Rosemary Carnosic Acid

PRODUCT INTRODUCTION

Plant Source

Rosemary, Latin name: Rosmarinus officinalis.

Rosemary laef is a labiatae shrub that loves warm climates and is native to Europe and the Mediterranean coast of northern Africa. Rosemary shrubs are 2 meters high, the stems and root branches are cylindrical, the cortex is dark gray, irregularly split, and peeled off in blocks, and the young branches are quadrangular, densely covered with white star-shaped fine hairs.

Rosemary leaves are often clustered on the branches, with very short stalks or sessile, linear leaves, 1-2.5 cm long, 1-2 mm wide, shiny on the top, almost glabrous, covered with white star-shaped tomentose below cover.

Introduction Of Rosemary Extract Powder

What Is Rosemary Leaf Powder?

Rosemary Carnosic Acid, the main component is carnosic acid, the powder is brownish yellow, easily soluble in oil and organic solvents such as ethanol, ethyl acetate, acetone, chloroform, and insoluble in water. Carnosic acid powder can mainly treat hematological malignancy, cardiovascular disease, anti-tumour, inhibit HIV infection, treat intestinal diseases, prevent Alzheimer's disease, heart disease, and hypertension, etc. It is one of the main components of clinical medicine . At the same time, rosemary extracts are used in cosmetics, perfumes, soaps, air fresheners, insect repellents, animal feed, meat products, flavors and other fields.

Rosemary Leaf Powder Benefits

1. Rosemary extract carnosic acid has a strong inhibitory effect on Staphylococcus aureus, Escherichia coli and virus bacteria, and is mainly used as a food preservative;
2. Carnosic acid extract is fat-soluble, which can reduce lipid peroxidation in the liver, regulate low-density lipoprotein, and prevent cardiovascular diseases;
3. Carnosic acid powder can treat arthritis, periodontitis, sore throat, etc.;
4. Rosemary leaf extract can effectively regulate fat absorption, help reduce weight, and achieve weight loss;
5. Rosemary extract powder can prevent Alzheimer's disease, regulate the nerve center, and promote the growth of nerve factors;
6. Rosemary Carnosic Acidcan prevent the growth of senile macula, protect the retina, prevent female macula, whiten and moisturize, treat skin inflammation, and delay skin aging.

Rosemary Carnosic Acid Detection Method

    The content of rosemary carnosic acid and carnosol was determined by RP-HPLC method. With the increase of carnosic acid content, the scavenging rate of lipid free radicals also increased, and the correlation coefficient between the two reached 0.8614. fairly positive correlation. However, the clearance rate did not have any correlation with the content of carnosol.
Five kinds of organic solvents with increasing lipophilicity were selected for detection: methanol, ethanol, acetone, petroleum ether and hexane, and rosemary was extracted respectively by water bath reflux method to obtain different extracts. The determination results showed that the content of carnosol in different solvent extracts had little difference, but the content of carnosic acid had a large difference. This shows that the extraction of carnosic acid cannot use solvents with too strong or too weak polarity, because carnosic acid is degraded during the extraction process using a strong polar solvent, and the solubility of carnosic acid is too weak for solvent polarity. The extracted ingredients are not good. It is necessary to add an entrainer in supercritical fluid extraction because the solubility of CO2 is similar to that of hexane, and the solubility to carnosic acid is low. After adding 95% ethanol, the content of carnosic acid can be increased. If acetone is used as an entrainer, the effect will be lower. than hexane. For the extraction of carnosic acid, you can use a more polar one first, and then use a less polar one, so as to avoid the problem of poor content.

Analysis Method Of Rosemary Extract

1,HPLC
High-performance liquid chromatography is mainly applied to the quantitative (external standard method) analysis of rosemary extract. The evaluation parameters include reproducibility, recovery rate, stability and relative standard error (RSD) of precision, so as to determine Analyze the reproducibility, reliability, stability and precision of the results, and evaluate whether the linear correlation (R2) of the external standard method standard curve is within a reasonable range. According to existing research reports, it is generally believed that when the RSD of the reproducibility of the measured experimental results is less than 1%, it indicates that the reproducibility is good, and when the RSD of the recovery rate is less than 2%, it is more reliable; when the RSD of the measured peak area is less than 3 %, it shows that the stability is good, and when the RSD of the measurement precision is less than 3.5%, it shows that the precision is good. The range of the standard line of the external standard method is based on the actual content range of the rosemary extract to be detected, and then the accuracy of the standard curve is determined by examining the linear correlation.

2,Other detection methods
Other methods for detection of rosemary extract mainly include HNMR, CNMR, IR, MS, GC, CE and several detection methods combined. Different detection methods have their own analysis characteristics.
