“…The aqueous ethanolic extract of the whole plants of E. wallchii was separated repeatedly by column chromatography on silica gel to give 28-epi-cyasterone (1A), eriophytonoide (2), as well as cyasterone (1B), ajufor- (10), ␤-sitosterol (11), and daucosterol (12).…”

“…5). The known compounds ajuforrestins A (3) and B (4) [8], 20-hydroxyecdysone (5) [9][10][11], polypodin B (6) [9,12], ajugalactone (7) [4], 8-O-acetylharpagid (8) [13,14], and N- [2-hydroxy-(nonadecanoyl-tricosanoyl)]-4-hydroxytrans-8-sphingenine (10) [5] were identified by their spectral data and by comparison with previously reported data. Apigenin (9), ␤-sitosterol (11), and daucosterol (12) were identified by their spectral data and by co-TLC with authentic samples.…”

“…In order to find the active compounds of this folk medicine, a phytochemical investigation was carried out on the aqueous ethanolic extract of E. wallchii. This study led to the isolation of a new phytoecdysteroid 28-epi-cyasterone (1A), a new glycoceramide eriophytonoide (2), and 11 known compounds, cyasterone (1B), ajuforrestins A (3) and B (4), 20-hydroxyecdysone (5), polypodin B (6), ajugalactone (7), 8-O-acetylharpagid (8), apigenin (9), N- [2- (10), ␤-sitosterol (11), and daucosterol (12). Their structures were elucidated on the basis of spectral and chemical evidence.…”

“…Also, previous phytochemical studies, several compounds have been identified and isolated from the different parts of the plant, including phytoecdysteroids (Girault et al 1990, Ba´thori et al 2001, Louden et al 2001, Zibareva et al 2003, saponins (Wagner 1941), triterpenoids (Bucharov et al 1974) as well as phenolic acids (Ferry and Darbour 1979). Additionally, analysis of the volatiles of L. flos-cuculi flowers showed that the dominating compound classes are benzenoids, followed by fatty acid derivatives (Jurgens 2004).…”

Lychnis cognate Maxim and Lychnis fulgens Fish. Ex Spreng are two valued ornamental plants in Korea. Soaking of seeds in GA 3 solution remarkably promoted germination up to 60%, but the control (0 mg/l) was not effective (> 5%). To select an adequate temperature for seed germination, seeds, previously soaked in a 1000 mg/l GA 3 for 24 hrs, were incubated at 15, 20, 25, and 30°C. Seed germination of over 20% was obtained at 15, 20, and 25°C, but only 10% at 30°C. These results indicate that the seeds of L. cognate and L. fulgens are in a such dormant state that they hardly germinate even by dormancy breaker (GA 3 ) and low (15 -25°C) temperature treatment. The highest callus induction was observed in the leaf explants of the seedlings on MS containing specific concentrations of 3.0 mg/l BA and 1.0 mg/l NAA. The adventitious shoot was formed < 90% of calli on 1/2 WPM medium. The height of in vitro propagated plantlet was no different media used for regeneration. This in vitro propagation protocol should be useful for conservation of endangered and ornamental plant.
