Source of material
The whole plants of Pyrrosia petiolosa (Christ) Ching were collected in March 2017 at Longli County, Guizhou Province, China. The air-dried plants (20 kg) were crushed and extracted with 95% EtOH at room temperature. The solvent was removed under reduced pressure to obtain the residue (2 kg), which was then suspended in 2 L of water, and extracted successively with petroleum ether, dichloromethane, ethyl acetate, and n-butanol. The petroleum ether fraction (35 g) was subjected to silica gel chromatography repeatedly to yield the title compound. The data used in this study was collected from its colorless block-shaped crystal in EtOAc/MeOH (1:1).
Experimental details
The software APEX 2 [1] was employed for data collection at 205 K. Using Olex2 [2], the structure was solved with the ShelXT [3] structure solution program using Intrinsic Phasing. Its structure was refined with the ShelXL refinement package [4]. Hydrogen atoms were positioned geometrically, with C—H distance of 0.94 Å for aromatic CH, 0.97 Å for CH3, and 0.83 Å for OH. The Uiso values were fixed at 1.2 times of all the C(H) group, and 1.5 times of CH3 and OH groups.
Comment
The title compound, with trivial names: barbatic acid or barbatinic acid, belongs to depside derivatives, the natural products commonly present in lichen [4], [5], [6], [7]. Depside derivatives have been reported to exhibit various biological effects including antimicrobial, anti-hepatic fibrosis, anti-diabetic, and antiviral activities [8], [9], [10]. Some crystal structures of depside derivatives have been reported before [10], [11], [12]. The bond lengths and angles of the title compound are in normal ranges. The methoxy group at C2 is almost coplaner with the benzene ring (C2, C3, C4, C5, C6, C7) with the torsion angle of 1.8(2)°, defined as plane I. The carboxyl group at C15 is twisted from the other benzene ring (C11, C12, C13, C15, C16 and C17) by 5.3(4)°, defined as plane II. The ester group is defined as plane III. For the steric interaction with the adjacent groups, plane III deviates from plane I with a dihedral angle of 13.9(3)°. In addition to two intramolecular hydrogen bonds, intermolecular hydrogen bonds are observed, which link the molecules of the compound into chains. Moreover, p-p interactions are observed with distances of 3.636 Å and 3.453 Å, respectively.
