Preparation of a tea polyphenol nanoliposome system and its physicochemical properties.

Tea polyphenol is rich in green tea with diverse biological activities. However, its application in the food industry is limited due to its instability toward oxygen and light. In this study, the preparation of tea polyphenol liposome by the thin film ultrasonic dispersion method was performed in order to enhance the bioavailability of tea polyphenol.

Optimization of the microwave-assisted extraction conditions of tea polyphenols from green tea.

Green tea, a popular drink with beneficial health properties, is a rich source of polyphenols that have a wealth of physiological activities. The purpose of the present study was to develop a microwave-assisted extraction (MAE) of green tea polyphenols. MAE of tea phenols from green tea was investigated through orthogonal array design.

Extraction and removal of caffeine from green tea by ultrasonic-enhanced supercritical fluid.

Low-caffeine or caffeine-removed tea and its products are widely welcomed on market in recent years. In the present study, we adopt ultrasonic-enhanced supercritical fluid extraction process to remove caffeine from green tea. An orthogonal experiment (L16 (4(5))) was applied to optimize the best removal conditions.

Identification and quality control of Chinese medicine based on the fingerprint techniques.

Traditional Chinese medicine (TCM) contains a large number of herbal medicine and Chinese patent medicine, each of which contains many compounds that may be relevant to the medicine's putative activity. The homonym and synonym are very popular in TCM for its source complex. How to identify species and control the quality of TCM has become urgent, and fingerprint techniques have now been widely used in TCM for these purposes.

Application of targeted drug delivery system in Chinese medicine.

Targeted drug delivery system of traditional Chinese medicine (TCM) refers to those using different carriers to make the effective parts or monomer extracted from TCM or natural medicine into agents which can directly concentrate on the target site. This system is an ideal delivery approach and has became a hot spot in the field of TCM pharmaceutical research since it can improve the pharmacological effects and reduce the adverse reactions. This paper reviews literatures on TCM targeted agents which were published in the past 10 years.
