Sesquiterpene Lactones as Allelochemicals
Journal of Natural Products, 2006Six new sesquiterpene lactones, annuolide H (3), helivypolides F, H-J (4, 11-13), and helieudesmanolide A (6), together with known compounds, were isolated from polar bioactive fractions of Helianthus annuus cv. SH-222 and Stella fresh leaf water extracts.

Allelochemical Potential of Callicarpa acuminata
Journal of Chemical Ecology, 2003The allelochemical potential of Callicarpa acuminata (Verbenaceae) was investigated by using a biodirected fractionation study as part of a long-term project to search for bioactive compounds among the rich biodiversity of plant communities in the Ecological Reserve El Eden, Quintana Roo, Mexico.

Allelochemicals fromPilocarpus goudotianus leaves
Journal of Chemical Ecology, 1993The effect on germination, shoot, and root growth by bergapten, xanthotoxin, imperatorin, xanthyletin, xanthoxyletin, luvangetin, donatin and alloxanthoxyletol fromPilocarpus goudotianus leaves, onLactuca sativa var. nigra seedlings has been evaluated. A structure-activity correlation is discussed based on the bioassay results.

Mineralization of the allelochemical sorgoleone in soil
Chemosphere, 2009The allelochemical sorgoleone is produced in and released from the root hairs of sorghum (Sorghum bicolor). Studies have confirmed that it is the release of sorgoleone that causes the phytotoxic properties of sorghum, and sorgoleone has a potential to become a new natural herbicide, or the weed suppressive activity of sorghum can be utilized in ...

Lignin and polyphenols as allelochemicals
Industrial Crops and Products, 2008By the microbiological action, lignin from vegetal wastes is transformed at soil level in organic prebiotic products with physiological activity on plants development. On the other hand, some micromolecular compounds resulted from plant wastes decomposition, along with polyphenols coming from extraction of plant residues could play a role of ...

Potential allelochemicals from Sambucus nigra
Phytochemistry, 2001Twenty-four aromatic metabolites belonging to cyanogenins, lignans, flavonoids, and phenolic glycosides were obtained from Sambucus nigra. Structures were determined on the basis of their spectroscopic features. Two compounds have been isolated and identified as (2S)-2-O-beta-D-glucopyranosyl-2-hydroxyphenylacetic acid and benzyl 2-O-beta-D ...
