Structures of Six Coleons (Diterpenoids) from Solenostemon monostachys (P. B EAUV .) B RIQ . ( Labiatae ) The above mentioned African labiate has been investigated for its leaf‐gland pigments. Besides the already known coleons C ( 1 ) and H ( 2 ), 2 a ‐formoxy‐coleon C ( 3 ), 12β‐ O ‐acetyl‐coleon Z ( 7 ), 12β‐ O ‐acetyl‐7‐ O ‐formyl‐7‐ O ‐desacetyl‐coleon Z ( 8 ) and a not separated mixture of 17‐acetoxy‐12β‐ O ‐acetyl‐coleon Z ( 9a ) and 12β‐ O ‐acetyl‐17‐formoxy‐coleon Z ( 9b ) have been isolated.
