Sphingolipids and glycerolipids. I. Chemical structures and ionophoretic activities of soya-cerebrosides I and II from soybean.
Two glycosphingolipids named soya-cerebrosides I and II were isolated from soybean, the seeds of Glycine max Merrill (Leguminosae), and their chemical structures have been elucidated on the basis ofExpand
Indonesian medicinal plants. XXV. Cancer cell invasion inhibitory effects of chemical constituents in the parasitic plant Scurrula atropurpurea (Loranthaceae).
It was found that the alkynic fatty acid octadeca-8,10,12-triynoic acid exhibits a more potent inhibitory effect on cancer cell invasion in vitro than flavanes. Expand
Transformation of Cinchona alkaloids into 1-N-oxide derivatives by endophytic Xylaria sp isolated from Cinchona pubescens.
The microbial transformation of four Cinchona alkaloids (quinine, quinidine, cinchonidine, and cinchonine) by endophytic fungi isolated from Cinchona pubescens was investigated. The endophyticExpand
Indonesian Medicinal Plants. XII. Four Isomaric Lignan-Glucosides from the Bark of Aegle marmelos (Rutaceae)
From the bark of Aegle marmelos CORREA (Rutaceae), an Indonesian medicinal plant, two new lignan-glucosides, (-)-lyoniresinol 2α-O-β-glucopyranoside (3) and (-)-4-epi-lyoniresinolExpand
Bisanthraquinone metabolites produced by the endophytic fungus Diaporthe sp.
Two bisanthraquinones named (+)-epicytoskyrin (1) and (+)-1,1'-bislunatin (2) were produced by the endophytic fungus from a tea plant, which is a species closely related to Diaporthe phaseolorumExpand
Indonesian medicinal plants. XXIII. Chemical structures of two new migrated pimarane-type diterpenes, neoorthosiphols A and B, and suppressive effects on rat thoracic aorta of chemical constituents
Two novel migrated pimarane-type diterpenes named neoorthosiphols A (1) and B (2) were isolated from the water decoction of the leaves of Orthosiphon aristatus (Lamiaceae), which has been prescribedExpand
Antihypertensive actions of methylripariochromene A from Orthosiphon aristatus, an Indonesian traditional medicinal plant.
It is presumed that the traditional use of this plant in the therapy of hypertension may be partially supported by these actions related to antihypertensive activity with MRC, i.e. vasodilating action, a decrease in cardiac output and diuretic action. Expand
Indonesian Medicinal Plants. XX. Chemical Structures of Eleuthosides A, B, and C, Three New Aromatic Glucosides from the Bulbs of Eleutherine palmifolia (Iridaceae)
Three new aromatic glucosides named eleuthosides A (5), B (6), and C (7), have been isolated from the bulbs of Eleutherine palmifolia (Iridaceae), an Indonesian medicinal plant. Their chemicalExpand
Search for pharmacochemical leads from tropical rainforest plants *
Three Indonesian medicinal plants were investigated to elucidate their biologically active constituents. From the leaves of Scurrula fusca (Loranthaceae), a parasitic plant, was isolated a mixtureExpand
