Juglans mandshurica has a high medical value

because its barks

leaves and fruits can be used as medicines. In this study

chemical components of J. mandshurica and bioactivities were reviewed based on the domestic and foreign literatures in the past 20 years. So far

flavones

quinines

polyphenols

terpenoids

volatile oils and other chemical constituents have been isolated from J. mandshurica. According to pharmacological studies

both its crude extracts and specific chemical constituents show good bioactivities

including anti-inflammatory

analgesic

anti-tumor

antioxidant and antiviral effects. Currently

despite some advances in its chemical constituents and pharmacological activities of J. mandshurica

there is still no intensive study on the action mechanism of its effective constituents. Therefore

further studies will be conducive to developing new medicines and making the most use of natural medical resources.
