Mature stems of Diploclisia glaucescens contain 3.2% of their dry weight as 20E.
“Mature stems of Diploclisia glaucescens were found to contain 3.2% of its dry weight as 20E [166], but the collection of the stems of this South Asian climber precludes this as a feasible source of large amounts of 20E.”
From Ecdysteroids (2021) · cites this paper as [166]
Compound II was identified as ecdysterone, with 7.2 mg and 98.3% purity determined by HPLC.
“The separation produced 30.5 mg of paristerone with 99.1% purity, 7.2 mg of ecdysterone with 98.3% purity, and 8.1 mg of capitasterone with 98.1% purity determined by HPLC analysis.”
From Isolation and purification of three ecdysteroids from the stems of Diploclisia glaucescens by high-speed countercurrent chromatography and their anti-inflammatory activities in vitro (2017) · cites this paper as [11]
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.
