Plant Extracts

What is Plant Extracts?

Plant extracts are concentrated substances obtained by treating plant tissues with specific solvents or methods (like freeze-drying) to extract bioactive compounds [1, 6]. These extracts capture the plant's essential nutrients, flavors, or medicinal properties.

Plant Extracts Types

The market offers diverse types categorized by form and extraction method:

• By Form: Includes powders, liquids, and high-stability freeze-dried extracts [6].

• By Standardization: Consists of standardized extracts (guaranteed levels of active markers) and ratio extracts.

• By Source: Derived from fruits, leaves, roots, or flowers [5].

• Specialty Types: Includes essential oils, oleoresins, and herbal distillates.

Quality Control of Plant Extracts

Quality is defined by using the correct species and plant part, ensuring the product is unadulterated and safe for consumption [5]. Key measures include:

1. Identity Testing: Verifying botanical origin.

2. Purity Checks: Screening for microbial contamination, heavy metals, and pesticides [10].

3. Regulatory Compliance: Adhering to standards like the Lacey Act or dietary supplement regulations [3, 8].

• Food & Beverage: Used as natural colorants, flavors, and preservatives [10].

• Pharmaceuticals & Supplements: Serve as active ingredients in herbal medicines and dietary supplements [8].

• Cosmetics: Valued for antioxidant and skin-soothing properties.

• Agriculture: Utilized in eco-friendly farming and organic pest control [4].
