Six new sesquiterpenes, 2,6(12),10-humulatrien-7β-ol-1-one (1), 2 α-acetoxy-5α-methoxy-enantio-caryophylla-8(15)-en-3-one (2), 2α-acetoxy-5α-hydroxy-enantio-caryophylla-8(15)-en-3-one (3), 2α-acetoxy-4β,5α-hydroxy-enantio-caryophylla-8(15)-en-3-one ( 4), 2α-acetoxy-4β,5β-hydroxy-enantio-caryophylla-8(15)-en-3-one (5), 2β-acetoxy-4-caryophyllen-8β-ol-3-one (6), and nineteen known compounds were isolated from the ethanol extract of Buddleja daviddi. The structures were elucidated by spectroscopic methods. Compounds 8-11, 14, 16, 17, and 20 showed significant immunosuppressive activities, and 8-11 and 14 were cytotoxic on HeLa and L929 cell lines.


Planta Medica | 2012

Lignans from Schisandra propinqua with inhibitory effects on lymphocyte proliferation.

Mei Na Jin; Zhi Yao; Yoshihisa Takaishi; Hong Quan Duan

Seven new dibenzocyclooctadiene lignans, named propinquain E-K, together with 11 known lignans were isolated from the ethanol extract of the roots of Schisandra propinqua subsp. sinensis. The structures of the new compounds were elucidated by spectroscopic methods, including ¹H- and ¹³C-NMR, 2D-NMR, HR ESI-MS, and CD spectra. Two dibenzocyclooctadienes revealed inhibitory effects on lymphocyte proliferation.
