Abstract top

The title compound, C29H48O, is a triterpenoid isolated from Adiantum incisum forssk. In the crystal structure, the asymmetric unit contains two independent molecules which are not significantly different. Each molecule contains four six-membered rings, all adopting chair conformations, and a five-membered ring in an envelope conformation. In the molecular structure, non-classical intramolecular C-H...O hydrogen bonds are observed.

Comment top

Triterpenoids are an important class of natural products and are recognized for their ethnobotanical nature i.e. analgesic, anti-microbial and anti-inflammatory (Brahmachari et al., 2003; Bresciani et al., 2003; Reddy et al., 2001). Adiantum incisum forssk, syn. Adiantum caudatum L., a fern, used in ayurvedic medicines, is well known for its use against diabetes and skin diseases (Nadkarni & Nadkarni, 1982). During its phytochemical investigations, the title compound (I), along with other compounds (Hussain et al., 2007, 2008), was isolated and its crystal structure is hereby reported; it has been reported as one of the constituents of Adiantum pedatum (Ageta & Iwata, 1966).

The asymmetric unit of (I) contains two independent molecules A and B, presented in Figs. 1 and 2, respectively. There are no significant differences in the molecular dimensions of the two molecules. Both molecules contain four six-membered rings, all adopting chair conformations and a five-membered ring adopting envelope conformation with atoms C18 and C48, 0.656 (9) and 0.684 (9) Å out of the planes formed by the remaining ring atoms, C17/C19/C20/C21 and C47/C49/C50/C51, respectively. The acetyl groups bonded to the five membered rings show intramolecular H-bonding interactions, C20—H20···O30 and C50—H50···O60 (Table 1).

Experimental top

Adiantum incisum forssk was collected from Murree hills, Pakistan, during September 2003. After shade drying, pinnae were separated from rachis. The dried rhizomes, stipes and rachis (2.9 kg) were soaked in ethanol (20 L) for fifteen days and filtered. The filtrate was concentrated at 313 K under reduced pressure to give 51.33 g of ethanolic extract, which was subjected to silica-gel column chromatography eluting gradient solvent system hexane-chloroform-methanol. More than 300 fractions were monitored by thin layer chromatography and combined to give 38 main fractions. Fraction 5 was further purified by silica-gel column chromatography with hexane-chloroform (10:1) and preparative TLC with dichloromethane and petroleum ether (2:3) to give the pure title compound (I). X-ray quality crystals were grown from a solution of hexane-chloroform (9:1) at room temperature.

Refinement top

H atoms were included in the refinements at geometrically idealized positions with C—H distances 0.95 - 1.00 Å, and with Uiso(H) = 1.2Ueq(C), allowing for free rotation of the methyl groups. The final difference map was free of any chemically significant features. In the absence of significant anomalous scattering effects, an absolute structure could not be established in this analysis and therefore, Friedel pairs were merged.

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.
