The acaricidal (miticidal) activity of 90% ethanolic extracts of leaves and stem bark of Swietenia mahogani and Swietenia macrophylla were tested against Varroa destructor mite. Four concentrations were used over two different time intervals under laboratory and field conditions. In general, it was noticed that the acaricidal effect based on mortality and LC(50) of all tested extracts against t...
اثرات آنتیاکسیدانی فنل و فلاونوئید تام پوست درختان افرا (Acer velutinum) و توسکا (Alnus subcordata)
Background and Aim: Plants are a rich source of phenolic compounds as natural antioxidants are important. Antioxidant compounds that prevent the spread of diseases and the destruction of many of the foods they are extracted from the bark of Acer velutinum and Alnus subcordata trees. The purpose of this study the required the use of bark as the source of phenol is the pharmaceutical industry. Ma...
The anti-oxidative activities of sequentially extracted solvent fractions of different parts of P. biglobosa were evaluated in a series of in vitro assays. Our findings indicated that all extracts had electron donating and free radical scavenging activities. But the ethanol (EtOH) extracts from all the parts demonstrated more promising anti-oxidative effects in these experimental models. Apart ...
The extracts of the leaves and stem bark of anacardium occidentale were screened for phytochemically for the presence of secondary metabolites and for in vitro antibacterial activity. The phytochemical screening revealed the presence of alkaloids and tannins. The methanol and aqueous leaf extracts and the methanol extract of the stem bark were tested against Klebsiella pneumoniae, Staphylococcu...
Hot water extracts from eight medicinal plants representing five families, used for malaria treatment in Kenya were screened for their in vivo antimalarial activity in mice against a chloroquine (CQ) resistant Plasmodium berghei NK65, either alone or in combination with CQ. Extracts of three plants, Toddalia asiatica (root bark), Rhamnus prinoides (leaves and root bark) and Vernonia lasiopus (r...
it has been reported that several conifers possess cytotoxic activities on some human tumor cell lines. taxol as a natural cytotoxic compound has been extracted from this family. in a program to screen the cytotoxic effects of natural resources, male and female branchlets, fruit or bark of two different species of iranian conifers were collected, identified and the cytotoxic effects of their hy...
Microbial infections of various types of wounds are a challenge to the treatment of wounds and wound healing. The study was to investigate antimicrobial and antioxidant properties of methanol leaf and stem bark extracts of Kigelia africana and methanol leaf and root extracts of Strophanthus hispidus and also to determine wound healing properties of the extracts. The antimicrobial activities of ...
This study appraises the antioxidant and antimicrobial attributes of various solvent extracts (absolute methanol, aqueous methanol, absolute ethanol, aqueous ethanol, absolute acetone, aqueous acetone, and deionized water) from bark, leaves and seeds of Pongamia pinnata (L.) Pierre. Maximum extraction yield of antioxidant components from bark (16.31%), leaves (11.42%) and seeds (21.51%) of P. p...

Himatanthus articulatus (Vahl) Woodson is a tree found in the northern Amazon savannahs (common name: sucuba) that is used in local Amerindian medicine. Leaf, bark and branch wood methanol extracts, sequentially obtained hexane, ethyl acetate and methanol extracts and latex were evaluated for antifungal and antibacterial activities against American Type Culture Collection (ATCC) and local clini...
