(Received 15 October 2010; accepted 10 November 2010; online 17 November 2010)

The title compound, C30H52O5·2H2O, was degraded from pseudoginsenoside F11 which was extracted and seperated from Panax quinquefolium saponin. The three six-membered rings are in chair conformations. The five-membered ring is in an envelope conformation and the tetra­hydro­furan ring has a conformation inter­mediate between half-chair and envelope. In the crystal, inter­molecular O—H⋯O hydrogen bonds link mol­ecules into a three-dimensional network. Intra­molecular O—H⋯O hydrogen bonds also occur.

Comment top

Both Panax ginseng and Panax quinquefolium, belonging to Araliaceae, are well known traditional medicinal herbs. They are used as tonics and for the treatment for diseases, such as tumor and myocardial ischemia. Panax ginseng contains a number of saponins, namely ginsenoside and an oleanolic acid-type saponin in addition to the major protopanaxadiol and protopanaxatriol-type saponins (Shibata et al.,1985). Panax quinquefolium contains an ocotillol-type (20S, 24R-epoxyside) saponin with high anti-tumor activity (Takano et al.,1999), as well as oleanolic acid-type saponin, protopanaxadiol and protopanaxatriol-type saponins. (3R,6R,12R,20S,24S)-20,24-epoxy-dammarane-3,6,12,25-tetraol is found to possess cardioprotective effects on myocardial injury induced by isoproterenol in rats (Yu et al.,2007). As part of our ongoing investigation of ocotillol-type compounds and their cardioprotective effect on myocardial injury, we report here the crystal structure of the title compound, (I).

The molecular structure of (I) is shown in Fig. 1. In the molecule, all bond lengths and angles are within normal ranges (Shi et al.,1992; Iljin et al.,1982). The six-membered rings A(C3/C4/C5/C6/C7/C8), B(C7/C8/C10/C11/C12/C14), and C(C12/C14/C15/C16/C17/C18) are in chair conformations that depart significantly from ideal geometry to accommodate for intramolecular non-bonded 1,3-diaxial interactions involving the methyl groups. The five-membered ring D(C13/C14/C15/C16/C17) has an envelope form with C18 as the out-of-plane atom. The tetrahydrofuran ring has a conformation intermediate between half-chair and envelope forms. In the crystal structure intermolecular O-H···O hydrogen bonds link molecules into a three-dimensional network.

Experimental top

Pseudoginsenoside F11 was extracted and seperated from Panax quinquefolium saponin. (3R,6R,12R,20S,24S)-20,24-epoxy-dammarane-3,6,12,25-tetraol was degraded from Pseudoginsenoside F11 with sodium in glycerine and seperated by flash chromatography. Finally, the crystals were dried at room temperature. Single crystals of compound (I) suitable for X-ray measurements were obtained by recrystallization from ethyl acetate at room temperature.

Refinement top

H atoms bonded to C atoms were fixed geometrically and allowed to ride on their attached atoms, with C—H distances in the range 0.96–0.98 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(Cmethyl). The H atoms bonded to hydroxy O atoms were included with O-H = 0.82Å and Uiso(H) = 1.5Ueq(O) and water H atoms were included in 'as-found' positions with Uiso(H) = 0.12Å3. In the absence of anomlaous dispersion effects Friedel pairs were merged. The absolute configuration is based on unchanging stereochemical centers in the synthesis.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
