Two rarely phenolic acid-substituted alloses (1, 2) and one new glucoside (3), as well as nine known compounds (4-12) were isolated from rhizomes of Cibotium barometz (L.) J. Sm. Structures of 1-3 were established by extensively spectroscopic analyses (NMR, MS,
The pancreatic enzyme-II type collagenase digestion method was adopted for primary culture of osteoblasts, inoculation and passage. They were identified by alkaline phosphatase dye-liquor. N-butanol extract fractions from different processed products of Cibotium barometz were prepared. The above
OBJECTIVE
To study the chemical constituents from Cibotium batometz.
METHODS
Column chromatograph and HPLC were used to isolate and purify the compound, and the structure was elucidated on the basis of MS and NMR spectroscopic methods.
RESULTS
A new phenolic compound, 4-O-caffeoyl-D-glucopyranose,
Leaf extracts of five medicinal ferns, Acrostichum aureum L. (Pteridaceae), Asplenium nidus L. (Aspleniaceae), Blechnum orientale L. (Blechnaceae), Cibotium barometz (L.) J. Sm. (Cyatheaceae) and Dicranopteris linearis (Burm.) underwood var. linearis (Gleicheniaceae), were investigated for their
OBJECTIVE
This study was conducted to evaluate the antidermatophytic activity of 48 extracts obtained from medicinal plants (Cibotium barometz, Melastoma malabathricum, Meuhlenbeckia platyclada, Rhapis excelsa, Syzygium myrtifolium, Vernonia amygdalina) and marine algae (Caulerpa sertularioides,
