Chromosome Numbers and Evolution in Anoda and Periptera (Malvaceae)
Relationships within and between the principally North American, malvaceous genera A noda and Periptera are assessed through analysis of chromosomal and hybridization data. Chromosome numbers are reported for ten species of Anoda and one of Periptera, and observations on meiosis in hybrid and non hybrid plants are presented . The results indicate: I) that Anoda and Periptera are closely related...
متن کاملAnti‐asthmatic and anxiolytic effects of Herissantia tiubae, a Brazilian medicinal plant
Herissantia tiubae (HtE) is a Brazilian plant used in folk medicine to treat inflammatory diseases. Our aim was to determine whether the HtE has anti-inflammatory and anxiolytic effects in a murine model of asthma. Ovalbumin (OVA)-sensitized BALB/c mice were treated with HtE (50, 100, or 200 mg/kg) or dexamethasone before each OVA challenge. After the last challenge, animals were subjected to a...
متن کاملPollen, tapetum and orbicule development in Modiolastrum malvifolium (Malvaceae).
BACKGROUND AND AIMS Although orbicular functions are still a matter of debate, they are considered by most authors to be exclusively formed by a secretory tapetum. However, the presence of orbicules on a peritapetal membrane associated with a plasmodial tapetum has been described for Abutilon pictum (Malvaceae) in a previous study. Thus, studies on other species of Malvaceae are necessary to co...
متن کاملA new combination and taxonomic notes in Pseudobombax Dugand (Malvaceae)
Taxonomic notes in the Neotropical genus Pseudobombax (Malvaceae) are presented. One new combination and two new heterotypic synonyms for taxa originally described from Brazil and Ecuador are proposed based on both morphological and previously published molecular evidence. The taxonomic changes will be adopted in a treatment of Pseudobombax for the upcoming Brazilian Flora 2020 and in a forthco...
متن کاملNew Sulphated Flavonoids from Wissadula periplocifolia (L.) C. Presl (Malvaceae).
Wissadula periplocifolia (L.) C. Presl (Malvaceae) is commonly used in Brazil to treat bee stings and as an antiseptic. The antioxidant properties of its extracts have been previously demonstrated, thus justifying a phytochemical investigation for its bioactive phenolic constituents. This has yielded five new sulphated flavonoids: 8-O-sulphate isoscutellarein (yannin) (1a); 4'-O-methyl-7-O-sulp...
