Abstract Coussarea macrophylla ( Mart .) Müll.Arg . (Rubiaceae) was collected in Ecuador, and the bark extracted with AcOEt. Chromatographic separation afforded six novel 3,4‐secocycloartane 3,4‐secodammarane triterpenes, named macrocoussaric acids A–F, together known metabolites secaubryenol 3,4‐secodammara‐4(28),20,24‐triene‐3,26‐dioic acid. The structures of new compounds were determined on basis their spectroscopic data. This is first report triterpenes occurring a species....
In addition to the known bioactive triterpene cucurbitacin B (1), two new cucurbitane triterpenoids, namely, leucopaxillones A (3) and (4), exhibiting a oxygenation pattern among cucurbitacins, have been isolated from mushroom Leucopaxillus gentianeus (syn. L. amarus). Cucurbitacin (1) imparts bitter taste flesh of fungus; however, it occurs in fruiting bodies mainly esterified as tasteless fatty acid esters 2a−c. vitro growth inhibitory effects compounds 1−4 on proliferation four different...
Abstract Die Addition der Sulfonylazide an Äthoxyacetylen ergibt α‐Diazo‐ N ‐sulfonyl‐acetimidsäure‐äthylester, eine neue Klasse aliphatischer Diazoverbindungen. Deren Umsetzungen mit konz. Salzsäure, Fumarsäure‐diäthylester, Phenylacetylen, Triphenylphosphin und katalytisch erregtem Wasserstoff werden beschrieben.
In remote villages of Kurdistan-Iraq, such as in those on Safeen Mountain, decoctions, potions, and oils from the local herbal tradition have provided only medicinal remedies for centuries, up to today. A variety diseases are treated with different plant preparations, ranging simple rheumatism diarrhea, skin diseases, highly complicated kidney heart problems. This survey describes, first time, mostly used plants, resulting several interviews healers. The bioactivity some isolated compounds...

This work features the results of an ethnobotanical study on uses medicinal plants by inhabitants region near to Kutukú Scientific Station Universidad Politécnica Salesiana, located in Morona-Santiago province, southeast Ecuador. In surroundings station, one ethnic group, Shuar, has been identified. The survey hereafter reports a total 131 plant species, with 73 different therapeutic uses.
