ABSTRACT

Objective: To study the chemical constituents contained in the ethanol extracts from the roots of Chloranthus multistachys. Methods: Twelve compounds were separated from the roots of C. multistachys and their structures were identified by using various chromatographic techniques. Results: The structures of the 12 lindenane-type sesquiterpene dimmers from the chloroform and ethyl acetate extract in the roots of C. multistachys were identified on the basis of physicochemical properties and spectral data as 9-O-β-glucopyranosylcycloshizukaol A (1), cycloshizukaol A (2), shizukaol B (3), shizukaol C (4), shizukaol D (5), shizukaol F (6), shizukaol G (7), chloramultiol B (8), sarcandrolide B (9), sarglabolide I (10), 8-O-methyltianmushanol (11), and henriol B (12). Conclusion: Compounds 1, 7, and 9-12 are isolated from the roots C. multistachys for the first time and compounds 9 and 10 are obtained from the plants of Chloranthus Sw. for the first time.

ABSTRACT

To investigate the chemical constituents from the shoots of Chloranthus multistachys.All compounds wereisolated by using a combination of various chromatographic techniques including silica gel, ODS, Sephadex LH-20, reversed-phase HPLC, and other methods.Their structures were elucidated by the nuclear magnetic resonance (NMR), mass spectrometry, and other modernspectroscopies.As a result, 19 compounds were isolated from the shoots of C.multistachys and identified as zederoneepoxide(1), chlomultin C(2), curcolonol(3), sarcaglaboside A(4), zedoarofuran(5), (1E,4Z)-8-hydroxy-6-oxogermacra-1(10), 4,7(11)-trieno-12,8-lactone(6), chloranoside A(7), istanbulin A(8), (8α)-6,8-dihydroxycadina-7(11),10(15)-dien-12-oicacid-γ-lactone(9), codonolactone(10), lasianthuslactone A(11), 12,15-epoxy-5αH,9βH-labda-8(17),13-dien-19-oicacid(12), 12R,15-dihydroxylabda-8(17),13E-dien-19-oicacid(13), N-transcinnamoyltyramine(14), trans-N-p-coumaroyltyramine(15), dibutyl phthalate (16), flavokawain A(17), bergenin(18), and enedione(19).Compounds 1, 2, 4, 7-10, 12-19 were isolated from C.multistachys for the first time and compounds 14-19 were obtained from the genus Chloranthus for the first time.
