„An infusion or decoction of the aerial parts of Fabiana imbricata (Solanaceae) is used in traditional medicine in Chile and Argentina as a digestive and diuretic agent. The main sesquiterpene of the plant was identified as 11-hydroxy-4-amorphen-15-oic acid. At doses of 25, 50 and 100 mg/kg, the compound showed a dose-dependent gastroprotective effect in HCl/EtOH-induced gastric lesions in mice reducing the lesions by 68% at 100 mg/kg.“

„“Pichi” or “pichi romero” (Fabiana imbricata R. et. P., Solanaceae) is a Chilean plant used as a tea in the Andean regions of Chile and Argentina. A very simple and direct method was developed for the qualitative analysis of polyphenols in the tea by high-performance liquid chromatography (HPLC) with diode array detection and electrospray ionization tandem mass spectrometry. The phenolic constituents identified in the teas were chlorogenic acid (3-O-caffeoylquinic acid), p-hydroxyacetophenone, scopoletin and quercetin derivatives. The glycosides were mainly glucosides from p-hydroxyacetophenone and scopoletin while di- and tri-glycosides from quercetin were the main flavonoids. The content of the main phenolic compounds in the teas (g/100 g lyophilized infusion) was 0.8–1.9 % for scopoletin, 0.4–6.2 % for p-hydroxyacetophenone and 2.1–4.3 % for rutin, respectively. The health-promoting properties reported for this herbal tea can be associated with the presence of several phenolics with known antioxidant, diuretic and antiinflammatory activity.“
