turpinia formosana/抗氧化剂

One new phenylpropanoid, turformosin A (1), and one new triterpene, turformosinic acid (2), together with 16 known compounds, were isolated from the stems of Turpinia formosana Nakai. All structures were elucidated on the basis of spectroscopic analysis, including 1D- and 2D-NMR techniques and MS

Bioassay-guided fractionation of the methanolic extract of Turpinia ternata stems, has led to the isolation of the new ellagic acid derivative 3,4'-di-O-methylellagic acid-4-O-alpha-L-arabinofuranoside (1), and the known compounds ellagic acid (2), 3-O-methyl ellagic acid (3), 3-O-methylellagic

Turpinia species have been used as local Chinese medicines. It has been widely concerned about their antibacterial and anti-inflammatory effects. Modern studies showed that the chemical constituents of Turpina species include flavonoids, triterpenoids, megastigans and phenoli acids. Its
