24-Epibrassinolide from Gypsophila perfoliata
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1996 Abstract The scarce 24-epibrassinolide could be identified from seeds of Gypsophila perfoliata L. by GC/MS as the only brassinosteroid present. Furthermore, the Δ7-phyto-sterols ergost-7-en-3β-ol, spinasterol and 22-dihydro-spinasterol were found as main sterols in the same plant material.

Synthesis of fatty acyl derivatives of 24-epibrassinolide
The Journal of Steroid Biochemistry and Molecular Biology, 2013A number of fatty acid (palmitic, myristic and lauric) esters (both 3α- and 3β-isomers) of epibrassinolide has been prepared as reference compounds for metabolic studies. Selective protection of the three of four hydroxyl groups of epibrassinolide was successively performed first as cyclic 22,23-methylboronates and then as 2α-benzyl ethers.

The effect of 24-epibrassinolide on the green alga Acutodesmus obliquus (Chlorophyceae)
Plant Physiology and Biochemistry, 2018Brassinosteroids play an important role in the plant growth and development as well as in the adaptation of plants to environmental stresses. Studies have shown the effect of 24-epibrassinolide (EBL) in the range of concentrations 0.0001-10 μM on the green unicellular alga Acutodesmus obliquus (Chlorophyceae) during 7 days of cultivation.
