Natural products in crop protection.
Quantification of saffron (Crocus sativus L.) metabolites crocins, picrocrocin and safranal for quality determination of the spice grown under different environmental Moroccan conditions
Antimycobacterial plant terpenoids.
This review covers recent reports on plant-derived terpenoids that have demonstrated moderate to high activity in in vitro bioassays against M. tuberculosis and focuses on the structural features essential for antimycobacterial activity.
Diversity and bioprospecting of fungal communities associated with endemic and cold-adapted macroalgae in Antarctica
The results suggest that the endemic and cold- Adapted macroalgae of Antarctica shelter a rich, diversity and complex fungal communities consisting of a few dominant indigenous or mesophilic cold-adapted species, and a large number of rare and/or endemic taxa, which may provide an interesting model of algal–fungal interactions under extreme conditions as well as a potential source of bioactive compounds.
Natural products as sources for new pesticides.
Despite the common perception that natural products may not be the best sources for NAI as pesticides, when both conventional and biopesticides are examined collectively, it can be argued that their combined impact with the EPA from 1997 to 2010 accounted for 69.3% of all NAI registrations.

The results demonstrated that basil could be a viable essential oil crop in Mississippi and the availability of various chemotypes offers the opportunity for production of basil to meet the market requirements of specific basil oils or individual compounds such as (-)-linalool, eugenol, methyl chavicol, methyl cinnamate, or methyl Eugenol.
Content, composition, and bioactivity of the essential oils of three basil genotypes as a function of harvesting.

Essential oils from both species grown in Mississippi showed in vitro activity against Leishmania donovani, which was comparable to the activity of commercial oil (IC50 = 40-50 microg/mL).
Bioactivity-guided fractionation and GC/MS fingerprinting of Angelica sinensis and Angelica archangelica root components for antifungal and mosquito deterrent activity.
Phthalides and monoterpene hydrocarbons were determined to be good systematic markers or chemical fingerprints for A. sinensis and A. archangelica root oils and deterred the biting of two mosquito species more effectively than DEET.
Effects of the macroalga Asparagopsis taxiformis and oregano leaves on methane emission, rumen fermentation, and lactational performance of dairy cows.
Asparagopsis taxiformis (AT) is a source of multiple halogenated compounds and, in a limited number of studies, has been shown to decrease enteric CH4 emission in vitro and in vivo. Similarly,…
Structure–Activity Relationship Studies on Derivatives of Eudesmanolides from Inula helenium as Toxicants against Aedes aegypti Larvae and Adults
An Aedes aegypti larval toxicity bioassay was performed on compounds representing many classes of natural compounds including polyacetylenes, phytosterols, flavonoids, sesquiterpenoid, and triterpenoids to understand the functional groups necessary for maintaining and/or increasing its activity, and to possibly lead to more effective insect‐control agents.
