Pharmaceutical interest: The pharmacological potential of Pericampylus glaucus (Lamk.) Merr. remains unexplored. This plant is known to produce some alkaloids and triterpenes such as epifriedelinol and daucos-terol (Liang P et al., 1998; Tomita M et al., 1967). The anti-hair loss, anti-inflammatory and antipyretic properties of this plant are most probably due to isoquinoline alkaloids. Note that norreticuline and reticuline, benzyltetrahy-droisoquinoline alkaloids common in the Ranunculales, stimulate the proliferation of cultured cells from the murine hair apparatus and stimulate mouse hair regrowth (Nakaoji K et al., 1997). What is the mechanism involved here? a-receptors?
