Flavonoids of the fruits and leaves of Tribulus terrestris: Constitution of tribuloside

On-line (HPLC-NMR) and Off-line Phytochemical Profiling of the Australian Plant, Lasiopetalum macrophyllum

“…While the complete 2D NMR assignment of 16 is well documented, it is worth noting that on one occasion several of the carbon NMR assignments (namely positions C5, C6, C8 and C9) have been incorrectly assigned [36]. The NMR data as given in Table 1, and in particular the carbon chemical shift assignments, were confirmed on the basis of gHSQCAD and gHMBC NMR experiments and is consistent with all other literature NMR reports for 16 [30][31][32][33][34][35]. The sugar moiety in compound 16 was concluded to be a β-D-glucopyranoside on the basis of a comparison of the NMR chemical shifts for this moiety to the literature data [34].…”

Phytopharmacological overview of Tribulus terrestris

“…isolated kaempferol, kaempferol-3-glucoside, kaempferol-3-rutinoside, and tribuloside [kaempferol-3-β-d-(6″- p -coumaroyl) glucoside] from leaves as well as fruits and identified them by spectroscopic analysis. [10] Louveaux et al . detected 18 flavonoids (caffeoyl derivatives, quercetin glycosides, including rutin and kaempferol glycosides) using high-performance liquid chromatography (HPLC) in four Tribulus species leaf extracts.…”

Exploring glycolate oxidase (GOX) as an antiurolithic drug target: Molecular modeling and in vitro inhibitor study

“…Epidemiological studies are also convincing and shown positive correlations. The major constituents of Tt are steroidal saponins [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] and flavonoids [29,30]. Although the crude extracts of Tt was found to be effective in kidney stone management, a detailed study of its contents for therapeutic intervention of kidney stone is not sufficiently explored yet.…”
