Abstract:

On the basis of the investigation on natural product antitumor agents, a new diterpenoid named macrocalyxin J was isolated from the leaves of Rabdosia macrocalyx(Dunn) Hara by silica gel column chromatography. Based on IR, MS, 1H NMR, 13C NMR and 2D NMR spectroscopies, the structure of macrocalyxin J was determined as (1α,6β,11β,14α)-1,7∶6,20-diepoxy-6,11-dihydroxy-6,7-seco-ent-kaur-16-ene-7,15-dione-14-acetate. The antitumor activity of the compound was assayed by MTT method. Macrocalyxin J was shown to have a potency in vitro against the cultures of Hela cells.

Key words: Rabdosia macrocalyx, B-seco-ent-kaurene, Macrocalyxin J
