., Ginkgo biloba and fenugreek extracts), and many others.

Chinese medicine formula granules also incorporate plant extracts. These granules are made from single Chinese medicine decoction pieces, extracted through water extraction, concentration, drying, and granulation. They serve as a supplement to traditional Chinese medicine decoction pieces.

Furthermore, traditional Chinese medicine extraction raw materials are extracted and separated from traditional Chinese medicinal materials or natural plants. They contain a single active ingredient with a clear pharmaceutical active ingredient, typically with a content of over 90%, and have a drug approval number. Standardized Chinese medicine extracts refer to various vegetable oils and extracts included in the Chinese Pharmacopoeia.

Finally, plant essential oils are aromatic oily liquids extracted from plants, with about 300 known to have significant commercial value out of over 3000 known varieties. Plant essential oils are used in various industries, including perfumes, cosmetics, medicines, food and beverages, pest control, and more. China is a major producer and exporter of raw materials for Litsea cubeba essential oil, accounting for a significant portion of the international market.


In conclusion, plant extracts are versatile and valuable sources used in medicine, food, cosmetics, and various industries. Their wide range of chemical compounds offers numerous potential benefits, and ongoing research continues to uncover even more applications. Embracing the power of plant extracts not only enhances our health and well-being but also promotes sustainability and environmentally-friendly practices.
