Background: Camellia sinensis is globally cultivated, principally for the leaves which are used as a green tea. Green tea made from C. sinensis leaves contains various physiologically active ingredients and is used for health and beauty purposes; however, most parts of the plant are discarded. In this experiment the physiological activity of each part of the C. sinensis was analyzed to confirm its potential for use as a cosmetic raw material.
Methods and Results: Leaves, flowers, roots, branches, and seeds were extracted with 70% ethyl alcohol. Experiments were performed to measure, tyrosinase inhibitory activity, elastase inhibitory activity, antibacterial activity, and cell viability upon ultraviolet B (UVB)-induced cell damage. Tyrosinase inhibitory activity was high in leaves, flowers, and roots, and elastase inhibitory activity showed high inhibition rates in roots, leaves, and branches. Antibacterial activity against Propionibacterium acnes was highest in leaves and roots, followed by branches and flowers, with no antibacterial activity found in seeds. In terms of the protective effect from UVB irradiation induced damage, the experimental group treated with the seed extract in HaCaT cells showed a high survival rate. In Detroit cells, an increased survival rate was observed in most of the experimental groups treated with the extracts, particularly those treated with the seed and flower extracts.
Conclusions: Experiment results suggest various parts of the C. sinensis, could be used as raw materials for cosmetics.
