Chemical constituents and bioactivity of Formosan lauraceous plants

Abstract

Taiwan is rich in lauraceous plants. A review of 197 references based on the chemical analysis and bioactivity of indigenous lauraceous plants carried out by native scientists from 1963 to 2014 has been compiled. About 303 new compounds and thousands of known compounds comprising alkaloids and non-alkaloids with diverse structures have been isolated or identified from indigenous plants belonging to the 11 lauraceous genera. The volatile components, however, have been excluded from this review. This review provides an overview of the past efforts of Taiwan scientists working on secondary metabolites and their bioactivity in native lauraceous plants. The potential of lauraceous plants worthy of further study is also noted. The contents will be helpful for the chemotaxonomy of Lauraceae and be of value for the development of native Formosan lauraceous plants.

Phytochemical Investigation and Anti-Inflammatory Activity of the Leaves of Machilus japonica var. kusanoi

“…Compound 4 (1.0 mg, 3.5 µmol) and pyridine- d 5 (10.9 µL, 135.4 µmol) was transferred to a vial. The contents of the vial were dissolved in chloroform- d 1 (1090 µL, [ 4 ] = 3.5 mM). R -(−)-MPTA-Cl (10.9 µL, 58.3 µmol) was added to the vial, the vial was capped and the contents were stirred at room temperature (2–4 h).…”

“…They stand out, resulting in its economic benefits and diverse bioactivities. A previous investigation showed that some lauraceous plants exhibit bioactivities, such as cytotoxicity, anti-tuberculosis, anti-inflammatory, and antiplatelet activities [ 4 ]. Recently, we completed the anti-inflammatory screening of 174 methanolic extracts from 60 Taiwanese lauraceous plants.…”

“…The Machilus genus comprises about 100 species with accepted names, mainly distributed in East Asia [ 5 ]. Previous studies of Machilus species identified various classes of chemical constituents, such as lignans, flavonoids, and terpenoids [ 4 ]. M. japonica var.…”
