Best Practices for Storing Cortex Periplocae Extract

• Keep in an Airtight Container

  Air exposure leads to oxidation, which can degrade key active constituents like periplocin and periplogenin. To prevent this, always store the extract in a tightly sealed container. If transferred from the original packaging, use glass or high-density polyethylene (HDPE) containers with secure screw-top lids. Ensure the container is completely dry before use to avoid moisture contamination.

• Store in a Cool, Dry Place

  Heat and humidity accelerate chemical breakdown and promote microbial growth. Ideal storage conditions are below 25°C (77°F) and in low-humidity environments. Avoid placing the extract in kitchens near stoves, in bathrooms, or in vehicles where temperatures fluctuate. A dedicated cabinet away from appliances is ideal for long-term stability.

• Refrigeration for Liquid Extracts

  Liquid formulations, especially alcohol-based tinctures or water-soluble extracts, benefit significantly from refrigeration. Keep them between 2°C to 8°C (36°F to 46°F) to slow microbial growth and preserve potency. Refrigeration is particularly crucial for standardized extracts, suspensions, or those mixed with glycerin or other solvents. Always ensure the cap is tightly sealed to prevent condensation and cross-contamination.

  Note: Some extracts may form sediment or cloudiness when chilled—this is typically normal and does not indicate spoilage. Shake gently before use if applicable.

• Avoid Exposure to Light

  UV and visible light can photo-degrade sensitive compounds in herbal extracts. Use amber glass bottles or opaque containers that block light transmission. If the extract comes in a clear container, store it inside a dark drawer or wrap it in aluminum foil for added protection. This is especially important for extracts high in flavonoids and phenolic compounds, which are prone to photodegradation.

• Label and Date the Container

  Proper labeling helps track freshness and usage. Clearly mark the container with the contents, date of storage, and expiration date (if known). Most properly stored herbal extracts remain effective for 1–2 years, though liquid forms may have shorter shelf lives (6–12 months) without preservatives. For homemade or repackaged extracts, assume a conservative 1-year shelf life unless stability testing is performed.

Storage Factor	Recommended Condition	Risks of Improper Storage	Best Container Types
Temperature	2°C–8°C (refrigerated, liquid); ≤25°C (dry, solid)	Degradation of glycosides, microbial contamination	Glass dropper bottles, HDPE jars
Humidity	Below 60% RH	Caking, mold growth, hydrolysis of compounds	Airtight containers with desiccant packs
Light Exposure	Minimal to none (use dark storage)	Photo-oxidation, loss of flavonoids	Amber glass, opaque plastic
Air Exposure	Sealed environment	Oxidation, reduced potency	Vacuum-sealed or nitrogen-flushed bottles
Labeling	Clear name, date, and concentration	Misidentification, expired use	Water-resistant labels with ink

Expert Tip: For long-term storage of powdered extracts, consider adding a food-safe desiccant packet to the container to absorb residual moisture. Also, minimize headspace in the container to reduce oxygen exposure—this simple step can significantly extend shelf life.

Additional Storage Recommendations

• Do not store near strong-smelling substances (e.g., cleaning products, spices), as herbal extracts can absorb odors.
• Use clean, dry utensils when handling powdered extracts to avoid introducing moisture or contaminants.
• Inspect the extract periodically for changes in color, odor, or texture—these may indicate degradation or spoilage.
