Testing Method:

● Principle: 

The effective substances in rosemary will be dissolved out using ethanol as the extraction solvent. Ethanol is chosen for its safety, effectiveness, and economy. For rosemary extraction, it is recommended to use ethanol as the organic solvent, with a liquid to material ratio of 10:1, and within a 2-hour extraction time. The concentration of ethanol should be controlled to avoid dissolving non-polar substances in rosemary, such as chlorophyll. To increase yield, the method can be combined with microwave shaking or other techniques.

 

● Influencing factors: 

Ethanol concentration, extraction temperature, material-to-liquid ratio, extraction time, and number of extractions, among others.

 

● Advantages: 

The solvent method is effective, efficient, and cost-effective. It is suitable for industrial application and yields high and stable extraction rates. For example, the extraction rate for syringic acid from herbs is high, and the extraction rate of ursolic acid from rosemary is 92.38%, with high purity. Additionally, various antioxidant components in rosemary can be extracted simultaneously. The method is user-friendly, eco-friendly, and safe.

 

Active Substance

● Phenolic Acids

Natural Rosemary Extract contains several phenolic acid compounds, including rosmarinic acid, rosmanol, carnosic acid, carnosol, caffeic acid, and ursolic acid. These compounds feature multiple phenolic hydroxyl substitutions, making them sensitive to environmental factors and prone to chemical changes. They are often added to drugs with anti-inflammatory and antibacterial effects to enhance their biological activity.

 

● Flavonoids

Flavonoids were the first plant extract components to be studied, and more than 40 kinds have been extracted from rosemary so far. Rosemary is rich in flavonoids, with small amounts of flavonols and flavanones. Examples include rutin, quercetin, thistaxanthin, naringin, luteolin, genkwain, hesperetin, celery and its glycoside derivatives.

 

● Volatile Essential Oil Components

Rosemary essential oil typically contains complex and volatile monoterpenes and sesquiterpenes. Its composition varies depending on the source. Rosemary's natural essential oil components play a critical role in the spice crop's physiological functions, such as antioxidant and antibacterial activities. Common ones include 1,8-cineole, α-pinene, camphor, camphene, β-pinene, among others. These compounds offer functions like relieving cough, reducing phlegm, reducing inflammation and diuresis. They also have protective effects on the cardiovascular and cerebrovascular.

 

● Terpenes

Terpenes are the most abundant and complex components of rosemary, comprising monoterpenes, sesquiterpenes, diterpenes and triterpenes. Monoterpenes include 1,8-cineole, camphor, α-pinene, camphene, β-pinene, myrcene, etc. Diterpenoids are the main polyphenols in rosemary. Examples include carnosic acid, carnosol, rosmanol and their derivatives. Triterpenoids consist of triterpene acid compounds, mostly including squalene, ursolic acid, oleanolic acid, betulin, betulinic acid, etc.

 

Market:

Currently, natural rosemary extract has gained popularity among natural and environmentally conscious consumers due to its superior antioxidant properties, pure natural composition, and lack of harmful effects on the human body. Rosemary's antioxidant properties remain effective even at high temperatures up to 240℃ and does not affect the appearance of the final product's color, which provides many advantages over traditional synthetic antioxidants. As consumer health awareness continues to rise, natural antioxidant products will inevitably become more prevalent in the market.
