Direct plant regeneration from different explants, micropropagation and determination of secondary metabolites were studied in the critically endangered endemic Rhaponticoides mykalea (Hub.-Mor.) M.V. Agab & Greuter. Seed germination was achieved by damaging the seed coat and cultivating the embryos on Woody Plant Medium (WPM), of which 40% germinated. The epicotyls and cotyledonary petioles of seedlings were used as initial explants and direct shoot regeneration was obtained on WPM containing 2.22 μM 6-benzyladenine (BA). WPM medium supplemented with 2.22 μM BA and 4.92 μM indole-3-butyric acid (IBA) significantly improved the production of multiple shoots, resulting in an average of 5.6 shoots per explants. The highest rooting of shoots (35.6%) was observed with WPM medium containing 19.68 μM IBA with 990 μM putrescine.Plantlets with well-developed roots were transferred to soil and acclimatised within a A c c e p t e d M a n u s c r i p t 2 plant growth chamber. Acclimatised plants showed 100% survival rate and remained healthy. As a part of our study, the content of secondary metabolites in three tissue culture regenerated lines were determined by HPLC analysis. Chlorogenic acid, Quercetin and scutellarin were confirmed secondary metabolites of R. mykalea.

“…Some of the compounds obtained from other Centaurea species include quercetin from C. omphalotricha [11], luteolin and apigenin and kaempferol from C. urvillei subsp. urvillei [12], rutin and chlorogenic acid from C. calolepis [13], protocatechuic acid from C. isaurica [14], chlorogenic acid from C. cadmea [15], and C. isaurica [14], vanillin from C. sadleriana [16]. To the best of our knowledge, none of these earlier studies used LC-MS/MS in determination of phytochemical compositions of the plant species.…”

“…Previous reports indicate isolation of flavonoids 6,7 , sesquiterpene lactones (guaianolides, germacronolides) 7-12 , triterpenes 7 and alkaloids 13 from Centaurea species. Previous reports on the essential oil composition of Centaurea species indicate main components as caryophyllene 14,15 , spathulenol 16,17 , eudesmol [17][18][19] , germacrene 16,20-24 as sesquiterpenes; hexadecanoic acid 5,18,[25][26][27][28][29][30][31][32][33][34][35] , tetradecanoic acid 29 , dodecanoic acid 26,29,33 as fatty acids; heptacosane 5,17,22,25,31,35,36 , tricosane 22,31,35 , pentacosane 22 , nonacosane 5 as higher alkanes and pinenes 16 , terpinenes 16 , carvacrol 29 as monoterpenes.…”

Essential oil composition of Centaurea stenolepis Kerner flowers and stems were investigated with GC, GC-MS. Flowers and stems of C. stenolepis had very low essential oil yield <0.01 % (v/w). Twenty eight compounds were identified in the flower oil which represent 53.5 % of the oil. Main components of the flower oil include caryophyllene oxide 12.6 %, hexadecanoic acid 10.6 % and β-Eudesmol 7.2 %. Forty compounds were identified in the stem oils which represent 74.2 % of the oil. Main components of the stem oils include hexadecanoic acid 38.4 % and phytol 12.9 %. Both flower and stem oils were rich on oxygenated sesquiterpene hydrocarbons and fatty acids.
