“…The natural occurrence of hydroxycinnamoyldiglycerides in plants seems to be restricted to a small number of species among the Poaceae, Liliaceae, Sparganiaceae and Bromeliaceae [55]. In particular, representatives of these species are adapted to hot and/or arid climates and habitats such as sorghum (Sorghum bicolor (L.) Moench), Tillandsia spp.…”

In a comprehensive study, more than 60 phenolic compounds were detected in methanolic extracts from different tissues of pineapple infructescence by high-performance liquid chromatography with diode array detection and electrospray ionisation multiple-stage mass spectrometry (HPLC-DAD-ESI-MS (n) ) as well as by gas chromatography-mass spectrometry (GC-MS). The analytical workflow combining both methods revealed numerous compounds assigned for the first time as pineapple constituents by their mass fragmentations. Pineapple crown tissue was characterised by depsides of p-coumaric and ferulic acid. In contrast, major phenolic compounds in pineapple pulp extracts were assigned to diverse S-p-coumaryl, S-coniferyl and S-sinapyl derivatives of glutathione, N-L-γ-glutamyl-L-cysteine and L-cysteine, which were also identified in the peel. The latter was additionally characterised by elevated concentrations of p-coumaric, ferulic and caffeic acid depsides and glycerides, respectively. Two peel-specific cyanidin hexosides were found. Elevated concentrations of isomeric N,N'-diferuloylspermidines may be a useful tool for the detection of fraudulent peel usage for pineapple juice production. Mass fragmentation pathways of characteristic pineapple constituents are proposed, and their putative biological functions are discussed.

“…Therefore, SA4 was identified to be an glycerol ester with two acid units, one being caffeic acid and the other p‐coumaric acid. In comparison of the data with the literature value (Cooper, Gottlieb, & Lavie, ; Delaporte, Guzen, Laverde, Santos, & Sarragiotto, ), the compound SA4 was concluded to be 1‐O‐p‐coumaroyl‐3‐O‐caffeoylglycerol (Figure b).…”

This study investigated bioactive secondary metabolites from the aerial parts of Cymbopogon flexuosus (CF). Total phenolic and total flavonoid contents, the antioxidant activities including 2, 2′‐azino‐bis (3‐ethylbenzthiazoline‐6‐sulfonic acid) (ABTS+) and 2, 2′‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging systems, and cytotoxic effects were determined. 1, 3‐O‐di‐E‐caffeoylglycerol (SA3) and 1‐O‐p‐coumaroyl‐3‐O‐caffeoylglycerol (SA4) were firstly isolated from an ethanol extract of CF. Their chemical structures were elucidated by extensive spectroscopic analyses, including MS and NMR spectra as well as by comparison to the data reported in the literature. DPPH and ABTS+ radical scavenging tests showed that the highest antioxidant potent was detected for compound SA3 with IC50 of 4.42 ± 0.18 and 21.84 ± 0.22 µg/ml, respectively. The compound SA3 stimulated the apoptotic factors of caspase‐3, bax, and bcl‐2 in HepG2 and caspase‐3, caspase‐9, P53 in A549. Practical applications CF has been widely used as both a herbal drink and as a spice in diets. In the food processing industry, CF was used to process candy. In addition, it is used for the treatment of sore throat, cough, skin diseases, and other diseases in traditional oriental medicine. Recently, in Vietnam, CF has also been used to treat liver and lung cancer and consumed daily to process many dishes.

“…Its IR spectrum indicated the presence of hydroxyl (3023 cm -1 ), ester carbonyl (1683 cm -1 ) and aromatic rings (1601 and 1512 cm -1 ). Analysis of the 1 H and 13 C NMR spectrum (Table II) of compound 2 suggested its structure is closely related to that of 1-O-feruloyl-3-O-p-coumaroylglycerol (Delaporte et al, 2006), except that the 7' and 8' protons of the feruloyl moiety had different chemical shifts and coupling constant. In the 1 H NMR spectrum of 2, one pair of signals for olefinic protons appeared at δ H 5.82 and 6.86 (each 1H, d, J = 12.8 Hz).…”
