Tóm tắt
Stingless bees, which lack a functional sting, are distributed throughout most of the tropical and subtropical regions of the world, such as South America, Africa, Australia and Southeast Asia. Tetragonula laeviceps (Smith, 1857) is a species of stingless bee found in Southeast Asian countries. The extracts of T. laeviceps propolis showed many biological effects, but the chemical study of T. laeviceps propolis has been very limited. Chemical investigation of T. laeviceps propolis collected in Hoa Binh province (Viet Nam) led to the isolation of nine known compounds, including emodin (1), 3-geranyloxy emodin (2), 1,3,7-trihydroxy-2,4-bis(3- methylbut-2-enyl)xanthone (3), cudratricusxanthone F (4), 9-hydroxycalabaxanthone (5), α- mangostin (6), γ-mangostin (7), 1,3,5-trihydroxy-4-geranylxanthone (8) and pruniflorone I (9). Their structures were elucidated by MS and NMR spectral analysis and compared with those reported in the literature. This is the first investigation of T. laeviceps propolis in Viet Nam. Compounds 1–4, 8 and 9 were found in stingless bee propolis for the first time.
