Antioxidant and biocidal activities of Carum nigrum (seed) essential oil, oleoresin, and their selected components.
TLDR
Both oil and oleoresin could be used as an additive in food and pharmaceutical preparations after screening and were able to reduce the oxidation rate of the mustard oil in the accelerated condition at 60 degrees C in comparison with synthetic antioxidants.

Three new diterpenoids based on the novel sarcopetalane skeleton from Croton sarcopetalus.
The roots of Croton sarcopetalus afforded three new diterpenoids (2-4) with a novel carbon skeleton that seems to be derived biosynthetically from a pimarane precursor. The essential oil of the roots…
