A new γ-lactone named maroccanin (1) together with 5 known compounds : scopoletin (2); 8α-[2’hydroxymethyl-2’-butenoyloxy]-dehydromelitensin (3); 11,13-dehydromelitensin (4); 8α-[2’-hydroxymethyl-2’butenoyloxy]-sonchucarpolide (5) and 5Hα,6Hβ,7Hα,-15-hydroxy-8α-(1’,2’-dihydroxyethyl-acryloxy)-elema1(2),3(4),11(13)-trien-6,12-olide (6), were isolated from the chloroform soluble part of the aqueo...
We investigated the effect of FeSO4 on phagocytosis-associated, increased oxidative metabolism via the hexose monophosphate shunt, with special attention to its effect on H2O2 levels. The availability of glutathione peroxidase and glutathione reductase for H2O2 disposal and hexose monophosphate shunt stimulation also are evaluated. The results show an impairment of phagocytosis-associated hexos...
Different plant parts of Ligusticopsis wallichiana (family: Apiaceae) are widely used as traditional medicines. Although many volatile constituents are already identified from the leaves of L. wallichiana, there is no detailed report on the nonvolatile constituents. In the present study, we aimed to isolate and identify the major chemical constituents from the leaves. Bhutkesoside A (1), falcar...
The ethanolic extract from stems and leaves of Diospyros gracilipes Hiern showed moderate antimicrobial activity against Staphylococcus aureus (9 mm), Klebsiella pneumonia (7 mm) and Candida albicans (11 mm) using the disc diffusion assay. Fractionation of the extract led to the isolation of lupenone, ursolic acid, corosolic acid, a mixture of 3αand 3βtaraxerols, 3β-E-coumaroyltaraxerol, pinoce...
Sixteen compounds were extracted and purified from the leaves of Liriodendron tulipifera. These compounds include aporphines, oxoaporphine, coumarin, sesquiterpene lactone, benzenoids, cyclitol and steroids. (+)-Norstephalagine (2) (an aporphine) and scopoletin (8) (a coumarin) were isolated from Liriodendron tulipifera leaves from the first time. The identified compounds were screened for thei...
