Studies on the Essential Oil of Artemisia annua L. I: Isolation of a New Ester Compound
Open accessAbstract
A new ester of b. p6 74-76° was isolated as the essential oil component of Artemisia annua L. (Compositae) and its hydrolysis afforded acetic acid and a new alcohol compound, C10H18O, b.p6 71° [α]D20-31.8°, nD20 1.4640. This alcohol colored yellow with tetranitromethane, decolorized potassium permanganate and bromine, and a presence of two double bonds in its molecule was assumed from its infrared spectrum and molecular refraction.

A. annua is a rich source of unusual irregular acyclic monoterpenoids, such as artemisia ketone.
“Phytochemists were interested in A. annua before the discovery of artemisinin because it is a rich source of unusual irregular acyclic monoterpenoids, such as artemisia ketone (276) [115,116,117,118,119,120]”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
