Infestation and damage of black nightshade (Solanum nigrum) by black bean aphid (Aphis fabae) and red spider mite (Tetranychus evansi)

The black nightshade, Solanum nigrum Linn. (Solanaceae), is a widely distributed tropical plant used as a nutritive vegetable and herbal medicine in East Africa. This plant expresses high levels of secondary metabolites such as steroidal glycoalkaloids (SGA) and phytoalexins, which offer protection against pests and microbial pathogens. However, insect pests especially the black bean aphid […]

In vitro antifungal activity of Embelia schimperi (Vatke) and Conyza floribunda

The study aimed to investigate antifungal activity of 2 medicinal plants namely Embelia schimperi and Conyza floribunda used in Tanzania to treat infectious diseases. Micro-dilution method was used to evaluate antifungal activity of plant extracts against Cryptococcus neuformans and Candida albicans. The study revealed that tested extracts have different levels of antifungal activity with minimum […]

Construction of prokaryotic expression vector and expression of GbMYBFL protein

Flavonoids are one of the main secondary metabolites of Ginkgo biloba, and MYB is a transcription factor involved in regulation of flavonoid synthesis. In order to construct the prokaryotic expression vector of GbMYBFL from Ginkgo biloba and express the target protein, a pair of primers were designed with Bam H I and EcoR I restriction […]

Assessment of phytochemical constituents, antioxidant activity, cytotoxicity and antiproliferative activity of apricot

Medicinal herbs are having decisive role to improve the human health standard because of predominant bioactive constituents. Prunus armeniaca (Apricot) is a highly nutritious fruit with a rich composition of health promoting components with a unique taste. Apricot samples grown in Gilgit Baltistan were assessed for their biochemical attributes, FTIR interferogram profiling, Phytochemicals screening, antioxidant […]

Anti-proliferative activity of Thuja occidentalis seed extract through regulation of BAX and BCL-X gene exprssion

Cancer is one of the most devastating diseases which involve uncontrolled cell growth. The conventional treatments of cancer have strong side effects which leads scientists for seeking safer treatment option from nature. Various natural plants are well documented for having anti-proliferative activity with minimal side effects. Thuja occidentalis is one of the common medicinal plants […]

Comparison of in vitro antioxidant activity of Phellinus baumii and Trametes versicolor

The deleterious effects of oxidative stress caused by accumulation of free radicals in human body has gathered tremendous attention in the recent years. Wild medicinal mushrooms are rich in secondary metabolites that make them effective against a wide range of diseases. The present study was conducted to determine the antioxidant activity of two wild mushroom […]

Allelopathic effects of Palustriella falcata (Bryophyta) extracts on wild mustard plants

In order to protect themselves from various stress factors in certain habitats, bryophytes produce secondary metabolites such as phenolics. This study aimed to determine the effects of Palustriella falcata (Brid.) Hedenäs on growth parameters and levels of photosynthetic pigments, total protein, proline and total phenolics of Sinapis arvensis L. (wild mustard) to be used for […]
