原花青素（PC）是植物果实、种子、花和皮中的黄酮类化合物，具有强抗氧化性和自由基清除能力。本试剂盒采用硫酸-香草醛法测定原花青素含量：酸性条件下，原花青素A环上的间苯二酚和间苯三酚与香草醛缩合生成500 nm处有特征吸收的有色产物，通过测定该波长下吸光度（其与原花青素含量成正比），即可定量样品中原花青素浓度。
Proanthocyanidins (PC) are flavonoid compounds found in plant fruits, seeds, flowers, and peels, and are known for their strong antioxidant activity and free radical scavenging capacity. This kit employs the sulfuric acid‑vanillin method for the determination of proanthocyanidin content. Under acidic conditions, the resorcinol and phloroglucinol moieties on the A‑ring of proanthocyanidins condense with vanillin to form a colored product that exhibits a characteristic absorption peak at 500 nm. By measuring the absorbance at this wavelength, which is directly proportional to the proanthocyanidin content, the concentration of proanthocyanidins in the sample can be quantitatively determined.
