The chemical constituents of the stems of Schisandra sphenanthera are described for the first time. This investigation has resulted in the isolation of a new phenolic glycoside (1), along with seven known compounds....The chemical constituents of the stems of Schisandra sphenanthera are described for the first time. This investigation has resulted in the isolation of a new phenolic glycoside (1), along with seven known compounds. The structure of 1 was assigned by using spectroscopic techniques, including 2D NMR spectra.展开更多
A new lipophilic monosaccharide, erigearide A (1), was isolated from the aerial parts of Erigeron annuus (Lima.) Pers. Its structure was elucidated by analysis of spectroscopic evidence.
Two new ent-kaurane diterpenoids, minheryins H (1) and I (2), were isolated from the leaves of Isodon henryi. Their structures were elucidated by means of spectroscopic analysis, including 2D NMR spectra.
A new phenylethanoid glycoside,seulponisidc(1) was isolated from the aerial parts of Isodon sculponeatus(Vaniot) Kudo, along with six known compounds martynoside(2),verbascoside(3),(+)-hydroxypinoresinol-8-...A new phenylethanoid glycoside,seulponisidc(1) was isolated from the aerial parts of Isodon sculponeatus(Vaniot) Kudo, along with six known compounds martynoside(2),verbascoside(3),(+)-hydroxypinoresinol-8-O- β-D-glucoside(4),cedrusin(5), 7-megastigmene-3S,5R,6R,7E,9S-tetrol(6) and 4-oxo- β-ionol- β-D-glucopyranoside(7).Their chemical structures were elucidated from physieochemical data and by acidic hydrolysis.展开更多
