Iridoid glycosides from Cephalaria kotschyi roots

Extracts from Cephalaria Uralensis (Murray) Roem. & Schult. and Cephalaria Gigantea (Ledeb.) Bobrov as Potential Agents for Treatment of Acne Vulgaris: Chemical Characterization and In Vitro Biological Evaluation

“…These annual and perennial plants [ 17 , 18 ] occur mainly in Europe, East Asia, East Mediterranean and Central Africa [ 19 ]. Cephalaria species are rich in triterpene saponins [ 20 , 21 , 22 , 23 ], iridoids [ 24 ], alkaloids [ 25 ] and flavonoids [ 26 ], which are responsible for, for example, cytotoxic [ 23 , 27 ], immunomodulatory [ 23 ], antibacterial [ 17 , 28 ], antifungal [ 29 ] and hypoglycemic [ 30 ] activities.…”

Effects of post-treatment with alkaline copper quat and copper azole on the mechanical properties of wood-based composites

“…side II, 8). 14 One triterpenic metabolite oleanolic acid (9) 22 (Figure 1); 1 flavone glycoside, quercetin 3-Orutinoside (10); 23 and 3 iridoid compounds, iridoid aglycon (11), 24 loganin (12), 18 and laciniatoside I (13) 24 (Figure 2) were identified by spectral methods including 1D-, 2D-NMR, and HRESI-MS techniques and some chemical examinations. These compounds were tested for their antimicrobial effects against gram-positive and gram-negative bacteria.…”

Chemical constituents from the roots of Cephalaria kotschyi

“…Earlier phytochemical studies reported the isolation of triterpene saponins, flavonoids, and gentianine type alkaloids from the roots and flowers of C. kotschyi [1][2][3][4][5][6][7]. In our previous study we described the isolation of the iridoid glycosides loganin and gentiopicroside from the roots of this plant [8].…”

In our previous study we described the isolation of the iridoid glycosides loganin and gentiopicroside from the roots of this plant [8].Herein we report, together with the gentiopicroside and loganin described previously, the isolation of three iridoid and secoiridoid glycosides: loganic acid [9], swertiamarin [10], and cantleyoside [11]; two furofuranic lignans: prinsepiol glycoside [12] and 8-hydroxypinoresinol-4c-O-E-D-glucoside [13]; and two triterpene saponins: giganteoside Jc [14] and dipsacoside B [15], from an investigation of the chemical constituents of the roots of C. kotschyi. The plant was collected in the Lerik region of Azerbaijan in September 2005.…”
