Abstract

Background: Occurrence of integristerone A (1), 20‑hydroxyecdysone (2), ecdysone (3), 2‑deoxy‑20‑hydroxyecdysone (4) has been analyzed in 64 species of the East Asian Caryophyllaceae.Materials and Methods: Ecdysteroid content was determinate by high‑performance liquid chromatography (HPLC). HPLC with a high‑resolution mass spectrometry was performed on Shimadzu LCMS‑IT‑TOF (Japan) system equipped with a LC‑20A Prominence liquid chromatograph, a photodiode array detector SPD‑M20A and ion‑trap/time‑of‑flight mass spectrometer.Results: New sources of phytoecdysteroids: Melandrium sachalinense and Melandrium firmum have been revealed. It is the 1st time that two has been identified in M. sachalinense and M. firmum; 1 in the species: Lychnis fulgens, Silene repens, Silene foliosa, Silene stenophylla, Silene jenisseensis and M. sachalinense; 3 in Lychnis cognata; 4 in L. fulgens, S. stenophylla and S. jenisseensis (the tribe Lychnideae, the subfamily Caryophylloideae). Ecdysteroid‑negative taxa are Spergularia rubra of the tribe Sperguleae; species of the genera Minuartia, Honckenya, Eremogone, Arenaria, Moehringia, Pseudostellaria, Fimbripetalum, Stellaria and Cerastium of the tribe Alsineae; Scleranthus annuus of the tribe Sclerantheae, as well as the East Asian representatives of the genera Gypsophila, Psammophiliela, Dianthus and Saponaria of the tribe Diantheae; Oberna and Agrostemma of the tribe Lychnideae.Conclusion: This investigation shows the most promising sources of ecdysteriods are species of genera Silene and Lychnis.
