Examples
Embodiment 1
[0205] Ethyl acetate extract of S. tomentosa (LI / DD-H / 054A / 01): S. tomentosa flower heads (2.2kg) were used as the experimental extract and extracted with ethyl acetate (22L) at reflux temperature for 2 hours . The extract was filtered and the extraction of the spent material was repeated twice with ethyl acetate (2 x 13 L) under the same conditions. The combined extracts were fine filtered and concentrated in a rising film evaporator to obtain a residue (174g). Analysis by high performance liquid chromatography showed that the ethyl acetate extract contained 11% of 7-hydroxy-4,11(13)diketenone-12,6-lactone (7-hydroxyorcinone).
Embodiment 2
[0207] N-hexane extract of S. tomentosa (LI / DD-H / 054A / 02): Put S. tomentosa flower heads (1.0 kg) into a Soxhlet apparatus and extract with n-hexane (6 L) at reflux temperature for 4 hours, the extract was fine-filtered, and the spent material was extracted twice more with n-hexane (2x4L). The extracts were combined and concentrated under vacuum to obtain a residue (43 g). Analysis by high performance liquid chromatography showed that the n-hexane extract contained 21% of 7-hydroxytyrolactone.
Embodiment 3
[0209]Methanol extract of S. tomentosa (LI / DD-H / 054A / 03): Put S. tomentosa flower heads (1.0 kg) into an RB flask and extract with methanol (8 L) at 80°C for 2 After 1 hour, the extract was filtered and the extraction of the spent material was repeated twice with methanol (2x6L) under the same conditions. The combined extracts were fine filtered and concentrated in a rising film evaporator to obtain a residue (110 g). Analysis by high performance liquid chromatography showed that the methanolic extract contained 8.3% of 7-hydroxytyrolactone.
