What is it about?
Leaves, pseudobulbs, or flowers of Prosthechea karwinskii are used to treat health problems, indicating that each part has different biocompounds with pharmacological activity. We characterize the biocompounds in extracts from each part of the plant.

Why is it important?
The compounds common to all three plant parts were quinic, malic, succinic, azelaic, and pinellic acids. Among the compounds identi!ed, two were exclusive to leaves, four to pseudobulbs, and ten to flowers. Some of the identified compounds have well-known antioxidant activity. The leaves had the highest content of total phenols and flavonoids, and the highest in vitro and ex vivo antioxidant capacity. A strong correlation was observed between phenol and flavonoid contents, and antioxidant capacity ex vivo and in vitro.
Perspectives
The bioactive compounds and antioxidant capacity of each part of the plant were associated with its traditional medicinal use. A pharmacological potential was also found in P. karwinskii for further biological studies because of the type of compounds it contained.
