4.1 Assessing Potency

• Biological Assays: These are often used to measure the biological activity of the Sophora japonica flower extract. For example, antioxidant assays can be conducted to determine the extract's ability to scavenge free radicals. One common method is the DPPH (2, 2 - diphenyl - 1 - picrylhydrazyl) assay. In this assay, the extract is added to a solution of DPPH radicals. If the extract has antioxidant activity, it will react with the DPPH radicals, causing a decrease in the absorbance of the solution, which can be measured spectrophotometrically.
• Cell - based Studies: These studies involve exposing cells to the extract and observing the cellular responses. For example, in anti - inflammatory studies, cells can be stimulated to produce inflammatory markers, and then the extract is added to see if it can reduce the production of these markers. This can help to evaluate the extract's potential anti - inflammatory potency.
• Animal Models: Animal models can also be used to assess the potency of the extract. For example, in studies related to the treatment of arthritis, animals with induced arthritis can be treated with the extract, and the improvement in their joint symptoms can be observed and measured. This provides valuable information on the extract's therapeutic potency in vivo.

4.2 Assessing Purity

• Analytical Chemistry Techniques: High - performance liquid chromatography (HPLC) is a commonly used technique for assessing the purity of Sophora japonica flower extract. HPLC can separate and quantify the different components in the extract, allowing for the identification of the active components and the detection of any impurities. Gas chromatography (GC) can also be used, especially for analyzing volatile components in the extract.
• Spectroscopic Methods: Spectroscopic methods such as ultraviolet - visible (UV - Vis) spectroscopy and infrared (IR) spectroscopy can provide information about the chemical structure of the extract and can be used to detect any abnormal absorption peaks that may indicate the presence of impurities.
• Microbial Testing: Since microbial contamination can also affect the purity of the extract, microbial testing is essential. Tests for bacteria, fungi, and yeast can be carried out to ensure that the extract is free from microbial contamination.
