Abstract
A phytochemical investigation on the whole plants of Aerides multiflora revealed the presence of three new biphenanthrene derivatives named aerimultins A–C (13) and a new natural phenylpropanoid ester dihydrosinapyl dihydroferulate (4), together with six known compounds ( [...] Read more.
A phytochemical investigation on the whole plants of Aerides multiflora revealed the presence of three new biphenanthrene derivatives named aerimultins A–C (13) and a new natural phenylpropanoid ester dihydrosinapyl dihydroferulate (4), together with six known compounds (510). The structures of the new compounds were elucidated by analysis of their spectroscopic data. All of the isolates were evaluated for their α-glucosidase inhibitory activity. Aerimultin C (3) showed the most potent activity. The other compounds, except for compound 4, also exhibited stronger activity than the positive control acarbose. Compound 3 showed non-competitive inhibition of the enzyme as determined from a Lineweaver–Burk plot. This study is the first phytochemical and biological investigation of A. multiflora. Full article

Abstract
We report the first phytochemical study of the neotropical orchid Cyrtopodium paniculatum. Eight new compounds, including one phenanthrene 1, one 9,10-dihydro-phenanthrene 2, one hydroxybenzylphenanthrene 3, two biphenanthrenes 45, and three 9,10 dihydrophenanthrofurans 68, [...] Read more.

The structures of the new compounds were established on the basis of extensive spectroscopic methods. Full article

Abstract
Five new biphenanthrenes, cremaphenanthrenes A–E (15), along with six known ones, were isolated from the ethanolic extract of the tubers of Cremastra appendiculata (D. Don) Makino (Orchidaceae). Their structures were elucidated on the basis of extensive spectroscopic analyses. All [...] Read more.
Five new biphenanthrenes, cremaphenanthrenes A–E (15), along with six known ones, were isolated from the ethanolic extract of the tubers of Cremastra appendiculata (D. Don) Makino (Orchidaceae). Their structures were elucidated on the basis of extensive spectroscopic analyses. All the compounds obtained were tested in vitro for cytotoxic activities against colon (HCT-116), cervix (Hela), and breast (MDA-MB-231) cancer cell lines. They all showed moderate or weak cytotoxicities to the above cancer cell lines. Full article
