In the title compound, C13H12O3, the pyran ring adopts a half-chair conformation with a C atom deviating from the least-squares plane of the remaining ring atoms by 0.606 (2) Å. This plane and that of the benzene ring make a dihedral angle of 44.18 (6)°. In the crystal, molecules are linked through O—H⋯O hydrogen bonds into infinite chains along the b axis, and these chains are cross-linked by C—H⋯O hydrogen bonded into sheets lying parallel to the bc plane. The layers are further connected via C—H⋯π interactions to form a three-dimensional supramolecular structure.

Samples of the roots of G. ridleyi were collected from Post Brooke, Gua Musang, Kelantan, Malaysia. The roots were dried in an oven (323 K), ground and extracted using cool extraction. The extraction using three types of solvents i. e., hexane, chloroform and methanol gave three crude extracts. The chloroform crude extract (9.57 g) was separated using vacuum
(VLC). A mixture solvent of ethyl acetate and methanol as solvent gave 12 fractions. TLC profiles showed fractions 1–3 were identical. Therefore, these fractions has been selected for further separation using (CC) with solvents hexane and ethyl acetate; 178 vials were collected and vials 157–165 have been selected for preparative TLC (PTLC) using hexane:ethyl acetate (9:11). GRAB 6 (0.0617 g) with Rf 0.46 in solvent system hexane: ethyl acetate (5:5) was crystallized from a mixture of ethyl acetate and n-hexane (1:1) at room temperature.The C-bound hydrogen atoms were located in the calculated positions and refined in a riding mode with C—H distances of 0.95 (Csp2) and 1.000 (Csp3) Å. The O-bound H atom was found in a difference Fourier map and refined freely. For all hydrogen atoms, Uiso were set to 1.2Ueq(carrier atom). In the absence of significant
effects Friedel pairs were merged.The title compound was isolated from the roots of Goniothalamus ridleyi and found to be the same styrylpyrone isolated from the stem bark of Goniothalamus dolichocarpus (Goh et al., 1995). In agreement with the structures of similar molecules (Fun et al., 1995; Tuchinda et al., 2006), the pyran ring in the title molecule adopts a half-chair conformation with C9 displaced by 0.606 (2) Å from the plane of the remaining ring atoms (C10/C11/C12/C13/O3). This plane and the benzene ring make a dihedral angle of 44.18 (6)°. The crystal packing comprises three dimensional network formed by O—H···O, C—H···O and C—H···π interactions (Table 1, Fig. 2).

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. |

The title compound was isolated from the roots of Goniothalamus ridleyi and found to be the same styrylpyrone isolated from the stem bark of Goniothalamus dolichocarpus (Goh et al., 1995). In agreement with the structures of similar molecules (Fun et al., 1995; Tuchinda et al., 2006), the pyran ring in the title molecule adopts a half-chair conformation with C9 displaced by 0.606 (2) Å from the plane of the remaining ring atoms (C10/C11/C12/C13/O3). This plane and the benzene ring make a dihedral angle of 44.18 (6)°. The crystal packing comprises three dimensional network formed by O—H···O, C—H···O and C—H···π interactions (Table 1, Fig. 2).
