Improving effects of the extracts from Eugenia uniflora on hyperglycemia and hypertriglyceridemia in mice.
The inhibition of the increase in plasma glucose level by NP-3, 4, 5 and 6 in the oral sucrose tolerance test and the inhibition of a rise in plasma triglycerides byNP-3 and 4 in the Oral corn oil tolerance test were apparently due to the inhibited of the decomposition of carbohydrates and fats in the intestine, respectively.

Cancer chemopreventive effects of a Brazilian folk medicine, Juca, on in vivo two-stage skin carcinogenesis.
Gallic acid (1) and methyl gallate (2) were isolated from Juca, a Brazilian folk medicine, fruits of Caesalpinia ferrea MART (Leguminosae), decreased significantly the average number of papillomasExpand
Inhibition of lipopolysaccharide-induced pro-inflammatory cytokine expression via suppression of nuclear factor-kappaB activation by Mallotus japonicus phloroglucinol derivatives.
It is concluded that these phloroglucinol derivatives inhibit pro-inflammatory cytokine production and mRNA expression via suppression of NF-kappaB activation in activated macrophages. Expand
Polygoacetophenoside, A New Acetophenone Glucoside from Polygonum multiflorum1.
The structure of the new glucoside was deduced to be 2,3,4,6-tetrahy-droxyacetophenone 3- O-beta- D-glucoside by its chemical and spectral data. Expand
Three new lanostanoids from Ganoderma lucidum.
Three new lanostanoids--ganodermenonol (1), ganodermadiol (2), and ganodermatriol (3)--were isolated from the MeOH extract of Ganoderma lucidum, together with ergosterol and its peroxide. Expand
Anti-inflammatory constituents of topically applied crude drugs. II. Constituents and anti-inflammatory effect of Cryptomeria japonica D. Don.

Homonojirimycin analogues and their glucosides from Lobelia sessilifolia and Adenophora spp. (Campanulaceae).
A isolate from the 50% methanol extract of the whole plant of Lobelia sessilifolia (Campanulaceae), which was found to potently inhibit rice alpha-glucosidase, yielded new homonojirimycin derivatives, which are a very specific and potent inhibitor of coffee bean alpha-galactosidases. Expand
Cytotoxic and antiherpetic activity of phloroglucinol derivatives from Mallotus japonicus (Euphorbiaceae).
The phloroglucinol derivatives isolated from Mallotus japonicus Muell. Arg. (Euphorbiaceae) and their derivatives were evaluated for their capacity to produce cytotoxicity in HeLa cells and toExpand
