Aphrodisiac Principles and other Constituents from the Roots of and .

Bioassay-guided fractionation of and root extracts afforded six compounds. Among these, two bioactive compounds ginsenoside Re () and (20)-ginsenoside Rg2 () exhibiting significant relaxation in rabbit corpus cavernosum with EC values of 95.1 and 114.

Chemical Constituents of and Their Anti-Inflammatory Bioactivities.

Seven new anthraquinones with rare 2-isopropyldihydrofuran (-) and 2,2-dimethylpyrano (-) moieties together with thirty-four known compounds were isolated from the extracts of whole plants. Their structures were elucidated and established by various spectroscopic and spectrometric analytical methods. Among these isolates, selected compounds were examined for their anti-inflammatory activity.

Constituents from the Fruiting Bodies of and in Vietnam and Their Anti-Inflammatory Bioactivity.

It is reported that various fungi have been used for medicine and edible foods. The tropical genus is popular and well-known in Vietnam for its health effects and bioactivities. In this study, the fruiting bodies of the edible fungi and were collected in Vietnam.

Bioactive naphthoquinones and triterpenoids from the fruiting bodies of Taiwanofungus salmoneus.

Drug resistance of cancer cells stands for the major problem of the treatment failure for chemotherapy or target therapy. Overexpression of efflux pumps leading to multidrug resistance (MDR) is still an important issue needed to be solved. In the present study, Taiwanofungus salmoneus was selected as the topic and eleven undescribed constituents including four naphthoquinones salmonones A-D (1-4) and seven triterpenoids salmoneatins A-G (5-11), along with one chromanone (12) and two benzenoids (13 and 14) reported from the natural sources for the first time, as well as twenty-one known compounds were characterized.

Antiinflammatory triterpenoids from the fruiting bodies of Fomitopsis pinicola.

Twelve undescribed lanostane-type triterpenes, and twenty-two known triterpenes were isolated and identified from a medicinal bracket fungus Fomitopsis pinicola (Sw.) P. Karst.

Secoiridoids from the Seed of and Their Inhibitory Potential on LPS-Induced Tumor Necrosis Factor and Nitric Oxide Production.

Three new secoiridoid constituents, goncarin A−C (⁻), and a new derivative, goncarin A monoacetate (), along with two known lignins, pinoresinol () and paulownin (), were isolated from the seed of (Baill.) Becc. The structures of the new metabolites were determined on the basis of extensive spectroscopic analysis, particularly mass spectroscopy and 2D NMR (¹H⁻¹H COSY, HMQC, HMBC, and NOESY) spectroscopy.
