Integrated Phytochemical Analysis Based on UPLC-MS/MS and Network Pharmacology Approaches to Explore the Effect of Odontites vulgaris Moench on Rheumatoid Arthritis.[Pubmed:34526896]

Front Pharmacol. 2021 Aug 30;12:707687.

Odontites vulgaris Moench has the effect of clearing away heat, detoxification, dispelling wind, and clearing dampness. In this study, the potential anti-inflammatory compounds of O. vulgaris were investigated using ultra-high-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) combined with the network pharmacology approach and further confirmed on an LPS-activated RAW 264.7 macrophage model. Monomer compounds were prepared from the active fraction using modern advanced separation and purification methods. UPLC-Q-Exactive HRMS was used to identify the chemical compounds in the active fractions of O. vulgaris. D-mannitol, geniposidic acid, salidroside, shanzhiside methyl ester, eleutheroside B, geniposide, 7,8-dihydroxycoumarin, Gardoside methyl ester, arenarioside, vanillic acid, p-hydroxy-cinnamic acid, melampyroside, syringaresinol, tricin, and diosmetin were isolated from O. vulgaris for the first time. A compound database of O. vulgaris was established based on the existing literature to predict the mechanism of O. vulgaris in the treatment of rheumatoid arthritis. The results suggest that the PI3K-Akt pathway mediates O. vulgaris and deserves more attention in the treatment of RA. Finally, the anti-rheumatoid arthritis effects of the four target compounds were validated with the decreased levels of NO, TNF-alpha, IL-6 and IL-1beta in RAW 264.7 macrophage cells treated with LPS. The present study explored the potential targets and signaling pathways of O. vulgaris in the treatment of RA, which may help to illustrate the mechanisms involved in the action of O. vulgaris and may provide a better understanding of the relationship between O. vulgaris and RA. This study provides novel insights into the development of new drugs and utilization of Mongolian traditional Chinese medicine resources.

Iridoids from Bellardia trixago (L.) All.[Pubmed:23298403]

Nat Prod Res. 2013 Aug;27(15):1413-6.

The phytochemical study of the polar fraction of Bellardia trixago (L.) All. led to the isolation of eight iridoid glucosides. Five of these glucosides (aucubin (1), bartsioside (2), melampyroside (3), mussaenoside (4) and Gardoside methyl ester (5)) were confirmed as they were previously isolated from this plant, and the remaining three known compounds (mussaenosidic acid (6), geniposidic acid (7) and 8-epiloganin (8)) were isolated here for the first time. Of particular interest were the presence of 7 and 8 due to two reasons: the first one because it is not accompanied with geniposide, the corresponding methyl ester, as in the case of 4 and 6, and the second one because it is the parent compound of iridoids characteristic of Orobanchaceae family. Also an alditol, D-mannitol (9), was recognised for the first time from this species.

Structural characterization of iridoid glucosides by ultra-performance liquid chromatography/electrospray ionization quadrupole time-of-flight tandem mass spectrometry.[Pubmed:18491284]

Rapid Commun Mass Spectrom. 2008 Jun;22(12):1941-54.

The mass spectral fragmentation behavior of ten iridoid glucosides (IGs) has been studied using electrospray ionization (ESI), collision-induced dissociation (CID), and quadrupole time-of-flight tandem mass spectrometry (Q-TOF MS/MS). In the negative ESI mass spectra, the deprotonated [M-H](-) ion was observed for all of the ten IGs except Gardoside methyl ester, while the formate adduct [M+HCOO](-) ion appeared to be favored by the presence of a methyl ester or a lactone group in the C-4 position when formic acid was added to the mobile phase. The CID MS/MS spectra of the [M-H](-) ions have been used for structural elucidation. Ring cleavages of the aglycone moiety have been observed in the MS/MS spectra, corresponding to (1,4)F(-), (2,6)F(-), (2,7)F(-), and (2,7)F(0) (-) ions, based on accurate mass measurements and the elemental compositions of the product ions. These characteristic ions gave valuable information on the basic structural skeletons. Furthermore, on the basis of the relative abundances of the fragment ions (1,4)F(-) and (2,7)F(-), different sub-classes, such as cyclopentane-type and 7,8-cyclopentene-type IGs, can be differentiated. Ring cleavage of the sugar moieties was also observed, yielding useful information for their characterization. In addition, the neutral losses, such as H(2)O, CO(2), CH(3)OH, CH(3)COOH, and glucosidic units, have proved useful for confirming the presence of functional substituents in the structures of the IGs. Based on the fragmentation patterns of these standard IGs, twelve IGs have been characterized in an extract of Hedyotis diffusa Willd. by means of ultra-performance liquid chromatography/Q-TOF MS/MS, of which six have been unambiguously identified and the other six have been tentatively identified.

Aragoside and iridoid glucosides from Aragoa cundinamarcensis.[Pubmed:12943770]

Phytochemistry. 2003 Sep;64(2):529-33.

From the water-soluble part of an extract of Aragoa cundinamarcensis were isolated seven iridoid glucosides, namely aucubin, catalpol, rehmannioside D, globularin, Gardoside methyl ester, epiloganin and mussaenoside. The main glycoside isolated, however, was a new caffeoyl phenylethanoid triglycoside, named aragoside, containing two beta-gluco- and one alpha-arabinopyranosyl moieties which constituted almost 5% of the dry weight of the plant. Finally, sorbitol was found to be the main carbohydrate constituent of the plant. This distinctive combination of compounds is very similar to that reported from some species of Plantago. The present findings therefore support the results from a recently published molecular phylogenetic study of plastid and nuclear ribosomal DNA sequences, where Aragoa was found to be the closest relative to Plantago so far discovered.

Phenylpropanoid and iridoid glycosides from Pedicularis spicata.[Pubmed:1367841]

Phytochemistry. 1991;30(11):3745-7.

One new phenylpropanoid glycoside, pedicularioside H, and five known glycosides, Gardoside methyl ester, shanzhiside methyl ester, 5-deoxypulchelloside I, verbascoside and pedicularioside A, were isolated from whole plants of Pedicularis spicata. On the basis of the spectral data, chemical evidence and comparison with authentic samples, pedicularioside H was determined to be 1'-O-beta-D-(3-methoxy-4-hydroxy-beta-phenyl)-ethyl-4'-O-feruloyl- beta-D- apiosyl(1----3')-alpha-L-rhamnosyl-(1----6')-glucopyranoside .

Hydrogenation of iridoid glucosides with exocyclic double bond.[Pubmed:17342604]

Planta Med. 1985 Oct;51(5):434-6.

Catalytic hydrogenation of two iridoids of unusual type with an exocyclic double bond, namely serrulatoloside and Gardoside methyl ester, over PtO (2) catalyst to give 10-desoxypatrinoside and 8-epiloganin, respectively, is described.
