Phytoecdysteroids of Diploclisia glaucescens Seed
Abstract
Five phytoecdysteroids were isolated from the seeds of DIPLOCLISIA GLAUCESCENS and identified by spectrometric methods ( (1)H-NMR, (13)C-NMR and CIMS). One of them, 24- EPI- makisterone A, has not been reported before. The other four - 20-hydroxyecdysone, makisterone A, 24(28)-dehydromakisterone A and pterosterone - were known previously. The (13)C-NMR spectrum of 24(28)-dehydromakisterone A is presented for the first time.

Conventional methods for isolating ecdysteroids from D. glaucescens consumed large quantities of organic solvents and often offered low recoveries of the target products.
“Unfortunately, the conventional methods consumed large quantities of organic solvents, and often offer low recoveries of the target products.”

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.
