Bioassay-guided fractionation of extracts from Fructus Gardeniae led to analysis of its bioactive natural products. After infection by influenza virus strain A/FM/1/47-MA in vivo, antiviral activity of the extracts were investigated. The target fraction was orally administered to rats and blood was collected. High-performance liquid

HIV-1 activity was isolated from Black Clam crude extract by bioactivity-guided fractionation and was identified as Zinc diprolinate using NMR and Mass spectroscopic analysis. Zinc diprolinate was synthesized and antiviral screening assays indicated that it is a potent inhibitor of HIV-1 replication. 3.2 Materials and methods.
Bioassay guided fractionation was performed on the water extracts to isolate the active compounds. The actives were identified as trans-cinnamaldehyde and chavicol glucopyranoside with both compound showing potent anti-melanogenesis activity. At 4.9 µg/ml, both trans-cinnamaldehyde and chavicol glucopyranoside
bioactivity-guided fractionation (Pezzuto et al., 1997). In bioactivity-guided fractionation, the extract of an organism or a mixture of unknown molecules is fractionated and simultaneously biological activities of purified fractions are tested to determine the active fraction in each step of purification. In this process, extract.
4 Jul 2012 The success of modern methods in analytical chemistry sometimes obscures the problem that the ever increasing amount of analytical data does not necessarily give more insight of practical relevance. As alternative approaches, toxicity- and bioactivity-based assays can deliver valuable information about

A bioactivity-guided investigation of the ethanolic extract (70%) of the stem bark of Pterocarpus dalbergioides Roxb. ex DC revealed that the butanol fraction possessed potent antihyperglycemic and anti-inflammatory activities at a dose of 100 mg/kg b.wt. compared to metformin (150 mg/kg b.wt.) and indomethacin (20
The Indian Banyan is a large tree, bearing many aerial roots. An aqueous decoction of the fresh aerial roots of this tree has been used by traditional ayurvedic medical p..
4 Jul 2012 Frequently used terms are bioassay- or (bio)activity-guided fractionation, biochemical detection, and bioactivity screening. Most of them are mainly connected with drug discovery. Others, such as effect-directed analysis or bioresponse-linked instrumental analysis are more rooted in the environmental
