Fractionation of the chloroformic extracts from Teucrium ramosissimum leaves resulted in the isolation of three flavonoids: genkwanin (1), cirsimaritin (2) and 4',7-dimethoxy apigenin (4) and one sesquiterpene: β-eudesmol (3). The structures were determined using data obtained from (1)H and (13)C
Uncontrolled inflammation may produce massive inflammatory cytokines, in which interleukin 1β (IL-1β) plays a key role, resulting in tissue damage and serious disorders. The activation of NLRP3 inflammasome is one of the major mechanisms in maturation and release of IL-1β. Plectranthus
Centaurea bruguierana subsp. belangerana was extracted by 80% ethanol. The total extract was then partitioned into four fractions including chloroform, ethyl acetate and methanol. Cytotoxic effect of fractions was examined by MTT assay in K562 (chronic myelogenous leukemia), AGS (gastric
We investigated whether Cirsium maritimum Makino can inhibit immunoglobulin-E-mediated allergic response in rat basophilic leukemia (RBL-2H3) cells and passive cutaneous anaphylaxis (PCA) in BALB/c mice. In vitro, the ethyl acetate extract of C. maritimum Makino (ECMM) significantly inhibited
Dracocephalum kotschyi Boiss. has been used as part of an ethnobotanical remedy against many forms of human cancer in Iran. It has been demonstrated that a flavonoid named xanthomicrol from D. kotschyi contributes to its preferential antiproliferative activity against malignant cells. In the present
