“…These results are in agreement with previous studies performed on Astragalus species (Ö zipek et al, 2005;Pistelli et al, 2003). The phytochemical investigation of A. gombo confirms the occurrence of cycloartane triterpene glycosides in the Astragalus genus.…”

“…Previous phytochemical investigations on Astragalus genus revealed the presence of saponins, polysaccharides, phenolics and alkaloids. [2][3][4][5] In continuation of on-going studies on the constituents of Astragalus species, [6][7][8] a phytochemical study on Astragalus monspessulanus L. was realized.…”

This paper reports a phytochemical study of the aerial parts of Astragalus monspessulanus L. growing in Algeria. It deals with the isolation and structure elucidation of 13 known compounds. From the n-butanol extract, seven flavonoids 1-7, two saponins and one lignan were isolated. In addition, two phytosterols and one triterpenoid were isolated from the ethyl acetate extract. The structures of all the isolated products were determined by using 1D and 2D-NMR techniques, measurement of optical rotation, mass spectrometry ESI-MS and by comparison with literature data. Furthermore, the antioxidant activity of the n-butanol extract of the aerial parts of Astragalus monspessulanus L. was investigated using the DPPH radical scavenging and ferrous ion chelating assays. The n-butanol extract showed low (EC 50 = 2.09±0.434 mg mL -1 ) to moderate (IC 50 = 63.60±0.01 μg mL -1 ) antioxidant activities depending on the test method.

“…In addition, the pentose signals of 27 and 38 were changed as well. According to the literature, the pentose in the structures of 27 and 38 was elucidated to be β- d -apiofuranosyl [ 19 ]. The HSQC, and HSQC-TOCSY combined with COSY spectra were used for the assignment of glycosyl units.…”

Yucca schidigera Roezl (Mojave), a kind of ornamental plant belonging to the Yucca genus (Agavaceae), whose extract exhibits important roles in food, beverage, cosmetic and feed additives owing to its rich spirostanol saponins. To provide a comprehensive chemical profiling of the spirostanol saponins in it, this study was performed by using a multi-phase liquid chromatography method combining a reversed phase chromatography T3 column with a normal phase chromatography silica column for the separation and an ESI-Q-Exactive-Orbitrap MS in positive ion mode as the detector. By comparing the retention time and ion fragments with standards, thirty-one spirostanol saponins were identified. In addition, according to the summary of the chromatographic retention behaviors and the MS/MS cleavage patterns and biosynthetic pathway, another seventy-nine spirostanol saponins were speculatively identified, forty ones of which were potentially new ones. Moreover, ten novel spirostanol saponins (three pairs of (25R/S)-spirostanol saponin isomer mixtures) were targeted for isolation to verify the speculation. Then, the comprehensive chemical profiling of spirostanol saponins from Y. schidigera was reported here firstly.
