“…The (À)ESI/TOF mass spectra showed pseudo-molecular ions ([M À H] À ) at m/z 521.1350, 359.0763, 285.0405 and 269.0458, for rosmarinic acid-3-O-glucoside (4), rosmarinic acid (5), luteolin (7) and apigenin (8), respectively. Their MS/MS behaviours were identical to previous reports: m/z 521 → 359, 323 and 161 for rosmarinic acid-3-O-glucoside; m/z 359 → 161 and 197 for rosmarinic acid; m/z 285 for luteolin; and m/z 269 for apigenin (Olivier et al, 2008;Gu et al, 2009;Lin and Harnly, 2010;Kang and Lee, 2011;Lee et al, 2013), as depicted in Fig. S1.…”

“…Identification of their structures was achieved by comparing their MS behaviours, UV spectra and retention times with reference standards. The unknown compounds were tentatively identified by their chromatographic, UV and MS spectrometric data, by reference to previous studies (Nishimura et al, 1995;March et al, 2006;Olivier et al, 2008;Lin and Harnly, 2010;Kang and Lee, 2011;Ha et al, 2012;Pereira et al, 2012;Lee et al, 2013). Caffeic acid-3-O-glucoside (compound 1, t R = 3.6 min) and caffeic acid (compound 2, t R = 8.6 min) showed maximum UV absorption around 325 nm.…”

“…In (−)ESI/MS/MS, 1 and 2 generated [M − H] − ions at m/z 341.0888 and 179.0349, respectively, which were predicted as C 15 H 18 O 9 and C 9 H 8 O 4 . The major fragmentation of 1 ( m/z 341.0888) was at m/z 179 ([M − H − 162] − ), indicating loss of a glucose moiety (C 6 H 10 O 5 ) (Nishimura et al, 1 995; Olivier et al, ; Kang and Lee, ; Ha et al, ; Lee et al, ). In addition, the [M + Na] + ions were found for both 1 and 2 at m/z 365.0832 and 203.0328, respectively.…”

“…Several studies have reported the presence of caffeic acid in the leaves and tubers of various cultivars of sweet potato [ 31 , 32 ]. Caffeic acid has been identified as a potent antioxidant agent in plants [ 33 , 34 ]. Olivier and colleagues [ 35 ] reported the presence of caffeic acid in species of Arctopus and Alepidea which are important South African medicinal plants.…”

Aqueous-Methanol Extracts of Orange-Fleshed Sweet Potato (Ipomoea batatas) Ameliorate Oxidative Stress and Modulate Type 2 Diabetes Associated Genes in Insulin Resistant C2C12 Cells

Edible plants such as sweet potato are sources of natural antioxidants that can be exploited in the management and treatment of insulin resistance. This present study investigated the effects of the extracts of an orange-fleshed sweet potato on oxidative stress biomarkers (glutathione status and lipid peroxidation) and activities of antioxidant enzymes (catalase, CAT and glutathione peroxidase, GPx) in palmitate-induced insulin resistant C2C12 cells. The intracellular antioxidant status of the cells was also measured using Ferric reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) assays. Furthermore, this study determined the effect of the extracts on the regulation of some type 2 diabetes associated genes; glucose transporter 4 (glut4), Nuclear respiratory factor 1 (nrf1), Myocyte enhanced factor 2A (mef2a), Carnitine palmitoyltransferase 1 (cpt1) and Acetyl-CoA carboxylase 2 (acc2). The results showed a significant (p < 0.05) increase in intracellular GSH level, a significant reduction in the level of malonaldehyde and a significant improvement in the intracellular antioxidant status upon treatment of the insulin resistant cells with the extracts. The extracts were also able to positively modulate the expression levels of the type 2 diabetes associated genes. On the other hand, HPLC-MS analysis of the extracts showed the presence of polyphenols which could have contributed to the bioactivity of the extracts through their antioxidant effects.

“…[1][2][6] [7] Principle component analysis (PCA) has been successfully applied for distinguishing, for instance, Angelica sinensis from related Apiaceae herbs based on their chromatographic profiles and coniferyl ferulate amount. [8] Olivier et al [9] used rosmarinic acid and its derivatives for the chemotaxonomical differentiation in Apiaceae subfamilies. Chemotaxonomic classification has also been applied for quality control of grapevines, tomatoes, flowers, and medicinal herbs.…”

Melanoselinum decipiens and Monizia edulis (Apiaceae) are two endemic plants from Madeira archipelago, phytochemical compositions of which remains little explored, despite their use in folk medicine. Using liquid chromatography with diode array and electrospray ionization/mass spectrometry analysis, their polyphenolic profile was established for the first time. Fifty-six compounds were identified with 5-O-caffeoylquinic acid, quercetin-O-(malonyl)hexoside, luteolin diacetyl, and quercetin-O-hexoside being the major constituents in the leaves of both plant species (≥ 0.76 mg/g of dry extract). Principal component analysis provided a suitable tool to differentiate targeted plants. Naringenin-6,8-di-C-glucoside, quercetin 3-O-pentosylhexoside, and 1,5-O-dicaffeoylquinic acid can be used as discriminatory taxonomic/geographical markers for M. edulis subspecies from Madeira and Porto Santo populations. This methodology of using polyphenols as chemotaxonomic markers proved to be useful for identification of plant species since the results are consistent with previous taxonomical data. The free-radical scavenging activities of the M. decipiens extracts proved to be higher than those of M. edulis, which correlated well with their phenolic content (R > 0.906).
