ABSTRACT
Illicium henryi Diels is a medicinal and aromatic plant native to China with Chinese name Mancao or Hondu-hui.The name of Mancao was first recorded in the"Classic of Mountains and Rivers"and the earliest documented medicinal function of this plant was found in"Shen Nong′s herbal classic".Its botanical origin includes Illicium lanceolatum A.C. Smith and Illicium henryi Diels while Miscanthus sinensis Anderss(Gramineae)and Tripterygium wilfordii Hook.f. (Celastraceae)were recorded as Mancao by mistake.Mancao is mainly distributed in Henan,Hebei,Sichuan,Zhejiang and Fu-jian Province.All those plants are toxic.In this paper,the name,habitats,origins,the characteristics and effects of Illicium lanceolatum A.C.Smith and Illicium henryi Diels were investigated to correct the origin of the textural records and provide a reference for future research,development and utilization of the medical resources.
ABSTRACT
AIM@#To study the chemical constituents of the fruits of Illicium henryi.@*METHOD@#Chromatographic separations on silica gel, Sephadex LH-20 gel and MCI gel were used to isolate the compounds. The structures were elucidated based on extensive spectroscopic data analyses.@*RESULTS@#Seven compounds were obtained and their structures were identified as 10-benzoyl-cycloparvifloralone (1), cycloparvifloralone (2), 2α-hydroxycycloparviforalone (3), henrylactone B (4), merrillianone (5), henrylactone C (6) and 7, 14-ortholactone- 3-hydroxyfloridanolide (7).@*CONCLUSION@#Compound 1 is a new sesquiterpene lactone. The tested compounds showed weak anti-HBV activities on HBV surface antigen (HBsAg) secretion and HBV e antigen (HBeAg) secretion using Hep G2.2.15 cell line.
