The stability of lavender, lemon balm, mint, sage, and thyme teas was investigated using in‐vitro simulation of the digestive system. Kinetics of changes in the total polyphenolic content (TPC) and the antioxidant activity during the in‐vitro trials were also evaluated. Results showed that TPC of mint teas decreases the fastest. Mathematical models for prediction of the TPC and the antioxidant activity of prepared teas based on UV–VIS and NIR spectra collected before, during, and after simulation showed that the best prediction was obtained for the wavelength ranges from 410 to 900 nm, 904 to 928 nm, and 1,399 to 1699 nm. It was concluded that the NIR can be used for calibration, validation, and classification of teas prepared from Lamiaceae plants.

唇形科家庭凉茶中生物活性物质的体外消化：动力学和PLS建模研究。
使用消化系统的体外模拟研究了薰衣草，柠檬香脂，薄荷，鼠尾草和百里香茶的稳定性。还评估了体外试验中总多酚含量（TPC）和抗氧化活性的变化动力学。结果表明，薄荷茶的TPC下降最快。基于模拟之前，之中和之后收集的UV-VIS和NIR光谱预测茶的TPC和抗氧化活性的数学模型表明，对于410至900 nm，904至928的波长范围，可获得最佳的预测1399至1699 nm。结论是，NIR可用于校准，验证和分类唇形科植物茶。
