Rosmarinic acid was present in all species of the subfamily Nepetoideae, but was absent from those in the subfamily Lamioideae. However, with the exception of 3 Lamioideae species, caffeic acid was found in measurable quantities in all taxa studied. The rosmarinic acid content ranged from 0.01 to 9.30 mg/g, while that of caffeic acid varied from 0 to 0.62 mg/g. (C) 1999 Elsevier Science Ltd. All rights reserved.

However, unlike the Lamioideae, all species of which had relatively high betaine levels, those members tested of the other major subfamily, the Nepetoideae, either gave low betaine yields or these compounds were not detected. The three species examined representing the Chloanthoideae contained compounds which reacted with Dragendorff's reagent, but their structures could not be determined because of the small quantities isolated.The betaines found in different species of the same genus were very similar, supporting the view that these compounds have taxonomic significance at the generic level.

Both triterpenoid acids were present in all of the investigated taxa, but the plants belonging in the subfamily Nepetoideae produced significantly higher amounts than those in the subfamily Lamioideae. The oleanolic acid content ranged from traces to 1.840% dry weight, and that of ursolic acid from traces to 4.019% dry weight. (c) 2006 Elsevier Ltd. All rights reserved.
