Two New Flavones from Inula grantioides
Inula grantioides (Boiss.) syn. /. cutchica Clarke is found in South West Pakistan, Karachi (Sindh), Kutch, Indus delta and Baluchistan. The plant is recommended for the treatment of asthma. This plant has not been subjected to chemical investiga tion so far. In the present paper we wish to report the isolation of two new flavones, grantionin 1 and grantioidinin 2 along with pluchidione 3, a k...
متن کاملSesquiterpene lactones from Inula montana L.
Aerial parts of Inula montana were investigated for its sesquiterpenoid composition. Five sesquiterpene lactones, isoinuviscolide, gaillardin, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15), 11(13)-dien-12-8beta-olide, pulchellin-C and pulchellin-E were identified for the first time in this plant. One of them, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15),11(13)-dien-1 2-8beta-olide, is a novel natural pr...
متن کاملAntitumour activities of sesquiterpene lactones from Inula helenium and Inula japonica.
Eight sesquiterpene lactones were isolated from the roots of Inula helenium and flowers of I. japonica. Among them, isoalantolactone (3) and santamarine (6) exhibited significant growth inhibitory activities against gynecologic cancer cell lines, while others weakly inhibited the growth of the cell lines (IC50 < or = 100 microM). In addition, 3 significantly inhibited the tumour growth of S180 ...
متن کاملFlavonoids from Halostachys caspica and their antimicrobial and antioxidant activities.
Seven flavonoids have been isolated from the aerial parts of Halostachys caspica C. A. Mey. (Chenopodiaceae) for the first time. By means of physicochemical and spectrometric analysis, they were identified as luteolin (1), chrysin (2), chrysin 7-O-β-D-glucopyranoside (3), quercetin (4), quercetin 3-O-β-D-glucopyranoside (5), isorhamentin-3-O-β-D-glucopyranoside (6), and isorhamentin-3-O-β-D-rut...
متن کاملAllelochemical, eudesmane-type sesquiterpenoids from Inula falconeri.
We have identified through bioassay guided isolation an allelochemical, eudesmane-type sesquiterpeniod, 3beta-caffeoxyl-beta1,8alpha-dihydroxyeudesm-4(15)-ene (1), from an endemic plant species growing in the Himalayas. In our search for the bioactive subfraction, the hexane one was highly significant, showing 100% inhibition of lettuce seed growth at 100 ppm while other subfractions (chlorofor...
