Myristica fragrans Houtt., the source of very important spice ‘nutmeg’ used world over is native to India, Indonesia, Sri Lanka, South Africa and Southeast Asia. Phytochemical investigation of M. fragrans stem bark led to the isolation of bis-aryl dimethyl tetrahydrofuran lignans, such as grandisin [(7S,8S,7′S,8′S)-3,3′,4,4′,5,5′-hexamethoxy-7,7′,8,8′-lignan] and (7S,8S,7′R,8′R)-3,3′,4,4′,5,5′-hexamethoxy-7,7′,8,8′-lignan along with important lignans and neolignans, licarinA, licarin B, odoratisol A, (2S, 3R)-7-methoxy-3-methyl-5-((E)-prop-1-enyl)-2-(5-methoxy,3,4-methylenedioxyphenyl)-2,3-dihydrobenzofuran, elemicin, fragransin B1, raphidecursinol B, erythro-(7S,8R)-Δ8′-4,7-dihydroxy-3,5,3′-trimethoxy-8-O-4′-neolignan, erythro-(7S,8R)-Δ8′-7-hydroxy-3,4,3′,5′-tetramethoxy-8-O-4′-neolignan, surinamensin.and β-sitosterol. Structures of the 12 compounds isolated...
