Ecdysteroids from Cyanotis longifolia Benth. (Commelinaceae)
Abstract
Cyanotis longifolia Benth. (Commelinaceae) contains ecdysteroids, which are highly concentrated in the roots and flowers, whereas leaves contain only very low amounts and stems intermediate amounts. 20-Hydroxyecdysone is the major component found in all tissues, but roots also contain large amounts of 20-hydroxyecdysone 3-acetate and ajugasterone C. A preparative experiment has shown that roots contain a complex ecdysteroid mixture, and the analysis of minor components has allowed the isolation of several already known ecdysteroids (polypodine B, 2-deoxy-20,26-dihydroxyecdysone, isovitexirone, poststerone) together with five new (ajugasterone C 3-acetate, 5beta-hydroxy-poststerone, poststerone 2-acetate, 14(15)-dehydro-poststerone 2-acetate, 24-epi-atrotosterone A [=24-methyl-ajugasterone C]) ecdysteroids that have been fully characterized. A preliminary investigation of 55 species belonging to 15 different genera of the Commelinaceae has shown that several of them contain significant concentrations of ecdysteroids, among which some previously uninvestigated ones appear to be very promising sources of ecdysteroids.

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.
