A standardized protocol for genomic DNA isolation from Terminalia arjuna for genetic diversity analysis Electron. J. Biotechnol.
Sarwat,Maryam; Singh Negi,Madan; Lakshmikumaran,Malathi; Kumar Tyagi,Akhilesh; Das,Sandip; Shankar Srivastava,Prem.
For studying genetic diversity in natural populations of Terminalia, a medicinal plant, our attempts to isolate high quality DNA using several previously reported protocols and even modifications were unsuccessful. We therefore combined CTAB based isolation, and column based purification step, to isolate DNA from Terminalia arjuna. The DNA isolated using this standardized protocol was high in quality and suitable for restriction digestion and generation of random amplification of polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP).

Antidiarrheal effect of extract from the bark of Combretum leprosum in mice Anais da ABC (AABC)
CAVALCANTI,PAULO M.S.; MARTINS,MARIA DO CARMO C.; NUNES,PAULO H.M.; ALVES FILHO,FRANCISCO C.; SILVA,JANYERSON D.P.; CAVALCANTI,SUZANA M.G..
Abstract This study investigated the effects of the ethanolic extract from the bark of Combretum leprosum (ECL) on intestinal transit and castor-oil induced diarrhea in mice. The oral administration of ECL (750 and 1000 mg/kg) slowed intestinal transit (ID50 of 455 mg/kg). The ECL (250-1000 mg/kg) reduced castor-oil induced diarrhea, in a time- and dose-dependent manner (p < 0.05). To determine if antidiarrheal effect of ECL involves α2-adrenergic or opioid receptor activation, the mice were pretreated with antagonists of these receptors, yohimbine or naloxone respectively. None of these drugs inhibited the antidiarrheal effect of ECL. To test if antidiarrheal effect of ECL is due to an antisecretory action, we realized the enteropooling assay on rats....

Johann,Susana; Pizzolatti,Moacir G.; Donnici,Cláudio L.; Resende,Maria Aparecida de.
Antifungal properties of extracts from eight Brazilian plants traditionally used in popular Brazilian medicine were tested against five clinically relevant Candida species, Cryptococcus neoformans, and Sporothrix schenckii. Results demonstrate that almost all extracts exhibited antifungal activity, at least against one of the microorganisms tested. The ethanolic extract from the leaves of Schinus terebinthifolius exhibited potential antifungal activity against C. glabrata and S. schenckii. Preliminary phytochemical analysis of extract from S. terebinthifolius showed the presence of biologically active compounds, namely saponins, flavonoids, triterpenes, steroids and tannins.
