Four new phloroglucinol derivatives, named garsubellins B similar to E, have been isolated from the wood of Garcinia subelliptica. Their structures have beer elucidated by extensive analysis of spectroscopic data rind comparison with those of previously known garsubellin A. Garsubellins which represent novel polyisoprenylated phloroglucinols having a hydrofuran ring are regarded as chemical components characteristic of the title species. (C) 1998 Elsevier Science Ltd.
