Active Ingredients:

The active ingredients are rosmarinic acid powder and its derivatives, such as caffeic acid, chlorogenic acid, and rosmarinic acid hexoside. These compounds possess potent bioactive properties and could be used in various health supplements and pharmaceutical applications.

 

Testing Methods:

● High-performance liquid chromatography (HPLC)

The HPLC method allows the separation and quantification of different components based on their physical and chemical properties, including molecular weight, solubility, and polarity. To use this method, a sample is dissolved in a solvent and then injected into an HPLC system. Then it separates the components in the sample, allowing for accurate quantification of rosmarinic acid.

 

● Spectrophotometry

It is commonly used to determine the concentration of rosmarinic acid in dietary supplements. In this method, a sample is dissolved in a solvent and then exposed to a specific wavelength of light. The amount of light absorbed or transmitted by the sample is then measured, allowing for the calculation of the concentration of rosmarinic acid.

 

● Gas chromatography-mass spectrometry (GC-MS)

 It is a combined technique that involves separating the different components by gas chromatography and identifying them by mass spectrometry. This method allows for the detection of trace amounts of rosmarinic acid in dietary supplements.

 

● Thin-layer chromatography (TLC)

TLC is commonly used to identify the presence of rosmarinic acid in dietary supplements. In this method, a small amount of rosmarinic acid powder is applied to a thin layer of absorbent material such as silica gel or cellulose. The sample is then exposed to a solvent, which allows for the separation of the components. The presence of rosmarinic acid is detected by exposing the TLC plate to a specific reagent or by visual inspection under ultraviolet light.

 

● Nuclear magnetic resonance spectroscopy (NMR)

NMR is commonly used to confirm the identity of rosmarinic acid in dietary supplements. In this method, a sample of rosmarinic acid powder is dissolved in a solvent and then exposed to a strong magnetic field. Different nuclei in the sample absorb energy at different frequencies, providing information about the chemical structure.
