The title dammarane tritepene, 3α,20(S)-dihy­droxy­dammar-24-ene, which crystallized out in a hydrated form, C30H52O2.1.075H2O, was isolated from the Aglaia eximia bark. The three cyclo­hexane rings adopt chair conformations. The cyclo­pentane has an envelope conformation with the quaternary C at position 14 as the flap atom with the maximum deviation of 0.288 (2) Å. The methyl­heptene side chain is disordered over two positions with 0.505 (1):0.495 (1) site occupancies and is axially attached with an (+)-syn-clinal conformation. The hydroxyl group at position 3 of dammarane is in a different conformation to the corresponding hydroxyl in Dammarenediol II. In the crystal, the dammarane and water mol­ecules are linked by ODammarane—H⋯Owater and Owater—H⋯ODammarane hydrogen bonds into a three-dimensional network.

Comment top

Aglaia genus plants belonging to the Mahogany family have been known as a good source of organic acids, sesquiterpenes, diterpenes and triterpenes (Chairgulprasert et al., 2006; Qiu et al., 2001; Roux et al., 1998; Yodsaoue et al., 2012). Many of the various terpenenoids from this genus possess interesting biological properties such as anti-inflammatory (Yodsaoue et al., 2012), cytotoxic (Zhang et al., 2010) and insecticidal (Greger et al., 2001) activities. The title compound (I), 3-epi-Dammarenediol II or 3α,20(S)-dihydroxydammar-24-ene, was previously isolated from Trattinnickia burserifolia (Lima et al., 2004). However it is now isolated for the first time from Aglaia eximia, a plant which was used as a traditional medicine for the treatment of malaria in Indonesia (Grosvenor et al., 1995). Herein the crystal structure of (I) is reported.

Compound (I) has a dammarane nucleus and crystallized in a hydrated form, C30H52O2.1.075(H2O) (Fig. 1). Two of the water molecules, O1W and O2W, have half occupancies and lie on two-fold axis, the other H of each water molecule was generated by a symmetry operation, -x, -y, z, whereas the third water molecule, O3W, has 0.075 occupancy. The molecule of dammarane has four fused rings and all rings are in trans-fused conformation. The three cyclohexane rings are in standard chair conformations. The cyclopentane (C13–C17) adopts an envelope conformation with the puckered C14 atom having the maximum deviation of 0.288 (2) Å, Q = 0.457 (3) Å and θ = 220.1 (3)° (Cremer & Pople, 1975). The hydroxyl group at atom C3 is axially attached which is different from the corresponding hydroxyl group in Dammarenediol II (Asakawa et al., 1977). The methylheptene side chain is disordered over two positions; the major component and the minor component A (Fig. 1), with the refined site-occupancy ratio of 0.505 (1)/0.495 (1) and is axially attached at atom C20 with the torsion angle of C17–C20–C22–C23 = 58.83 (3)°, indicating an (+)-syn-clinal conformation with respect to the cyclopentane ring (Fig. 1). The bond distances in (I) are within normal ranges (Allen et al., 1987) and comparable to a related structure (Qiu et al., 2001).

The crystal packing of (I) is consolidated by intermolecular ODammarane—H···Owater and Owater—H···ODammarane hydrogen bonds (Table 1). The molecules of 3-epi-Dammarenediol II and water molecules are linked by O—H···O hydrogen bonds into a three dimensional network (Fig. 2).

Experimental top

The dried and milled bark of A. eximia (3 kg) which was collected from Bogor Botanical Garden, West Java, Indonesia, was extracted successively by n-hexane, ethyl acetate and methanol at room temperature. The ethyl acetate extract (300 g) was subjected to vacuum chromatography on silica gel G 60 by using a step gradient of n-hexane-ethyl acetate methanol. The fraction eluted by n-hexane/ethyl acetate (3:2) was further separated by column chromatography on silica gel (chloroform: methanol; 9.5:0.5 v/v) to give a colorless solid (63 mg) of the title compound. Colorless needle-shaped single crystals of the title compound suitable for X-ray structure determination were recrystallized from ethyl acetate at room temperature after several days.

Refinement top

One of the water molecules, O3W, was refined isotropically. H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(O—H) = 0.83-0.84 Å, d(C—H) = 1.00 Å for cyclic CH, 0.95 for CH, 0.99 for CH2 and 0.98 Å for CH3 atoms. The Uiso values were constrained to be 1.2Ueq of the carrier atom for all H atoms. A rotating group model was used for the methyl groups. A total of 3923 Friedel pairs were merged before final refinement. The methylheptene side chain is disordered over two sites with refined site occupancies of 0.505 (1) and 0.495 (1). The same Uij parameters were used for atom pairs C23/C24, C26/C27 and C26A/C27A. A number of reflections were omitted from the final refinement owing to poor agreement.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
