Chemical Constituents from the Roots of Polygala arillata and Their Anti-Inflammatory Activities

A new compound, named arillatanoside E, which was elucidated as 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl-(1 - 3)-β-D-xylopyranosyl-(1 - 4)-α-L-rhamnopyranosyl-(1 - 2)-(4-O-acetyl)-β-D-fucopyranosyl ester, along with 11 known compounds was isolated from the ethanolic extract of the roots of Polygala arillata. The 11 known compounds were identified as oleanolic acid (2), 3′-E-3,4,5-trimethoxy cinnamoyl-6-benzoyl sucrose (3), trans-ferulic acid (4), trans-feruloyl-glucoside (5), feruloyl-glucoside (6), 2,4,6-trimethoxy-1-O-β-D-glycoside (7), 3-methoxy-4-hydroxybenzoic acid (8), monopentadecanoin (9), sinapic acid (10), p-hydroxybenzaldehyde (11), and palmitic acid (12). Among them, seven isolated compounds 1, 2, 4, 5, 7, 8, and 10 exhibited little cytotoxic activity on macrophage RAW 264.7 cells. Then, the inhibitory effects of 7 isolates on nitric oxide (NO) production in lipopolysaccharide-activated macrophages were evaluated. As a result, 3 compounds have significant anti-inflammatory activity, and they were arillatanoside E (1), oleanolic acid (2), and 2,4,6-trimethoxy-1-O-β-D-glycoside (7).

Melanogenesis-Inhibitory and Cytotoxic Activities of Triterpene Glycoside Constituents from the Bark of Albizia procera

Five oleanane-type triterpene glycosides including three new ones, proceraosides E-G (1-3), were isolated from a MeOH-soluble extract of Albizia procera bark. The structures of 1-3 were determined by use of NMR spectra, HRESIMS, and chemical methods. Compounds 1-5 exhibited inhibitory activities against the proliferation of the A549, SKBR3, AZ521, and HL60 human cancer cell lines (IC50 0.28-1.8 μM). Additionally, the apoptosis-inducing activity of compound 2 was evaluated by Hoechst 33342 staining and flow cytometry, while the effects of 2 on the activation of caspases-9, -8, and -3 in HL60 cells were revealed by Western blot analysis.

Acylated oleanane-type triterpene saponins from the flowers of Bellis perennis show anti-proliferative activities against human digestive tract carcinoma cell lines

Seven oleanane-type triterpene saponin bisdesmosides, perennisaponins N–T (1–7), were newly isolated from a methanol extract of daisy, the flowers of Bellis perennis L. (Asteraceae). The structures were determined based on chemical and physicochemical data and confirmed using previously isolated related compounds as references. The isolates, including 13 previously reported perennisaponins A–M (8–20), exhibited anti-proliferative activities against human digestive tract carcinoma HSC-2, HSC-4, and MKN-45 cells. Among them, perennisaponin O (2, IC50?=?11.2, 14.3, and 6.9?μM, respectively) showed relatively strong activities. The mechanism of action of 2 against HSC-2 was found to involve apoptotic cell death.

A new triterpenoid bidesmoside (leptocarposide) possessing an acyl group in their glycosidic moiety (1), together with the known luteolin-8-C-glucoside (2) and 1-O-β-D-glucopyranosyl-(2S,3R,8E)-2-[(R)-2-hydroxypalmitoylamino]-8- octadecen-1,3- diol (3) was isolated from the n-butanol-soluble fraction of whole plant of Ludwigia leptocarpa (Nutt) Hara (Onagraceae). Structure of compound 1 has been assigned on the basis of spectroscopic data (1H and 13C NMR, 1H-1H COSY, HSQC, HMBC, and ROESY), mass spectrometry, and by comparison with the literature. This compound was further screened for its potential antioxidant properties by using the radical scavenging assay model 2,2-diphenyl-1-picrylhydrazyl and reveals non-potent antioxidant activities, while compound 2 shows SC50 of 0,038 mM.
