Evaluation of phenolic content of common bean (Phaseolus vulgaris L.) in association to bean fly (Ophiomyia spp.) infestation
Common bean is the most important pulse crop in Kenya, though small scale farmers have limited access to pest resistant seeds. This has therefore made common bean yields remain below 1000kgha-1, while the potential is 2000kgha-1. However phenolics are secondary metabolites present in plants and this could be an attribute contributing to common beans resistance […]
Evaluation of potential cytotoxicity of the extracts from soft corals collected from the Philippine Sea of Mindanao: Sarcophyton glaucum, Lobophytum pauciflorum, Sinularia flexibilis and Lobophytum crassum
Soft corals have been shown to possess a rich variety of marine secondary metabolites and are considered an extremely diverse group of marine organisms. This study explored the potential cytotoxicity of soft corals collected from the Philippine Sea of Mindanao namely Sarcophyton glaucum (Sg), Lobophytum pauciflorum (Lp), Sinularia flexibilis (Sf) and Lobophytum crassum (Lc). Polar […]
Growth, phytochemical profile, and antioxidant activity of cultivated tabat barito (Ficus deltoidea Jack) under drought stress
Tabat barito (Ficus deltoidea Jack.) is one of the most important medicinal plants in Kalimantan. The growth, phytochemical profile, and antioxidant activity were assessed in Ficus deltoidea growing under four different water field capacity (FC) condition, namely: W1 (40% FC), W2 (60% FC), W3 (80% FC), and W4 (100% FC-control), and investigated for 9 months. […]
Yields, zoochemical profiles, and antioxidant activities of extracts from freshwater clam (Corbicula fluminea) using different solvents
Freshwater clam is among the many aquatic organisms that possessed many medical and biological effects. Several factors may affect the growth of phytoplankton, and so will likewise affect the secondary metabolites present. The study aimed to determine the crude extract yields, zoochemical profiles, and the antioxidant activities of the freshwater clam (Corbicula fluminea) using ethanol, […]
Households waste water effects on medicinal plant (Achillea santolina L.) and its soil characteristics
This investigation was done in botanical garden university of Balochistan Quetta, medicinal plants Achillea santolina L. were irrigated by four different types of water including municipal waste water, semi-treated wastewater, completely treated waste water and ground water (Tube well). Results of the study indicated that the continual usage of polluted water for irrigating purpose led […]
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 […]
Interactive effect of drought and sea water treatments on metabolic profile of two different Moringa species
Current study deals with the assessment of interactive effect of drought and sea water treatment on primary and secondary metabolic contents of Moringa peregrina and M. oleifera. Different intervals (2, 7 and 14days) of drought and alternating concentrations (0, 10, 25, 50, 75 and 100%) of sea water were interactively integrated with both species of […]
