Unlocking the therapeutic potential of Perilla frutescens through advanced molecular extraction.
Perilla Leaf Extract, derived from the leaves of Perilla frutescens (L.) Britt., has emerged as a cornerstone ingredient in the global functional food, dietary supplement, and cosmetic sectors. Renowned for its rich concentration of polyphenols, flavonoids, and essential volatile compounds, this botanical extract offers profound anti-inflammatory, anti-allergic, and antioxidant benefits.
As leading China Perilla Leaf Extract Manufacturers, we utilize state-of-the-art extraction technologies to isolate and standardize the key active compounds. The primary therapeutic markers of Perilla Leaf include Rosmarinic Acid, Luteolin, and Apigenin. These bioactives work synergistically to modulate immune responses, inhibit histamine release, and neutralize free radicals, making it an exceptional natural alternative for seasonal respiratory comfort and dermatological health.
Key Active Compound Focus: Rosmarinic Acid
Rosmarinic acid is a natural polyphenol antioxidant carboxylic acid. In Perilla Leaf Extract, it acts as the primary marker for quality control. It exhibits potent anti-inflammatory properties by inhibiting cyclooxygenase (COX) and lipoxygenase (LOX) pathways, thereby reducing the synthesis of inflammatory prostanoids.
| Specification Parameter | Standard Range | Testing Method |
|---|---|---|

| Luteolin Content | ≥ 0.5% - 5.0% | HPLC |
| Appearance | Fine Yellow-Brown to Greenish Powder | Visual |
| Solubility | 100% Water Soluble (Food/Beverage Grade) | Visual |
| Heavy Metals | ≤ 10 ppm (Pb ≤ 2ppm, As ≤ 1ppm) | ICP-MS |
| Pesticide Residues | Compliant with USP <561> / EP standards | GC-MS/LC-MS |
Why leading brands are integrating Perilla Leaf Extract into their product pipelines.
With rising consumer wariness toward synthetic antihistamines and their side effects (such as drowsiness), Perilla Leaf Extract is highly sought after as a clean-label, natural alternative for seasonal allergy relief and respiratory support formulations.
Due to its high concentration of rosmarinic acid, Perilla extract serves as a potent natural antimicrobial and antioxidant preservative in clean-label food, beverage, and cosmetic products, extending shelf life without synthetic additives.
In skincare, Perilla Leaf Extract targets inflammatory pathways associated with acne, eczema, and premature aging. Brands utilize it in soothing serums, redness-relief creams, and UV-protection formulations.
How we preserve molecular integrity from raw botanical to standardized powder.
At Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB), we employ a multi-stage, low-temperature extraction process designed to maximize the yield of volatile actives and polyphenols while preventing thermal degradation.
1. Sustainable Sourcing: We source premium *Perilla frutescens* leaves from GAP-compliant cultivation bases in China, ensuring strict control over soil quality, pesticide usage, and heavy metal accumulation.
2. Low-Temperature Water/Ethanol Extraction: Utilizing advanced countercurrent extraction technology, we optimize solvent ratios to selectively target rosmarinic acid and luteolin, preserving their biological activity.
3. Membrane Filtration & Concentration: We utilize ceramic membrane filtration to remove high-molecular-weight impurities, followed by low-temperature vacuum concentration to protect heat-sensitive compounds.
4. Spray Drying & Granulation: Our cleanroom spray drying processes generate highly uniform, free-flowing powders with excellent water solubility and stability, suitable for direct compression, encapsulation, or liquid formulations.
