Alkaloids from the seeds of Peganum harmala showing antiplasmodial and vasorelaxant activities
Quinazoline alkaloid, vasicinone, showed a vasorelaxant activity against phenylephrine-induced contraction of isolated rat aorta and a moderate in vitro antiplasmodial activity against Plasmodium falciparum. Expand
Cytotoxic diterpenes from the rhizomes of Hedychium coronarium.
Structures and cytotoxic activity relationship of casearins, new clerodane diterpenes from Casearia sylvestris Sw.
Casearins G-R, new cytotoxic clerodane diterpenes have been isolated from the leaves of Casearia sylvestris Sw. (Flacourtiaceae). Their structures have been elucidated by spectroscopic methods andExpand
Cytotoxic aromatic triterpenes from Maytenus ilicifolia and Maytenus chuchuhuasca.
The isolation and structure elucidation of four cytotoxic aromatic triterpenes [1-4] along with three known quinoid triterpenes [5-7] from the South American medicinal plants Maytenus ilicifolia andExpand
Cr(VI) reduction from contaminated soils by Aspergillus sp. N2 and Penicillium sp. N3 isolated from chromium deposits.
Aspergillus sp. N2 and Penicillium sp. N3 are chromate-resistant filamentous fungi that were isolated from Cr(VI) contaminated soil based on their ability to decrease hexavalent chromium levels inExpand
Studies on the constituents from the fruits of Phaleria macrocarpa
From the fruits of Phaleria macrocarpa, icariside C3 (1), phalerin (2), and mangiferin (3) were isolated and their structures were identified on the basis of spectroscopic data. Icariside C3 (1)Expand
Single-Cell Protein Production by the Acid-Tolerant Fungus Scytalidium acidophilum from Acid Hydrolysates of Waste Paper
The bioconversion of waste paper to single-cell protein at pH <1 by Scytalidium acidophilum is described, and the chemical constituents and the essential amino acids of the fungal cells were similar to those of other fungi. Expand
New antitumor principles, casearins A-F, for Casearia sylvestris Sw. (Flacourtiaceae).
New antitumor clerodane diterpenes, named casearins A-F, have been isolated from the leaves of Casearia sylvestris Sw. (Flacourtiaceae). These structures have been completely elucidated by twoExpand
Diarylheptanoids from the Rhizomes of Curcuma xanthorrhiza and Alpinia officinarum
Five diarylheptanoids including two new compounds were isolated from the rhizomes of Curcuma xanthorrhiza (Zingiberaceae). The structures of the new compounds were determined to be octahydrocurcuminExpand
Diterpenes from the rhizomes of Alpinia formosana
A new labdane-type diterpene, (E)-labda-8(17),12-diene-15-ol-16-al was isolated from the rhizomes of Alpinia formosana together with two known sesquiterpenes and three known phenolic compounds. Expand
