transform renewable lignin‐derived alcohols to various functionalized bibenzyl chemicals. This strategy relied on a short deoxygenation coupling pathway with economical molybdenum catalyst. A well‐designed H‐donor experiment was performed to investigate the mechanism of this Mo‐catalyzed process. It was proven that benzyl carbon‐radical was the most possibleintermediate to form the bibenzyl products.

The present invention relates to a polyphenol derivative of the stilbenoid family, namely trans-3,5,4′-trihydroxybibenzyl, also known as dihydro-resveratrol, as a remedial agent. In particular, the present invention presents the usage of dihydro-resveratrol or its derivatives/chemical variants in the manufacture of a medicament for the treatment of tumors or cancers. The dihydrostilbenes can be used in the treatment or delay of progression of a cancer in a patient or used in a pharmaceutical formulation for the aforementioned purposes.
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.

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.
