ABSTRACT

Eight sesquiterpenes were isolated and purified from the ethanol extract of Chloranthus henryi by column chromatographies over silica gel, ODS and Sephadex LH-20,and preparative HPLC. Their chemical structures were established by spectral data and physiochemical properties as(1S,6S,8S,10R)-8-ethoxy-10-methoxychlomultin C(1),tianmushanol(2),multistalide A(3),myrrhterpenoid N(4),1α,9α-dihydroxy-8,12-expoxy-eudesma-4,7,11-trien-6-one(5),4β,10α-aromadendranediol(6),oplopanone(7),10α-hydroxycadinan-4-en-3-one(8). Among them, compound(1) was a new compound, and compounds 2-8 were isolated from Chloranthus henryi for the first time.

ABSTRACT

An ethanol extract of Chloranthus henryi (Chloranthaceae) was subjected to various chromatographic procedures including silica gel column chromatography, MCI column chromatography, Sephadex LH-20 column chromatography, and preparative HPLC. Five purified sesquiterpenes analyzed by spectroscopic analyses (MS, IR, NMR) and single crystal X-ray diffraction were elucidated as (1S,6S,8R)-8-ethoxychlomultin C (1a), (1R,6R,8S)-8-ethoxychlomultin C (1b), (+)-phaeocaulin D (2), atractylenolide Ⅰ (3), and 8-β-ethoxyasterolid (4). Compounds 1a and 1b were a new pair of sesquiterpene enantiomers and compounds 2-4 were isolated from this plant for the first time. Compounds 1a, 1b, 2 and 3 increased cell viability in H2O2-treated PC12 cells from (43.41 ± 1.59) % to (61.71 ± 7.56) %, (66.05 ± 5.61) %, (74.34 ± 3.32) % and (69.58 ± 5.02) % at 10 μmol·L-1, respectively.

ABSTRACT

Objective: To study the antitumor constituents from Chloranthus fortunei. Methods: Various chromatographic techniques and spectroscopic methods were applied to investigate the chemical constituents from C. fortunei, and some of the compounds were screened for their antitumor activities by MTT method. Results: Sixteen compounds were obtained from the whole plants of C. fortunei and identified as rosmarinic acid (1), 2’-hydroxy-4,3’,4’,6’-tetramethoxychalcone (2), flavokawain A (3), cycloshizukaol A (4), atractylenolide III (5), 4β-hydroxy-8,12-epoxyeudesma-7,11-diene-1,6-dione (6), (8α)-6,8-dihydroxycadina-7 (11),10 (15)-dien-12-oic acid γ-lactone (7), curcolonol (8), 11-hydroxyldrim-8,12-en-14-oic acid (9), friedelin (10), isovanillic acid (11), 6β-hydroxystigmast-4-en-3-one (12), 3,4-dihydroxybenzoic acid (13), shikimic acid (14), scopolin (15) and N-acetyltyramine 1-O-β-D-glucoside (16). Compounds 4 and 5 showed weak cytotoxicity with IC50 ranged from 46 to 85 μmol/L. Conclusion: Compounds 2, 10, 11, and 13-15 are obtained from the genus Chloranthus for the first time and compounds 1-3 and 6-16 are isolated from C. fortunei for the first time. Some sesquiterpenoids from C. fortunei exhibited weak antitumor activities.

ABSTRACT

The chemical constituents of the aerial parts of Lespedeza cuneata (Dum. Cour.) G. Don were investigated using chromatographic techniques, such as silica gel, reversed phase MPLC and preparative HPLC. Five compounds were isolated and their structures were elucidated by spectroscopic data and physicochemical properties, which were identified as 7-O-glucosyllaburnetin (1), kaempferol-3-O-β-D-galactopyranoside (2), kaempferol-3-O-α-L-rhamnoside (3), vitexin (4), and isovitexin (5). Among those, compound 1 is a new compound, compounds 2-3 were isolated from this plant for the first time. Compounds 1-5 were tested for their anti-ulcerative colitis activity by dual luciferase report gene assay targeting xbp1. Compared with control group, compound 1 showed a certain activity on activating the transcription of xbp1, with its relative activating ratio being 1.80 times.

ABSTRACT

Five triterpene saponins were isolated from the aqueous extract of the leaves of Panax notoginseng (Burk.) F.H.Chen via various chromatographic approaches, including HPD-100 macroporous resin, silica gel, reverse phase C18 and so on. Spectroscopic and chemical methods were used to elucidated their structures, which were determined to be 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-12β,23(R)-epoxydammara-24-ene-3β,6α,20(S)-triol 20-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (1), 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-12β,23(R)-epoxydammara-24-ene-3β,6α,20(S)-triol 20-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (2), notoginsenoside FP2 (3), gypenoside Ⅸ (4), ginsenoside Rg1 (5). Compounds 1 and 2 are new compounds and named as notoginsenoside Fh8 and notoginsenoside Fh9.
