illicium tsangii/hepatitis

Two new compounds, 2S-hydroxyl-jiadifenolide (1) and jiadifenlactone acid (2), and eight known compounds were isolated from the fruits of Illicium jiadifengpi. Their structures were analysed using several spectroscopic techniques, including 1D-, 2D-NMR and HR-ESI-MS experiments. The anti-hepatitis B

Two new seco-prezizaane-type sesquiterpenes, 3,4-dehydroneomajucin (1) and 1,2,3,4-tetradehydroneomajucin (2), were isolated from the fruits of Illicium jiadifengpi. The structure of these compounds was determined using 1D and 2D NMR and ESI-MS. The isolates were evaluated for their anti-hepatitis B

Two new lignans, dihydrodehydrodiconiferyl alcohol 9-O-β-D-(3″-O-acetyl)-xylopyranoside (1) and threo-4,9,9'-trihydroxy-3,3'-dimethoxy-8-O-4'-neolignan 7-O-α-rhamnopyranoside (2) were isolated from Illicium henryi, together with ten known compounds, 3-12. Their structures were elucidated by

Five new sesquiterpene lactones, henrylactones A-E ( 1- 5), together with ten known compounds: cycloparvifloralone ( 6), tashironin ( 7), tashironin A ( 8), neoanisatin ( 9), anisatin ( 10), anislactone B ( 11), 7- O-acetylanislactone B ( 12), merrillianolide ( 13), cyclomerrillianolide ( 14) and
