Cryptomeria japonica is one of the most important forest tree species in Japan. To increase the demand for domestic timber, broad uses related to the functional attributes of C. japonica must be developed. Several studies have examined the usefulness of C. japonica in terms of its biological activities, but a comprehensive study subjecting all parts of the C. japonica plant to the same solvent for extraction has not been done. Here, methanol extractions from the leaves, branches, bearing branches, male flowers, female flowers, cones, bark, heartwood, sapwood, pith, rhizomes, roots, and pollen were subjected to several in vitro assays of their biological activities such as antioxidant activity, anti-lipase activity, antibacterial activity and melanin-biosynthesis-inhibition activity. Their total phenolic content was also determined. The methanol extracts from each part of C. japonica except for pollen showed strong activities in the bioactivity assays. Furthermore, the methanol extracts were analyzed by GC/MS. The phytochemical profile varied among extracts from various parts of C. japonica. Our results suggest the great potential of C. japonica for use as a functional ingredient in health-related products.
