Extracts from saffron, the dried stigmata from Crocus sativus L., are being used more and more in preclinical and clinical trials for the treatment of cancer and depression. Because of the known quality problems of saffron, HPLC methods on RP(18) 2.5 microm and monolithic RP(18) material have been developed and validated for quality control including the(More)
UNLABELLED ETNOPHARMACOLOGICAL RELEVANCE: The popularity of concentrated green tea extracts as dietary supplements for a wide range of applications is increasing due to their health-promoting effects attributed to the high amounts of catechins they contain. The most important of the green tea catechins is (-)-epigallocatechin-3-O-gallate (EGCG). While their(More)
Leaves from Phyllanthus muellerianus (Kuntze) Exell. are traditionally used for wound healing in Western Africa. Aqueous extracts of dried leaves recently have been shown to stimulate proliferation of human keratinocytes and dermal fibroblasts. Within bioassay-guided fractionation the ellagitannins geraniin (1), corilagin (2), furosin (3), the flavonoids(More)
Seven cyanopyridone derivatives and one corresponding seco compound have been isolated from a methanolic extract of the inflorescences and leaves of Acalypha indica L. (Euphorbiaceae). The absolute configuration of the main cyanogenic glucoside acalyphin, (-)-(5R,6S)-5-cyano-5-beta-d-glucopyranosyloxy-6-hydroxy-4-methoxy-1-methyl-2(5,6-dihydro)-pyridone,(More)
Ten compounds, harpagoside (1), 8- p-coumaroylharpagide (2), 8-feruloylharpagide (3), 8-cinnamoylmyoporoside (4), pagoside (5), acteoside (6), isoacteoside (7), 6'- O-acetylacteoside (8), cinnamic acid (9) and caffeic acid (10) were isolated from the storage roots of Harpagophytum procumbens, Pedaliaceae. Compounds 1, 2, 6, 7 and 9 are known for H.(More)

The majority of the people of Ghana and Africa still patronize traditional medicine for their health needs including various forms of wounds. The aim of this study is the identification of medicinal plants, type of wounds,(More)
ETHNOPHARMACOLOGICAL RELEVANCE Investigation of medicinal plant extracts traditionally used against uncomplicated urinary tract infections (UTI) and identification of antiadhesive effects under in vitro conditions against binding of uropathogenic Escherichia coli (UPEC) on bladder cell surface. MATERIALS AND METHODS Literature search on traditionally used(More)
The three major curcuminoids, curcumin, demethoxycurcumin and bis-demethoxycurcumin, from Curcuma domestica Val. (Curcuma longa L.) and Curcuma xanthorrhiza Roxb. (Zingiberaceae) were fully separated and quantified in less than 5 min using a capillary zone electrophoresis method with standard fused-silica capillaries and photodiode array detection. An(More)
Water-soluble high molecular weight compounds were isolated in yields of 21-22% from the oleogum of Boswellia serrata and B. carteri. Using anion exchange chromatography and gel permeation chromatography, different proteoglycans were purified and characterized, leading to four principally different groups: (i) Hyp-/Ser-rich extensins with O-glycosidic(More)
ETHNOPHARMACOLOGICAL RELEVANCE Eupatorium perfoliatum L. originates from North America, where it has been widely used since centuries by native Indians. Additionally extracts are used also in Europe as immunostimulating agent for treatment of fever and cold. The following review summarizes published data on phytochemistry, ethnopharmacological use, as well(More)
