Insecticidal Activity of <i>Jatropha</i> Extracts Against the Azalea Lace Bug, <i>Stephanitis pyrioides</i> (Hemiptera: Tingidae) Open
We assessed bioactivity of ethanolic extracts from 35 species of Jatropha L. against an ornamental plant pest, the azalea lace bug, Stephanitis pyrioides (Scott). Jatropha extracts were prepared by air-drying stem, root, or whole plant mat…
Furanocoumarin with Phytotoxic Activity from the Leaves of <i>Amyris elemifera</i> (Rutaceae) Open
Bioassay-guided fractionation of the ethyl acetate extract of Amyris elemifera leaves was carried out to identify phytotoxic and antifungal constituents. A novel phytotoxic furanocoumarin 8-(3-methylbut-2-enyloxy)-marmesin acetate (1) and …
CCDC 1821493: Experimental Crystal Structure Determination Open
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available …
Fungicidal Properties of Some Novel Trifluoromethylphenyl Amides Open
Trifluoromethylphenyl amides (TFMPAs) were designed and synthesized as potential pesticides. Thirty‐three structures were evaluated for fungicidal activity against three Colletotrichum species using direct bioautography assays. Active comp…
Bioassay-Guided Isolation and Structure Elucidation of Fungicidal and Herbicidal Compounds from Ambrosia salsola (Asteraceae) Open
The discovery of potent natural and ecofriendly pesticides is one of the focuses of the agrochemical industry, and plant species are a source of many potentially active compounds. We describe the bioassay-guided isolation of antifungal and…
A Phytotoxic and Antifungal Metabolite (Pyrichalasin H) from a Fungus Infecting <i>Brachiaria eruciformis</i> (Signal Grass) Open
Brachiaria eruciformis (sm.) Griseb, locally known as “signal grass”, is a common weed in lawns and turfs in Mississippi, USA. During late spring and early summer months, leaves of B. eruciformis are infected with a fungus causing necrosis…

Phytotoxic Lignans from <i>Artemisia arborescens</i> Open
A systematic bioassay-guided fractionation of methylene chloride extracts of the aerial part of Artemisia arborescens was performed in order to identify its phytotoxic compounds Two lignans were isolated, sesamin and ashantin, that inhibit…
Antifungal and repellent activities of the essential oils from three aromatic herbs from western Himalaya Open
In this investigation we examined the essential oils of three aromatic plants, Zanthoxylum armatum , Juniperus communis , and Dysphania ambrosioides , which are used by the local population of the western Himalayan region for medicinal pur…
Antimycobacterial and antimalarial activities of endophytic fungi associated with the ancient and narrowly endemic neotropical plant Vellozia gigantea from Brazil Open
Our results indicate that V. gigantea may represent a microhabitat repository hotspot of potential fungi producers of bioactive compounds and suggest that endophytic fungal communities might be an important biological component contributin…
Biological Activity of Bunium persicum Essential Oil from Western Himalaya Open
The essential oil of Bunium persicum collected from cultivated sources in the cold desert area of Lahaul-Spiti is described for its antimicrobial, larvicidal, and biting deterrent activities. Additionally, odor characterization is given. T…
