Abstract:
The first phytochemical investigation of the bark of Styrax suberifolius Hook. Et Arn. (Styracaceae) successfully isolated and identified seventeen phenylpropanoids, including ten benzofuran derivatives (1–10), two ditetrahydrofurans (11 and 12), two neolignans (13 and 14) and three phenyl alkanols (15–17). Compounds 2-(3-hydroxy-4-methoxyphenyl)-7-methoxy-5-benzofuranpropa- nol (5), (+)-cedrusin (6), (−)-(7R,8S)-dihydrodehydrodiconiferyl alcohol 4-O-β-d- glucopyranoside (8), (−)-(7S,8R)-dihydrodehydrodiconiferyl alcohol 4-O-β-d- glucopyranoside (9), (+)-(7S,8R)-dihydrodehydrodiconiferyl alcohol (10), (+)-(7S,8R) -erythro-4,7,9,9′-tetrahydroxy-3,3′-dimethoxy-8-O-4′-neolignan (13), (−)-symplocos- neolignan A (14), (−)-7-O-ethylguaiacylglycerol (15), 2-[4-(3-hydroxypropyl)-2- methoxyphenoxy]-1,3-propanediol (16) and dihydroconiferyl alcohol (17) have not been recorded in Styrax Linn. previously. The chemotaxonomic significance of isolated compounds is discussed.
