INTRODUCTION Guttiferae (Clusiaceae) is a family of mainly tropical plants that comprises about 40 genera and 1200 species most of which are woody. The plants of the family are generally characterized by the presence of latex in most of their tissue 1. Phytochemical investigations of C. rosea 2, C. nemorosa 3, and C. grandiflora 4 have revealed the presence of polyisoprenylated benzophenones in...

Extracts from Hypericum perforatum (St. John’s wort; Clusiaceae) are widely used for the treatment of mild to moderate depression. Four classes of constituents – hyperforins, hypericins, flavonoids, and xanthones – appear to contribute to the antidepressant activity. Interestingly, all four classes of secondary metabolites involve polyketide derivatives. Key reactions of their biosyntheses are ...

A literature compilation was done to gather information about Cecidomyiidae galls on Clusiaceae in Brazil. Botanical names were verified the site “Flora do Brasil” as well data plant distribution and origin. Two herbaria visited order examine galled specimens of retrieve new locality records. Thirteen gall morphotypes have been recorded three genera (Clusia, Garcinia, Tovomita) eight species. C...

Garcinia schomburgkiana, locally known in Thailand as an edible fruit “Ma-dan”, is a plant species of the Clusiaceae family which has been reported as sources of a variety of compounds with biological activities. In the phytochemical studies of Ma-dan, four xanthones were, for the very first time, isolated from the branch acetone extract of G. schomburgkiana. Their structures were determined th...
