Constituents
– Aerial parts of P. auricularius yielded 4 cleistanthane type diterpenoids (C20), one of which is auricularic acid. Compounds shown to exhibit spasmolytic activity.
– Study yielded three novel diterpenoids from the whole plant of P. auricularis, namely: cleistanth-13,15-dien-18-oic acid and 7-hydroxy- and 7-acetoxycleistanth-13,15-dien-18-oic acids.
– Aerial parts yielded two diterpenes characterized as 7-(3-methylbutyroxy)cleistanth-13,15-dien-18-oic acid and 7-senecioxycleistanth-13,15-dien-18-oic acid.

Study Findings
• Diuretic Activity: In a screening of Indian plants for biologic activity, M auricularis showed diuretic activity.
• Spasmolytic Diterpenes: Two diterpenes, isolated from the aerial parts of Pogostemon auricularis, have been characterized as 7-(3-methylbutyroxy)cleistanth-13,15-dien-18-oic acid and 7-senecioxycleistanth-13,15-dien-18-oic acid.
• Cytotoxic / Thrombolytic / Leaves: Study evaluated a methanolic extract of leaves for cytotoxicy and thrombolytic activities. In Brine shrimp lethality assay, with vincristine as positive control, results showed a LC50 value of 10.51 µg/ml. Extract showed considerable thrombolytic activity exerting 42.1208% lysis of the blood clot.
