Our Natural Rosemary Extract Powder is a high-purity concentrate from Rosmarinus officinalis(Yunnan Dali highlands, China’s premier rosemary-growing region), processed via low-temperature ethanol extraction (40°C) and macroporous resin purification to isolate active compounds. Sourced from hand-harvested mature leaves (peak carnosic acid stage), it is standardized for carnosic acid (25%-60% HPLC) and rosmarinic acid (15%+ HPLC), with zero additives and high-altitude cultivation authenticity (1800-2200m for optimal antioxidant density). The powder is 80-mesh fine-ground and ideal for food preservation, functional ingredients, and natural antioxidant applications.
- Carnosic Acid Leadership: 25%-60% HPLC-verified (industry’s widest range), with 40% spec offering 2x higher potency than average extracts (stable radical scavenging).
- Precision Purification: Macroporous resin tech isolates carnosic acid from polyphenols (purity >95%), avoiding bitter aftertaste.
- Gentle Processing: Low-temperature extraction + spray drying retains 92% of actives (vs. 70% in heat extraction).
- Global Compliance: Halal/Kosher certified, Non-GMO, meets FDA/EFSA food additive standards and EU Novel Food regulations.
