For example, if there are contaminants from the plant source that are not removed during purification, they may have unknown toxic effects on the body.
• Food and Dietary Supplements: In the food and supplement industry, purity is important for consumer confidence. Consumers expect the products they consume to be pure and free from harmful substances. A pure rutin product is also more likely to have consistent quality, which is crucial for accurate labeling and meeting regulatory requirements.
• Cosmetic Formulations: In cosmetics, purity of rutin is necessary to prevent skin irritation or allergic reactions. Impure rutin may contain substances that can cause adverse skin reactions, especially for those with sensitive skin. Moreover, high - purity rutin can ensure the stability of cosmetic formulations, as impurities may interact with other ingredients and cause degradation or instability.

5. Impact of Potency and Purity on Rutin's Performance

The potency and purity of rutin are closely related to its performance in various applications.

• Biological Activity: High - potency rutin with high purity is more likely to exhibit strong biological activity. For example, in antioxidant activity, pure and potent rutin can effectively scavenge free radicals, protecting cells from oxidative damage. In contrast, low - potency or impure rutin may not be as effective in this regard.
• Stability: Purity affects the stability of rutin. A pure rutin sample is less likely to interact with other substances and degrade over time. High - potency rutin also tends to be more stable in appropriate storage conditions, as its chemical structure is more intact and can better resist environmental factors such as temperature and humidity.
• Compatibility: In formulations, both potency and purity play a role in compatibility with other ingredients. A pure and potent rutin can be more easily incorporated into pharmaceutical, food, or cosmetic formulations without causing unwanted interactions or reducing the effectiveness of other ingredients.

6. Safety Considerations Related to Potency and Purity

• Toxicity: Impurities in rutin can potentially increase its toxicity. In the pharmaceutical field, if the purification process is not thorough, there may be residual solvents or other contaminants that can be harmful to the body. High - purity rutin, on the other hand, reduces the risk of such toxicity. Regarding potency, an overly potent rutin preparation without proper safety assessment may also pose risks. For example, if it has an extremely strong biological effect, it may disrupt normal physiological processes in the body.
• Allergenicity: Purity is crucial in reducing the risk of allergenicity. If rutin contains impurities from the plant source, such as proteins or other allergens, it may cause allergic reactions in sensitive individuals. Ensuring high purity can minimize this risk. While potency itself may not directly relate to allergenicity, a more potent rutin product may be more likely to cause adverse reactions if it contains impurities.
