Structure elucidation of the new compounds was carried out using ID and 2D NMR spectroscopic data and single-crystal X-ray crystallography of compound 1. Compounds 1-4 exhibited selective antimycobacterial activity against Mycobacterium tuberculosis with IC50 values in the range 5.02-9.80 mu g/mL.</p>1 aKulkarni, Roshan, R.1 aShurpali, Ketaki1 aPuranik, Vedavati, G.1 aSarkar, Dhiman1 aJoshi, Swati, P.  uhttps://library.ncl.res.in/content/antimycobacterial-labdane-diterpenes-leucas-stelligera-0
