A new dolabrane-type diterpene named tagalsin O 1, together with six known analogues 2-7, were isolated from the aerial part of the mangrove plant Ceriops tagal. The structures and relative configurations were elucidated on the basis of their spectroscopic data. Cytotoxicity of the isolated
Two new phenylpropanoids, tagalphenylpropanoidins A-B (1-2), together with a known analogue, 2,3,6-trimethoxy-5-(1-propenyl)phenol (3), were isolated from the ethanolic extract of the Chinese mangrove Ceriops tagal. The structures of these compounds were determined by extensive spectroscopic
Six new dolabranes, named tagalsins P-U (1-6), were isolated from stems and twigs of a Chinese mangrove, Ceriops tagal, along with seven known dolabranes, an abietane, and a pimarane. The structures of these compounds were established on the basis of spectroscopic data or comparison with data in the
Two new dolabrane diterpenes, tagalenes J and K (1 and 2), together with eleven known analogues (3 - 13), were isolated from the ethanolic extract of the Chinese mangrove Ceriops tagal. The structures of these compounds were determined by extensive spectroscopic analysis, including 1D-, 2D-NMR and
Four new diterpenes named tagalons A-D (1-4), comprising an isopimarane (1), two 16-nor-pimaranes (2-3), and a dolabrane (4), were isolated from the Chinese mangrove, Ceriops tagal, together with four known dolabranes containing a 4,18-epoxy group, viz. tagalene I (5), 4-epitagalene I (6), tagalsin
The objective of this study was to investigate the effects of mangrove tea on salivary bacterial flora in DMBA induced hamster buccal pouch carcinoma. Tea from mangrove plant Ceriops decandra was administered against DMBA induced buccal pouch carcinoma in hamster rats. The chemical constitutions and
The embryo of Ceriops tagal was extracted with 95% ethanol at room temperature, and four triterpenes (1-4) were separated from this extract. For the first time these triterpenes were the separated from this plant. Compounds (1-4) were tested in vitro for antitumor activity against three cell lines
Chemical examination of the barks of mangrove plant Ceriops tagal resulted in the isolation of six new dolabrane-type diterpenes with the trivial names of tagalenes A-F (1-6), together with 10 known analogues. The structures of new compounds were elucidated by extensive spectroscopic data analyses.
Gallic acid (PubChem CID: 370) and quercetin (PubChem CID: 5280343) are major phenolic compounds in many mangrove plants that have been related to health cure. In the present study, the active fractions namely gallic acid (1) and quercetin (2) were isolated from the methanolic extract
Ceriops decandra is a mangrove tree species, reputed for its folkloric uses in the treatment of gastrointestinal disorders, infection, snakebites, inflammation, and cancer. Different parts of the plant are rich with various phytoconstituents which include diterpenoids (ceriopsin A-G), triterpenoids
Two new cyclic depsipeptides, W493 C (1) and D (2), along with two known derivatives W493 A (3) and B (4) were obtained from the endophytic fungus Fusarium sp. isolated from the Mangrove plant Ceriops tagal. The structures of the new compounds were determined on the basis of one- and two dimensional
Two new polyketides, cytospyrone (1), cytospomarin (2), together with three known metabolites dimethoxyphtalide (3), integracin A (4) and integracin B (5), were isolated from the culture of Cytospora sp. from the Chinese mangrove Ceriops tagal. Their
