“…The ESI-MS/MS spectrum (of the compound corresponding to peak 8 with t r of 8.6 min (Table 1 and Figure 4), showed an [M-H] − ion at m/z 925 and fragment ions at m/z 793 [M-H-132] − and at m/z 763 [M-H-162] − attributed to loss of an arabinose moiety and a glucose moiety, respectively. These results suggest that the compound might be an oleanane-type triterpenoid saponin such as chikusetsusaponin IV (3- O -α- L -arabinopyranosyl-(1→4)-β- d -glucuronopyranosyl-28- O -β- d -gluco-pyranosyl oleanolic acid) or its isomers, according to the literature [38,61]. Further investigations by NMR methods are needed to confirm the absolute configuration of the isomeric compounds, especially to define the position of the sugar moiety.…”

Phytochemical Analysis of Pfaffia glomerata Inflorescences by LC-ESI-MS/MS

Pfaffia glomerata contains high levels of β-ecdysone, which has shown a range of beneficial pharmacological effects. The present study demonstrated that inflorescences of P. glomerata contain other important bioactive compounds in addition to β-ecdysone. The identification of compounds from inflorescences using liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) was performed for the first time. The eight compounds identified were β-ecdysone, flavonoid glycosides such as quercetin-3-O-glucoside, kaempferol-3-O-glucoside and kaempferol-3-O-(6-pcoumaroyl)-glucoside, oleanane-type triterpenoid saponins such as ginsenoside Ro and chikusetsusaponin IV, in addition to oleanonic acid and gluconic acid. This study provided information on the phytochemicals contained in P. glomerata inflorescences revealing the potential application of this plant part as raw material for the phytotherapeutic and cosmetic industries.

“…anthocyanins, proanthocyanidins, catechins, and stilbenes. 1 In recent years, the effect of stilbenoids on human health has been considered to be of great interest. These metabolites have been found in different parts of the plant (shoots, infected leaves, rachids), but their concentration is usually low and widely variable.…”

Cell suspension cultures of Vitis vinifera L., particularly after elicitation, have shown the ability to biosynthesize several stilbenoids. In this work the application of specific tandem mass spectrometry (MS/MS) experiments and the integration with data from UV-vis spectra, available only for the main compounds of the extract, allowed the detection of over 20 different stilbenoids. Up to eight monoglicosides, both monomers and dimers, a high number of dimer forms (up to 17), belonging to the group of viniferins and to their oxidized derivatives, were identified in the extract of Malvasia cell cultures. Moreover, the selectivity and sensitivity of the method allowed detection also of a few cis derivatives (up to 3) present in very low concentrations and presumably produced by the light exposure during treatment of the sample. To the best of the authors' knowledge, there are no literature data on MS/MS experiments targeted to simultaneously study monomeric and dimeric stilbenoids, both as free and glycosilated forms, in a complex mixture from V. vinifera cell suspension cultures.

The chemical constituents of Symplocos genus were reviewed with 90 structures and 28 references cited. These constituents include triterpenoids, flavonoids, lignans, phenols, steroids, alkaloids, and iridoids. Triterpenoids are the dominant constituents within the genus Symplocos, some of them exhibited antiproliferative effects. Some phenolic glycoside derivatives showed inhibitory activity against snake-venom phosphodiesterase I and human nucleotide pyrophosphatase phosphodiesterase.
