Skin-protection composition containing Dendrobium-based ingredients
The present invention relates to a skin-protection composition that comprises stilbenoid(s) and/or stilbenoid-containing extract(s) obtained from Dendrobium plants, such as Dendrobium officinale and Dendrobium nobile for the management of melanogenesis, skin-darkening and skin-aging. More particularly, it relates to the usage of Dendrobium ingredients and stilbenoids to reduce the formation of melanin in melanocytes. It also relates to the usage of Dendrobium ingredients and stilbenoids to reduce the generation of reactive oxygen species and oxidative free radicals. This invention relates to the use Dendrobium-derived extracts or ingredients or stilbenoids in the formulation of skin-protection, skin-whitening and/or anti-skin aging products.

Method of using of dihydro-resveratrol or its stilbenoid derivatives and/or chemical variants as antimicrobial agents
The present invention relates to a composition for preventing or reducing microbial growth, particularly the growth of dermatophytic fungi, and/or aciduric and acidogenic gram-positive bacteria. More particularly, it relates to the use of trans-3,5,4-trihydroxybibenzyl, also known as dihydro-resveratrol, or its dihydrostilbene derivatives and/or chemical variants as an anti-microbial agent. The present invention further relates to the management of dermatophytosis often caused by dermatophytic fungi and the management of dental caries often mediated by aciduric and acidogenic gram-positive Streptococci. The present invention therefore has applications in preventing, alleviating and/or treating dermatophytosis and dental caries.
SYNTHESIS OF CANNABIDIOL AND ANALOGS THEREOF, AND RELATED COMPOUNDS, FORMULATIONS, AND METHODS OF USE
Methods are provided for the synthesis of olivetol, olivetol analogs, cannabidiol (CBD), CBD analogs, and other cannabinoids; one method employs phloroglucinol or a phloroglucinol analog as a starting material. The syntheses are stereospecific, efficient, selective, and cost-effective, with little or no potential for generation of THC ((?)-trans-?.sup.9-tetrahydro-cannabinol) or any other psychoactive side product. Telescoped syntheses are also provided, as are new cannabinoids, pharmaceutical formulations, and methods of use.
