There is provided a plant growth inhibiting and antifungal extract prepared from the leaves and/or vines of plants of the genera Vaccinium and Myrica. There is also provided a method for the preparation of the above-said biologically active extract.

Plant growth inhibiting and antifungal extract prepared from the vegetative parts of plants of the genera vaccinium and myrica

The subject invention provides a myricanol compound that is in predominant form of (+)-.alpha.R,11S-myricanol as compared to (-)-.alpha.S,11R-myricanol. In one embodiment, the (+)-.alpha.R,11S-myricanol is isolated from Myrica cerifera, and is in about 86% enantiomeric excess of (-)-.alpha.S,11R-myricanol. The subject invention also pertains to therapeutic compositions and methods for treatment of neurodegenerative diseases, in particular, neurodegenerative diseases associated with abnormal accumulation of protein tau. Specifically exemplified herein is the therapeutic use of myricanol and myricanone isolated from root barks of Myrica species. Also provided are methods for preparing extracts of the subject invention from Myrica species.
