General Experimental Procedures. Optical rotations were recorded on a Perkin-Elmer 241 polarimeter. IR and UV spectra were performed on MIDAC M-series FTIR and Shimadzu UV-1201 spectrophotometers,
respectively. NMR spectra were obtained on JEOL Eclipse 500, Varian
Inova 400, and Varian Unity 400 spectrometers. Mass spectra were obtained on a JEOL-JMS-HX-110 instrument.
Chemical shifts are given in δ (ppm), and coupling constants (J) are reported in Hz. HPLC was performed using Shimadzu LC-8A pumps coupled with a Varian Dynamax preparative phenyl column (250 × 21.4 mm) and Shimadzu LC-10A pumps coupled with a Varian Dynamax semipreparative column (250 × 10 mm).
Both HPLC instruments employed a Shimadzu SPD-M10A diode
array detector.
Antiproliferative Bioassay. The A2780 ovarian cancer cell line assay was performed at Virginia Polytechnic Institute and State University as previously reported.7 The A2780 cell line is a drugsensitive ovarian cancer cell line.8
Plant Material. The plant sample of Cordyla madagascariensis R.Vig. ssp. madagascariensis was collected on March 30, 2004, by R.R. et al.in Antsiranana, Madagascar, in the vicinity of Mahavanoma .
It was assigned collector number R. Rakotondrajaona 319,
and it was determined by R.R. The specimens were from a tree 15 m high
and diameter at chest height of 40 cm.Voucher specimens have been deposited at herbaria of the Centre National d’Application des Recherches Pharmaceutiques, Madagascar (CNARP); the Parc Botanique et Zoologique de Tsimbazaza, Madagascar (TAN); the Missouri Botanical Garden, St.
Louis, Missouri (MO); and the Muséum National d’Histoires Naturelles,
Paris, France (P).
