The study was initiated to determine the anticancer activity of a novel compound isolated from the plant Mimosa pudica. The structure of the compound was identified as a derivative of myricetin having alkyl, hydroxy alkyl and methyl substitutions on the basis of spectral evidences (UV-vis, FT-IR, ...

Flaveria bidentis(L.) Kuntze is a serious invasive plant with allelopathic properties in Hebei, China. To obtain the herbicidal substance from the root extracts of F. bidentis effectively and rapidly, the isolation and purification method was optimized by using high-speed counter-current...

Mediterranean is exposed to intense impact of new lessepsian migrant species. The effects alien species are observed on native species, marine ecosystems and fisheries. However, the effects of pufferfish belongs family of Tetraodontidae is gaining more importance among allien species. Pufferfish...

A new flavonoside, namely cirsimarin B (1), along with two known compounds cirsimarin (2) and acteoside (3), were isolated from the aerial parts of the invasive plant Macfadyena unguis-cati. Their structures were elucidated by extensive spectroscopic analyses (IR, FT-ICR-MS, 1D and 2D NMR) and by...

Six polymethoxylated flavonoids were isolated from ethyl acetate fraction of ethanol extracts from Vitex rotundifolia Linn. f. fruit, and their structures were identified by NMR and MS methods, and cytotoxic activity of six compounds are analyzed by MTT method. The six compounds are oroxylin A (1), ...

Introduction - The freshwater aquatic plant Gymnocoronis spilanthoides (Senegal tea plant, jazmín del bañado, Falscher Wasserfreund) is an invasive plant in many countries. Behavioural observations of pyrrolizidine alkaloid-pharmacophagous butterflies suggested the presence of pyrrolizidine...

Eight new spiro- and furostanol glycosides that were tigogenin derivatives were isolated from pericarp of Yucca gloriosa fruit. The carbohydrate part of the furostanols contained 7-8 monosaccharides. The structures of the obtained compounds were elucidated using modern spectral methods.

Equisetum palustre L. is known for its toxicity for livestock. Several studies in the past addressed the isolation and identification of the responsible alkaloids. So far, palustrine (1) and N⁵-formylpalustrine (2) are known alkaloids of E. palustre. A HPLC-ESI-MS/MS method in combination with...

The use of algae as a foodstuff is rapidly expanding worldwide from the East Asian countries, where they are also used for medical care. Harmala alkaloids (HAlk) are a family of bioactive compounds found in the extracts of some plants, including wakame (Undaria pinnatifida), an edible marine...

Mimosa pudica Linn. (Family: Mimosaceae) is used as an ornamental plant due to its thigmonastic and nyctinastic movements. M. pudica is also used to avoid or cure several disorders like cancer, diabetes, hepatitis, obesity, and urinary infections. M. pudica is famous for its anticancer alkaloid,...
