(Received 7 October 2010; accepted 10 October 2010; online 20 October 2010)

The title compound, systematic name 9-isopropyl­idene-2,6-dimethyl-11-oxatricyclo­[6.2.1.01,5]undec-6-en-8-ol, C15H22O2, which crystallizes with two mol­ecules of similar conformation in the asymmetric unit, features three fused rings, two of which are five-membered and the third six-membered. Of the two five-membered rings, the one with an O atom has a distinct envelope shape (with the O atom representing the flap). The six-membered ring is also envelope-shaped as it shares a common O atom with the five-membered ring. In the crystal, the two independent mol­ecules are linked by a pair of O—H⋯O hydrogen bonds, generating a dimer.

Supporting information


Comment top

Zingerberaceae is a herbaceous plant found in tropical forests that comprises of 52 genera with 1500 species. Most species are found in the South East Asian region. Curcuma zedoaria, also known as white turmeric, is a species that is a rich source of terpenoids.

Curcumenol, isolated from Globba malaccensis Ridl, belongs to the monoclinic, space group C2, with a 16.8467 (4), b 7.6799 (2), c 11.8613 (10) Å and β 115.997 (1) °. This modification is less dense, as noted from its calculated density of 1.28 (Muangsin et al., 2004). The present modification (I), (Fig. 1) shows nearly identical bond dimensions in the two independent molecules. The two molecules form a dimer in the crystal, being linked by two O—H···O hydrogen bonds.

Experimental top

The rhizome of Curcuma zedoaria was collected from Tawangmangu, Indonesia.

Dried rhizomes (1 kg) were powdered and extracted three times with n-hexane and after this, with dichloromethane, ethylacetate, and methanol. The extracts were concentrated under reduced pressure given several fractions.

The n-hexane crude extract (20 g) was subjected to column chromatography over silica gel 60(0.063–0.200 mm, 70–230 mesh ASTM) eluted with a mixture of n-hexane: ethyl acetate with increasing polarity. Separation by TLC gave 21 fractions.

Fraction 10 (1.41 g) was chromatographed over silica gel (0.040–0.063 mm, mesh 230–400 ASTM) eluted with a gradient solvent system of n-hexane: ethyl aceate to give 5 fractions. The second fraction was further purified by high performance thin layerchromatography and using petroleum ether: ethyl acetate: acidified methanol in a 85:14:1 ratio as the developing solvent. Slow evaporation of the solvent gave (I) as colorless prisms.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 to 0.98 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 to 1.5U(C).

In the absence of heavy atoms, 2923 Friedel pairs were merged.

The hydroxy H-atoms were located in a difference Fourier map, and were refined without restraints; their Uiso values were freely refined.

The absolute configuration was assumed to be that of the C2 modification.
