- Three new polyphenolic acids from the leaves of Eucalyptus citriodora with antivirus activity
-
Six polyphenolic acids (1-6), including the three new compounds citriodolic acids A, B, and C (1-3), were isolated from the leaves of Eucalyptus citriodora. Their structures were elucidated by spectroscopic methods including one dimensional (1D)- and 2D-NMR, high-resolution electrospray ionization (HR-ESI)-MS, and circular dichroism (CD). The potential antivirus activity against respiratory syncytial virus (RSV) of all the isolated compounds was evaluated.

- Studies on the Constituents of the Plants of Illicium Species. II. Structures of Phenolic Components
-
Ten phenolic compounds were isolated from leaves or timber of Illicaceous plants, Illicium tashiroi MAXIM., I. arborescens HAYATA, and I. anisatum L., and their structures were determined 1-10 by spectroscopic and synthetic studies.Of the ten, 4-allyl-5-(3-methylbut-2-enyloxy)-1,2-methylenedioxybenzene (7), 4-allyl-2-methoxy-6-(3-methyl-2-butenyl)phenol (9), and 4-allyl-2,6-dimethoxy-3-(3-methyl-2-butenyl)phenol (10) are new compounds.Keywords - phenolic compound; Illicium tashiroi; Illicium arborescens; Illicium anisatum; Illiciaceae; (13)C-NMR
