Chemical investigation of the dichloromethane extracts of Andrographis paniculata(Burm.f.) Neesled to the isolation of squalene(1), polyprenol (2),lutein (3), chlorophyll a (4), and a mixture ofβ-sitosterol (5a) and stigmasterol (5b) in a 3:1 ratiofrom the stems; α-amyrin acetate (6), triacylglycerols (7), anda mixture of lupeol (8a), α-amyrin (8b), and β-amyrin (8c) in a 2:2:1 ratio from the leaves. The structures of 1-8c were identified by comparison of their NMR data with those reported in the literature.
