Phenylpropanoid glucosides from leaves of Coussarea hydrangeifolia (Rubiaceae)

Chemical Constituents from Thalictrum ramosum

“…C-1'), 102.3 (C-1''), 78.0 (C-3'), 76.9 (C-5'), 75.1 (C-2'), 74.0 (C-4''),72.3 (C-3''), 72.2 (C-2''),71.8 (C-7), 71.7 (C-4'), 69.8 (C-5''), 68.1 (C-6') and 18.1 (C-6''). These data were consistent those in the literature [15]. So, compound 9 was elucidated as hydrangeifolin I (Figure 1).…”

Study on water soluble constituentsfrom Gomphrena celoisiodes

“…Compounds 3-4 have a -CH2-CH2-unit confirming by signals at 2.96 (2H), 4.06/3.79 (2H) for 3 and 2.94 (2H), 4.08/3.78 (2H) for 4, while compound 5 has only a -CH2-unit at 4.89 (1H, d, J = 12.0 Hz, Ha-7), 4.67 (1H, d, J = 12.0 Hz, Hb-7). So that, the NMR data of 3-5 were compared with the corresponding data, reported for 2-phenylethyl β-rutinoside, [12] 2phenylethyl β-primeveroside, [12] hydrangeifolin, [13] respectively, and found to match well. Compounds 6-8 were identified as tortoside A [14] , pinoresinol-4ʹʹ-Oβ-D-glucopyranoside [15] , icariside B2 [16] by comparing their NMR data with the corresponding reported data and further confirmed by the ESI-MS, HSQC and HMBC spectra.…”

“…ESI-MS: m/z 417 [M+H] + C19H28O10. Hydrangeifolin I (5): [13] Colorlessamorphous powder; ESI-MS: m/z 439 [M+Na] + C19H28O10. Tortoside A (6): [14] Colorless amorphous powder.…”

Immunopotentiation of Caffeoyl Glycoside from Picrorhiza scrophulariiflora on activation and cytokines secretion of immunocyte in vitro

“…1. And its identity was determined by comparison of its spectral data with those reported in the literature [24]. The concentration of bacterial endotoxins (LPS) in the sample solution (125 mg/L) is 0.062 EU/mL assayed by chromogenic tachypleus amebocyte lysate Endpoint Kit (Chinese Horseshoe Crab Reagent Manufactory Co., Ltd., Xiamen, China) with a standard curve from 0.01 EU/mL to 0.1 EU/mL [25].…”
