4. Studies on the chemical composition of some Vietnamese medicinal plants Paederia scandens, Gardenia jasminoides Ellis...(Rubiaceae).
5. Investigation of the biologically active substances from fruit bodies of the inedible mushrooms Daldinia concentrica, Thelephora aurantiotincta, Pulveroboletus ravenelii, Hypoxylon truncatum, Paxillus curtisii, Tyromyces fissilis, Hydnellum caeruleum, Hypoxylon fuscum, H. rubiginosum and Ganoderma species from Japan, Germany and Vietnam.
6. Studying on the chemotaxonomy of Xylariaceae family by using the combination of morphological methods and HPLC profiling.
7. Examination on the biological activities of the isolated compounds from medicinal plants and inedible mushrooms, such as antioxidant, antimicrobial, anti HIV, inhibitory activities of TNF-alpha and nitric oxide production in macrophages stimulated by LPS. In addition, total RNA extraction, follow by RT-PCR and Western analysis of iNOS protein espressed in cells were carried out to find out the mechanism of the inhibitory activity of the isolated compounds.
