Abstract

The bark of Litsea costalis affords two new compounds named 4,4'-diallyl-5,5'-dimethoxy-[1,1'-biphennyl]-2,2'-diol, biseugenol A (1) and 2,2'-oxybis (4-allyl-1-methoxybenzene), biseugenol B (2) along with two known compounds (3-4), namely 5-methoxy-2-Hydroxy Benzaldehyde (3), and (E)-4-styrylphenol (4). The structures of 1 and 2 were determined using 1D and 2D NMR data. Also, the IR and NMR data were combined with quantum chemical calculations in the DFT approach using the hybrid B3LYP exchange-correlation function to confirm the structures of the compounds. Compounds showed fairly potent anticancer activity against cell lines and antioxidant (DPPH).

Keywords: Cytotoxicity; DFT calculations; Extraction; Litsea costalis; NMR.
