The capacity for nitrate reduction, as measured by nitrate reductase activity (NRA), was generally low for a range of plant communities in Australia (coastal heathland, rainforest, savanna woodland, monsoon forest, mangrove, open Eucalyptus forest, coral cay open forest) and only a loose relationship existed between NRA and leaf nitrogen concentration. This suggests that nitrate ions are not th...

This review article appraises the extraction methods, compositions, and bioactivities of the essential oils from the Citrus species (family: Rutaceae) endemic to Malaysia including C. aurantifolia, C. grandis, C. hystrix, and C. microcarpa. Generally, the fresh peels and leaves of the Citrus species were extracted using different methods such as steam and water distillation, Likens-Nikerson ext...

Ethnobotanical investigations on local oilseed species in Burkina Faso revealed that oils from tree oilseeds are frequently used for food, cosmetics and traditional medicine by local people. To test the bio-preservative capacity, the effect of the oilseed extracts on the stabilization of Shea butter was evaluated. Levels of bioactive phyto-components were evaluated through several methods. Some...

At Krymsk Experiment Breeding Station of VIR, as a result collecting, studying, and selective use myrobalan plum genetic diversity, the intraspecific taxonomy species Prunus cerasifera Ehrh. was clarified. Donors traits significant for breeding were identified and, with their use, adaptable cultivars plum, Russian clonal rootstocks stone fruit plants developed. Intraspecific classification P. i...

BACKGROUND Phaleria macrocarpa (Scheff.) Boerl (Thymelaceae) originates from Papua Island, Indonesia and grows in tropical areas. The different parts of the fruit of P. macrocarpa were evaluated for antioxidant, anti-inflammatory, and cytotoxic activities. METHODS Phaleria macrocarpa fruit were divided into pericarp, mesocarp and seed. All parts of the fruit were reflux extracted with methano...

Phaleria macrocarpa (Scheff.) Boerl (Thymelaceae) is commonly known as 'Crown of God', 'Mahkota Dewa', and 'Pau'. It originates from Papua Island, Indonesia and it grows in tropical areas. Empirically, it is potent in treating the hypertensive, diabetic, cancer and diuretic patients. It has a long history of ethnopharmacological usage, and the lack of information about its biological activities...

Leyland's cypress (xCupressocyparis leylandii) is a putative, spontaneous hybrid between Chamaecyparis nootkatensis and Cupressus macrocarpa. To investigate this putative origin, twenty five Leyland's cypresses were sampled, along with living, putative parents of Ch. nootkatensis and Cup. macrocarpa from gardens in the UK. The DNA was extracted and analyzed by DNA fingerprinting (RAPDs) and Int...

Two underutilized indigenous fruits of Borneo, Liposu (Baccaurea lanceolata) and Tampoi (Baccaurea macrocarpa) were investigated for their total phenolic (TPC), flavonoid (TFC), anthocyanin (TAC) and carotenoid (TCC) contents as well as antioxidant properties in vitro. The fruits were separated into three different parts (i.e., pericarp, flesh and seed) and extracted using 80% methanol. Antioxi...

The cochineal, Dactylopius opuntiae, has recently become the main pest that damages prickly cactus, Opuntia ficus-indica, plants in Morocco. control methods which pesticides are used and applied weekly, have generated phytotoxicity, poisoning high residuality fresh nopal, also prevents its commercialization international markets constant risk to human animal health. Therefore, use of less aggre...
