A preparation of Benja Amarit (BJA) has been effectively used in folk medicine to treat diseases related to the liver and colon and forms of cancer for hundreds of years in Thailand. However, there has not been any research on BJA with regard to its anticancer activity against human A bioassay-guided fractionation of the root extract of Angelica dahurica (Umbelliferae) led to the isolation of six furanocoumarins as active ingredients responsible for the antitumoral property. The hexane soluble part of the extract demonstrated a significant inhibition on the proliferation of
In the course of isolating agents preventing sepsis from the EtOAc extract of the roots of Angelica dahurica, four known furanocoumarins, isoimperatorin (1), oxypeucedanin (2), (+/-)-byakangelicin (3), and (+)-oxypeucedanin hydrate (4), were isolated as active compounds based on the in vivo assay
Phytochemical and pharmacological data on Ducrosia anethifolia (DC.) Boiss. (Apiaceae), an Iranian medicinal plant, are scarce; however, furocoumarins are characteristic compounds of D. anethifolia.Our experiments identify the secondary metabolites of D. We examined the effects of six furocoumarins with alkoxy groups at the C-5 or C-8 position isolated from Umbelliferae medicinal plants on cell proliferation, and their mechanisms of action against B16F10 melanoma cells or in melanin-possessing hairless mice implanted with B16F10 cells, under UVA
Ten coumarins were isolated from the root of Angelica dahurica by repeated silica gel column chromatography. Their chemical structures were elucidated on the basic of physicochemical and spectroscopic data. Among them, oxypeucedanin hydrate acetonide (7) was isolated for the first time from this
Phytochemical analysis of the dichloromethane:methanol (1:1) extract of root parts of Prangos pabularia led to the isolation of twelve cytotoxic constituents, viz., 6-hydroxycoumarin (1), 7-hydroxycoumarin (2), heraclenol-glycoside (3), xanthotoxol (4), heraclenol (5), oxypeucedanin hydrate (6),
Saposhnikovia divaricata (family Apiaceae) a traditional medicinal plant distributed in many provinces of China, is well known for the pharmaceutical value and has been used for rheumatic arthritis, and anxiety in children. Antiviral, antioxidant and antiproliferative activities were Allergic inflammation is induced by allergens and leads to various allergic diseases, including rhinitis, asthma and conjunctivitis. Histamine is important in the pathogenesis of an immunoglobulin E-dependent allergic reaction and results in the secretion of cytokines associated with inflammation.
