Introduction to Psoralea Corylifolia Extract
Psoralea Corylifolia Extract is a highly valued botanical raw material derived from the mature seeds of Psoralea Corylifolia Linn., a leguminous plant traditionally cultivated across parts of Asia, including India and China. For centuries, the seeds of this plant—commonly known as "Buguzhi" in Traditional Chinese Medicine—have been recognized for their broad spectrum of bioactive compounds. The extract is standardized primarily on its furanocoumarin content, most notably psoralen and isopsoralen (also referred to as angelicin derivatives), which serve as the principal markers for quality control and potency.
The Extract Factory specializes in supplying pharmaceutical-grade and food-grade Psoralea Corylifolia Extract to formulation developers, supplement brands, cosmetic manufacturers, and wholesale distributors worldwide. Our product portfolio spans multiple specification grades—including 10:1 extract ratio, 15% psoralen content, and 98% high-purity psoralen isolate—delivering flexibility for diverse end-use applications.
This monograph provides a detailed overview of the botanical source, active constituents, manufacturing process, physicochemical characteristics, functional applications, and supply chain capabilities associated with Psoralea Corylifolia Extract, equipping procurement professionals and R&D teams with the technical information needed for informed sourcing decisions.
Botanical Source & Raw Material Origin
| Attribute | Details |
|---|---|
| Botanical Name | Psoralea Corylifolia Linn. |
| Common Names | Babchi, Buguzhi, Bakuchi |
| Plant Family | Fabaceae (Leguminosae) |
| Plant Part Used | Dried mature seeds |
| CAS Number | 10309-37-2 |
| Harvest Region | Cultivated primarily in China, India, and select regions of Southeast Asia |
The seeds of Psoralea Corylifolia are harvested at full maturity, typically in autumn, when the active furanocoumarin concentration reaches its peak. Careful sourcing of raw material is critical: only seeds meeting established agronomic and phytochemical benchmarks are accepted into the production pipeline. The Extract Factory works with established cultivation partners to ensure traceability from field to finished powder, reducing variability and supporting batch-to-batch consistency.
Active Constituents & Phytochemical Profile
Psoralea Corylifolia Extract contains a complex array of naturally occurring bioactive compounds. The primary pharmacologically relevant constituents include:
- Furanocoumarins: Psoralen, isopsoralen (angelicin), and their methylated derivatives (e.g., methoxsalen-type compounds). These are the core active markers and the basis for standardization.
- Flavonoids: Including psoralone, methyl psoralone, isopsoralone, and various flavonoid glycosides, which contribute to the antioxidant profile of the extract.
- Volatile Oil: Approximately 20% of the seed composition by weight, containing terpenoid fractions.
- Other Components: Organic acids, alkaloids, a methyl glycoside, alkali-soluble resins, non-volatile terpenoid oils, saponins, and fixed fatty oils.
The flower of the plant additionally yields fatty oils, sterols, and alkaloids, though these are not typically part of the seed-based extract described here.
This rich phytochemical matrix makes Psoralea Corylifolia Extract a versatile ingredient for formulations targeting oxidative stress modulation, musculoskeletal support, dermatological care, and traditional wellness protocols.

Extraction & Manufacturing Process
The production of Psoralea Corylifolia Extract follows a controlled, multi-stage workflow designed to maximize yield while preserving the integrity of thermolabile compounds:
- Raw Material Selection & Pre-treatment: Dried seeds are cleaned, sorted, and milled to an optimal particle size to enhance solvent penetration.
- Extraction: The seed material undergoes solvent extraction—typically using ethanol or ethanol-water systems—under controlled temperature and time parameters to selectively dissolve furanocoumarins and flavonoids.
- Concentration: The crude extract is concentrated under reduced pressure (vacuum evaporation) to remove bulk solvent and enrich the active fraction.
- Drying: The concentrated extract is dried using spray drying or vacuum drying technology to produce a fine, free-flowing powder.
- Crushing & Sieving: The dried material is milled and sieved to achieve uniform particle size distribution.
- Packaging: Product is packed in moisture-barrier, light-protective containers under inert atmosphere where applicable.
- Quality Inspection: Every batch undergoes analytical testing (HPLC for psoralen/isopsoralen content, microbial limits, heavy metals, residual solvents, and moisture).
- Storage: Finished product is stored in a cool, dry, light-protected warehouse pending shipment.
This end-to-end process is managed under ISO 9001 quality management principles, ensuring that each lot of Psoralea Corylifolia Extract meets predefined specification limits before release.
Physicochemical Properties & Stability
| Property | Description |
|---|---|
| Physical Form | Fine powder |
| Color | Brown to off-white/white (grade-dependent) |
| Solubility Profile | Ethanol: soluble · Chloroform: soluble · Water: slightly soluble · Ether: slightly soluble · Petroleum ether: slightly soluble |
| Recommended Storage | Cool, dry environment; protect from light and high temperature; ideally below 25 °C in sealed containers |
| Shelf Life | Typically 24 months when stored as directed (verify per batch CoA) |
Formulators should note that furanocoumarins are sensitive to UV light and prolonged heat exposure. Incorporation into final products should account for these stability considerations—particularly for liquid formulations and transparent packaging.

Practical Guidance for Formulators & Procurement Teams
When incorporating Psoralea Corylifolia Extract into your product line, consider the following best practices:
- Solubility Management: For aqueous-based supplements, co-solvent systems (e.g., ethanol-water or glycerin-based) may be needed to achieve adequate dispersion of the furanocoumarin fraction.
- Dosage Calibration: The appropriate inclusion level depends on the target psoralen/isopsoralen dose, the specification grade selected, and the regulatory framework of the destination market. Consult with our technical team for guidance.
- Stability in Final Product: Store finished products away from direct sunlight and excessive heat. Consider opaque or UV-protective packaging for light-sensitive formulations.
