- Fresh leaves yield volatile oil, largely carvacrol.
- Phytochemical screening yielded carbohydrates, proteins, phenols, tannins, flavanoids, saponins, glycosides.
- Aerial parts yielded essential oil with 28 constituents, 16 of which were identified. Thymol (%) was the major compound, while 1-octen-3-ol, terpine-4-ol, eugenol, trans-caryophyllene, caryophyllene oxide and α-cadinol were present as minor constituents. ( 16 )
- Study of flowers and aerial parts for essential oils yielded four compounds from flowers oil and twelve from the aerial parts. The major constituent was carvacrol in flowers and aerial parts, % and % respectively. Other constituents were p-cymene, ß-caryophyllene, and trans-a-bergamotene. ( 17 )
- Aqueous leaf extracts yielded tannins, saponins, flavonoids, steroid glycosides, and polyuronides. GCMS yielded 11 chemical compounds (%), the principal constituents of which include linalool (%), nerol acetate (%), Germany acetate (%) and carvacrol (%). ( 34 )
- Essential oil yielded 26 compounds. Major compounds were carvacrol (%), thymol (%), α-humulene (%), undecanal (%), γ-terpinene (%), ρ-cymene (%), caryophyllene oxide (%), α-terpineol (%) and β-selinene (%). (see study below) ( 39 )
- Study survey shows the occurrence of 76 volatiles and 30 non-volatile compounds belonging to different classes of phytochemicals such as monoterpenoids, diterpenoids, triterpenoids, sesquiterpenoids, phenolics, flavonoids, esters, alcohols, and aldehydes. ( 42 )
- GC-MS study of leaf for volatile constituents yielded linalool (%) as major component, carvacrol (%), geranyl acetate (%), nerol acetate (%), y-terpinene (%), p-cymene (%), nerol (%), a-4-carene (%), caryophyllene (%), and ß-myrcene (%). ( 42 )
- Crude ethanolic extract of leaves yielded alkaloids, flavanoids, terpenoids, phenols,, saponins, carbohydrates, and protein. (see study below) ( 46 )
