Description of this data

The influence of laboratory isolated and identified SME, ASME and IFBp, from Barleria prionitis aerial part, on the production and release of pro-inflammatory mediators i.e. myeloperoxidase (MPO), elastase, matrix metalloproteinase 9 (MMP-9), interleukin 8 (IL-8), tumor necrosis factor alpha (TNF-α) and leukotriene B4 (LTB4) was evaluated in the formyl-met-leu-phenylalanine (f-MLP) and lipopolysaccharide (LPS) stimulated human neutrophils using ELISA reader.

Both SME and ASME were isolated and characterized from the IFBp. SME was isolated as white amorphous powder melted at 120–121°C with UV (MeOH) λmax, 236 nm; IR (KBr) nmax, 3404 cm–1 (–OH), 1687 cm–1 (ester carbonyl), 1645 cm–1 (enol–ether system) and positive ESI-MS, m/z (rel. int.): 835 [2M+Na]+ (8); 445 [M+K]+ (8); 429 [M+Na]+ (100), (C17H26O11 requires 406). While ASME was isolated as colorless crystals melted at 180–181°C with UV (MeOH) λmax, 235 nm; IR (KBr) nmax 3400 cm–1 (–OH), 1701 cm–1 (ester carbonyl), 1635 cm–1 (enol–ether system) and positive ESI-MS, m/z (rel. int.): 919 [2M+Na]+ (12), 487 [M+K]+ (8), and 471 [M+Na]+ (100) (C19H28O12 requires 448). Identity of SME and ASME was confirmed by comparison of their spectral analysis data (UV, FTIR, 1H NMR and 13C NMR, and positive ESI-MS) with that reported in the literature (Ghule et al., 2012; Damtoft et al., 1982; Taneja and Tiwari, 1975). Fig. 1 depicts the chemical structures of these laboratory isolated and identified compounds and the supplementary spectral data is shown in Fig. S1 (UV VIS spectra), Fig. S2 (FTIR spectra), Fig. S3 (1H-NMR spectra), Fig. S4 (13C-NMR spectra), Table S1 (1H- and 13C-NMR spectral data), Fig. S5 (positive ESI-MS spectra) of SME and ASME isolated and characterized from IFBp.

Using SME and ASME as laboratory isolated and identified marker compounds of B. prionitis, a HPTLC method was validated following the guidelines of the International Conference on Harmonization.
