Overview
Drosera Extract is obtained from the carnivorous sundew plant (Drosera spp.), native to wetlands worldwide. Traditionally used in European folk medicine for respiratory ailments, modern research highlights its bioactive compounds like plumbagin, which exhibit antimicrobial and anti-inflammatory effects. The extract is produced via solvent extraction (ethanol/water) of dried leaves, followed by filtration and concentration. Its applications span pharmaceuticals, particularly in cough remedies due to its mucolytic properties, and cosmetics for its skin-soothing benefits.
Physical and Chemical Properties
Drosera Extract is a complex mixture containing naphthoquinones (e.g., plumbagin), flavonoids, and proteolytic enzymes like droserone. Its brownish-yellow color and solubility in polar solvents make it versatile for formulations. Key chemical markers include plumbagin (typically 0.5–5% by HPLC), which contributes to its therapeutic effects. The extract is pH-sensitive (stable at 4–6) and degrades under prolonged UV exposure, necessitating opaque packaging.
Main Applications
In pharmaceuticals, Drosera Extract is a key ingredient in antitussive syrups and lozenges, leveraging its ability to break down mucus proteins. Clinical studies support its use for mild bronchitis. The cosmetic industry values it for acne treatments and anti-aging serums, where plumbagin’s antimicrobial action combats Propionibacterium acnes. It’s also emerging in herbal supplements for immune support, often combined with echinacea or propolis.
Safety and Storage
While generally recognized as safe (GRAS) for topical and oral use in diluted forms, undiluted extract may cause dermatitis. Always conduct patch testing in cosmetic formulations. Storage requires refrigeration (2–8°C) in amber glass or HDPE containers to prevent oxidation. Shelf life is approximately 24 months under ideal conditions, though potency declines after 18 months.
B2B Procurement Guide
When sourcing Drosera Extract, prioritize suppliers providing Certificate of Analysis (COA) with HPLC quantification of plumbagin. Organic certification (e.g., USDA/EU) is advisable for cosmetic applications. Bulk pricing tiers apply: orders above 50 kg often attract 10–15% discounts. Lead times vary by season (harvest occurs in late summer), so plan purchases accordingly. Consider freight options with temperature control for international shipments.
