Impact of umbelliferone
(7hydroxycoumarin) on hepatic marker enzymes in streptozotocin diabetic rats.
Abstract: The chloroform fraction of Potentilla evestita led to the isolation of three compounds which were characterized as Acacetin 1, Chrysin 2 and Umbelliferone
(UMB) is a natural compound belonging to the coumarin family with antioxidant properties.
1%) were used for identification of single coumarin compounds in test samples: coumarin-3-carbosilic acid 99%, Aldrich; umbelliferone
99%, Aldrich; 3-hydrohycoumarin 97%, Aldrich; 7,8-dihydroxy-6-metoxy coumarin 98%, Aldrich; 6,7-dihydroxycoumarin 98%, Aldrich; dihydrocoumarin 99%; Aldrich.
Antihyperglycemic effect of umbelliferone
in streptozotocin-diabetic rats.
, a stress metabolite of (Chamomillarecutita L) .
2) The active ingredients of asafetida are the resin, endogenous gum, essential oil, propenyl-isobutylsulfide, umbelliferone
, and vanillin.
A especificidade do Tempo[R] EB para deteccao de enterobacterias pode ser entendida pela reacao que ocorre entre o micro-organismo e o meio de cultura presente nos frascos que contem uma molecula fluorescente, o 4-metil umbelliferone
(4MU), indicadora de pH (JOHNSON et al.
Kaempferol & Umbelliferone
were detected in refined sugars , tricin-T-glucosyl glucoside from mill syrup and several others have been identified by HPLC technique in sugar factory products (5,8).
Triorganotin(IV) derivatives of umbelliferone
(7-hydroxycoumarin) and their adducts with 1,10-phenanthroline:synthesis, structural and biological studies.
The herb contains flavonoids, carotenoids, hydroxycoumarins umbelliferone
and skimmine, also tannins, caffeic acid, fatty acids, lectins, etc (Antonyuk 2004, Chevallier 2000, PDR, 1998, Yakovlev and Blinova 1999).
On the basis of IR, NMR and mass spec data, this compound was shown to be umbelliferone
