Meliaceous limonoids: chemistry and biological activities.
This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about concrete mechanical properties such as E-modulus and compressive strength. Expand
Strynuxlines A and B, alkaloids with an unprecedented carbon skeleton from Strychnos nux-vomica.
The investigation of the seeds of Strychnos nux-vomica led to the isolation of two novel indole alkaloids, strynuxlines A (1) and B (2), with an unprecedented 6/5/9/6/7/6 hexacyclic ring system.Expand
Anthocyanin antioxidants from edible fruits
Abstract The edible fruits of 12 plants were extracted in methanol and subjected to solvent–solvent partitioning to yield three fractions, hexane, ethyl acetate, and aqueous. The semi-purifiedExpand
Cytotoxic Indole Alkaloids from Melodinus fusiformis and M. morsei
Abstract Aim To investigate antitumor indole alkaloids from the leaves and twigs of Melodinus fusiformis and M. morsei . Methods The indole alkaloids were isolated by column chromatography andExpand
Bioactive novel polyphenols from the fruit of Manilkara zapota (Sapodilla).
Activity-guided fractionation of a methanol extract from the fruit of Manilkara zapota cv. Tikal resulted in the isolation of two new antioxidants, methyl 4-O-galloylchlorogenate (1) andExpand
Pharmacological evaluation of Alstonia scholaris: anti-inflammatory and analgesic effects.
The alkaloid fraction of Alstonia scholaris leaf, three main alkaloids, picrinine, vallesamine and scholaricine, may produce the anti-inflammatory and analgesic effect peripherally based on several in vivo assays. Expand
Sterols and terpenoids from Melia azedarach.
Three new sterols including an unprecedented ring A-seco natural product (1) and five new terpenoids (4-8) were isolated from the bark of Melia azedarach, and the structure of 1 was confirmed by X-ray crystallography. Expand
Melodinines A-G, monoterpenoid indole alkaloids from Melodinus henryi.
Nineteen monoterpenoid indole alkaloids including seven new ones, melodinines A-G (1-7), were isolated from Melodinus henryi. The structures of the new compounds were elucidated using spectroscopicExpand
Cytotoxic indole alkaloids from Tabernaemontana divaricata.
Alkaloids 1 and 2 are the first vobasinyl-ibogan-type alkaloids possessing a six-membered ring via an ether linkage between C-17 and C-21, and show significant bioactivity against human cancer cell lines. Expand
Alkaloids from Melodinus yunnanensis.
Meloyine I showed weak cytotoxic activity against four human cancer cell lines: MCF-7 breast cancer, SMMC-7721 hepatocellular carcinoma, HL-60 myeloid leukemia, and A-549 lung cancer. Expand
