Source of material

Leaves and aerial parts of Senecio adenophyllus Meyen & Walp. collected at Socaire in Northern Chile ( 23° 36′ 40 s S; 67° 50′ 33 s W, 3230 m above sea level) were chopped and exhaustively extracted with EtOH:H2O (1:1, 10 L) during 1 week at room temperature. The alcoholic solution was filtered, evaporated under reduced pressure and freeze– dried to obtain a viscous mass of dark green extract. This residue (240 g) was suspended in 5 L methanol:water (1:9) and partitioned in succession with 5 L × 2 of n-hexane, 5 L × 2 of dichloromethane, 5 L × 2 of ethyl acetate and 5 L × 2 of n-butanol. After removal of the solvent in vacuo, the following residues were sequentially obtained: n-hexane-soluble (HF, 5 g), dichloromethane-soluble (DF, 15 g), ethyl acetate-soluble (EAF, 110 g), butanol-soluble (BF, 12 g), and finally residual water-soluble fraction (RWF, 70 g). A sample of EAF was separated by successive column chromatography over silica gel using n-hexane and EtOAc gradient with increasing amounts of EtOAc. Subsequent elution with n-hexane and EtOAc (7:3) gave a solid, which was then crystallized from acetone to afford needle-shaped crystals of the title compound; mp 161 °C. The crystals obtained were of low quality.

Experimental details

H atoms were located in the difference Fourier map, but refined with fixed individual displacement parameters, using a riding mode with C—H distances of 0.93 Å (for aromatic rings), C—H distances 0.97 Å, (for CH2), 0.96 Å (for CH3), with Uiso(H) values of 1.2Ueq(C) (for CH in aromatic and CH2), and 1.5Ueq(C) (for methyl group), O—H distances are 0.82 Å with Uiso(H) values of 1.5Ueq(O).

Discussion

The genus Senecio is the largest and most complex genus in the Asteraceae and include more than 1500 species with a worldwide distribution [1]. Aerial parts of several species of Senecio natives of the north of Chile are widely employed in the folk medicine as remedy for the altitudinal sickness [2], [3], [4]. In a continuation of a phytochemical research on Senecio species, which grow on the western flank of the Andes in northern Chile (ca 4000 m) [5], [6], [7], [8], we report the isolation of a new eremophylane sesquiterpenoid from Senecio adenophyllus Meyen & Walp. The title compound displayed spectral properties that are similar to those eremophylane sesquiterpenoids isolated from genus Cremanthodium, Ligularia and Senecio [1], [9], [10], [11], [12]. In order to ascertain the structure and secure the assignment of the stereochemistry of the title compound a single crystal structure determination was performed. Unfortunately, the absolute configuration was not determined by this method.

The structure consists of a sesquiterpenoid with an eremophilane skeleton. The methyl groups at C4 and C5 are equatorial and axial respectively. The hydroxyl group at C1 is α and equatorial oriented. The cyclohexene and cyclohexane rings are in a half-boat and chair conformation, respectively [QT = 0.4937(3) Å, φ2 = 268.66(5)°, θ = 124.03(2)°; QT = 0.547(3) Å, φ2 = 232.43(4)°, θ = 177.32°] [13]. The molecular conformation is stabilized by one strong intramolecular O—H⋯O hydrogen-bond (O3⋯O1 = 2.7344(1) Å, O3—H3⋯O1 = 135°) with graph-set motif S(6). In the crystal, molecules are linked by O—H⋯O, hydrogen-bonding interactions (O2⋯O3i = 2.8479(1) Å, O2—H2⋯O3i = 165°, symmetry code i = 1/2 + x, 1/2 − y, 1 − z) forming a chain structure along [100] direction with graph-set motif C(9) [14].
