Abstract: A novel compound isolated from the plant Garcinia paucinervis. The compound's structure is as follows: The compound possesses a potent ability to activate caspase-3 in HeLa-C3 cells within 72 h at a low concentration of 25 ?M. The IC50 on HeLa cells for this compound was measured to be below 10 ?M, indicating a strong HeLa cell growth inhibitory effect.

Abstract: Novel polyisoprenylated benzophenone derivatives isolated from the plant Garcinia paucinervis. Among these new compounds, paucinones A-C (Compounds 1-3) contains an unexpected cyclohexane-spiro-tetrahydrofuran moiety. A 1-methylene-3,3-dimethylcyclohexane group never reported before was found in the structure of paucinone D (Compound 4). Structures of these compounds were elucidated with spectroscopic evidence. The relative stereochemistry of 1-4 was determined by NOESY correlations. These compounds a potent ability to activate caspase-3 in HeLa-C3 cells within 72 hours at a low concentration and significant cytotoxicity against HeLa-C3 cells.

Abstract: A housing comprise a decorative layer including a transparent base, a first conductive coating, an electrically conductive ink layer having a first electrical interface and a second conductive coating having a second electrical interface. The first conductive coating is formed on the base, the electrically conductive ink layer is laminated with and covers the first conductive coating, the second conductive coating is laminated between the electrically conductive ink layer and the outer surface of the substrate, the first electrical interface of the first conductive coating and the second electrical interface of the second conductive coating are electrically connected to a power source for creating an electrical field between the first conductive coating and the second conductive layer to make the electrically conductive ink layer present a pattern.

Abstract: A housing comprises an exterior coating and a substrate. The housing further comprises a first conductive coating, a light emitting coating and a second conductive coating formed between the exterior coating and the substrate. The substrate formed on the second conductive coating by molding. The first and the second conductive coatings include electric contacts. An electronic device using the housing is also described there.

Abstract: Three pairs of C-2 epimeric xanthones isolated from Garcinia hanburyi and method for efficiently separating the xanthone compounds into individual epimers, each of which possesses varying biological effects. The compounds are useful for their anticancer effects, particularly because they are shown to be non-substrates of the multidrug-resistance transporter. Some of the epimers have significant inhibitory effects on cytochrome P450 systems. The xanthone compounds of the present invention are gambogic acid, epigambogic acid, isogambogic acid, isoepigambogic acid, 30-hydroxygambogic acid and 30-hydroxyepigambogic acid.

Abstract: Two novel benzofuran glycosides, named psoralenoide and isopsoralenoide, isolated and purified from the seeds of Psoralea corylifolia. The compounds are useful as therapeutic agents for diseases defined under TCM and as a more accurately means of quality control and assessment for Psoralea corylifolia, an important herbs used in TCM.

Abstract: In accordance with the present invention, novel compositions useful for the treatment of the cytopathogenic effects of an enveloped virus in mammals have been discovered by extraction and purification from the spikes of Prunella vulgaris. In particular, invention compositions comprise a lignin-carbohydrate complex as an active ingredient for inhibition of viral infection in a mammal. In accordance with an embodiment of the present invention, it has been discovered that invention compositions are effective agents for the prophylaxis and therapy in mammals of diseases caused by enveloped viruses, e.g., herpes simplex virus. Methods for producing invention compositions and uses therefor are also provided.
