Horminone, taxoquinone and other royleanones, obtained from two Abyssinian Plectranthus species ( Labiatae ). From the coloured glands on the leaves of two botanically unclassified Plectranthus sp. from Abyssinia, a series of royleanones has been isolated, namely royleanone ( 1 ) and 6,7‐dehydroroyleanone ( 2 ) from one species, and 6,7‐dehydroroyleanone, horminone ( 3 ), taxoquinone ( 4 ), 6β, 7α‐dihydroxyroyleanone ( 5 ), 7α‐acetoxy‐6β‐hydroxyroyleanone ( 6 ) and 7‐oxoroyleanone ( 7 ) respectively, from the other.
