The present study investigated the in vitro antiprotozoal activity of sixteen selected medicinal plants. Plant materials were extracted with methanol and screened in vitro against erythrocytic schizonts of Plasmodium falciparum, intracellular amastigotes of Leishmania infantum and Trypanosoma cruzi and free trypomastigotes of T. brucei. Cytotoxic activity was determined against MRC-5 cells to a...

Context. Many diseases are associated with oxidative stress caused by free radicals. Objective. The present study evaluated the in vitro antioxidant and antibacterial activities of various extracts of aerial parts of Periploca aphylla and Ricinus communis. Materials and Methods. In vitro antioxidant activities of the plant extract were determined by DPPH and NO scavenging method. Superoxide ani...

This present work reports an ecofriendly approach for the synthesis of gold nanoparticles (Au NPs) using aqueous stem extract of Periploca aphylla as a reducing and stabilizing agent, has been discussed. This approach is simple, cost-effective and stable for a long time, reproducible at room temperature and in an eco-friendly manner to obtain a self-assembly of Au NPs. Two parameters were optim...

Botanists and mycologists have long debated the potential for full myco-heterotrophy in the achlorophyllous Pyrola aphylla (Ericaceae). Here we address the ecophysiology of this putative myco-heterotroph and two other closely related green species in the tribe Pyroleae (Pyrola picta and Chimaphila umbellata). The stable isotopes of carbon and nitrogen (delta13C and delta15N) were analysed from ...

Liparis aphylla G.A.Romero & Garay was previously known only from two herbarium specimens collected in 1945 and 1977 in Ecuador and Colombia, respectively. This little-known species is hereby reported for the first time for Peru. An updated description, line illustration, color photographs and distribution map of Liparis aphylla, as well as an identification key to the Peruvian species of Lipar...

An ethnobotanical field study focusing on traditional wild food botanical taxa was carried out in Kaniguram, South Waziristan, Pakistan, among Ormur (or Burki or Baraki) peoples, which represent a diasporic minority group, as well the surrounding Pashtuns. Through sixty semi-structured interviews, fifty-two plants (taxa) were recorded, and they primarily used raw snacks cooked vegetables. Compa...
