Allelochemicals fromPilocarpus goudotianus leaves

Journal of Chemical Ecology, 1993
The 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.

Sesquiterpene Lactones as Allelochemicals

Journal of Natural Products, 2006
Six 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.

Potential allelochemicals from Sambucus nigra

Phytochemistry, 2001
Twenty-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 ...

Fungal allelochemicals in insect pest management

Applied Microbiology and Biotechnology, 2016
Interactions between insects and fungi are widespread, and important mediators of these interactions are fungal chemicals that can therefore be considered as allelochemicals. Numerous studies suggest that fungal chemicals can affect insects in many different ways.

Searching for Rice Allelochemicals

Agronomy Journal, 2001
A bioactivity‐guided isolation method was developed with the objective of isolating the allelochemicals in rice (Oryza sativa L.). Roots of the allelopathic rice cultivar Taichung Native 1, grown hydroponically, were extracted and fractionated, with the activity of the fractions followed using a 24‐well culture plate microbioassay.
