Saudi Journal of Biological Sciences, Journal Year: 2018, Volume and Issue: 26(7), P. 1695 - 1703

Published: Aug. 17, 2018

Propolis is a natural substance collected by honey bees from various plants such as, poplar, palm, pine, conifer secretions, gums, resins, mucilage and leaf buds. It brought very painstakingly to be used for sealing cracks crevices occurring in their hives. Originally, it as an antiseptic meant preventing bee-hive microbial infections along with decomposition of intruders. Additionally, propolis has been folk medicine centuries. The biological characteristics depend upon its chemical composition, plant sources, geographical zone seasons. More than 300 compounds have identified phenolic compounds, aromatic acids, essential oils, waxes amino acids. Many scientific articles are published every year different international journals, several groups researchers focused attention on the activity propolis.

Natural Compounds for Wood Protection against Fungi—A Review

Molecules, Journal Year: 2020, Volume and Issue: 25(15), P. 3538 - 3538

Published: Aug. 2, 2020

Wood is a renewable, versatile material with multiple applications and the largest terrestrial pool of sequestered carbon. However, it susceptible to degradation, mainly caused by wood-decaying fungi. Since several traditional wood preservatives have been banned owing their detrimental effects on humans environment, extending lifespan products using new generation natural an imperative from perspectives human health environmental protection. Several compounds plant animal origin tested for fungicidal properties, including essential oils, tannins, extractives, alkaloids, propolis or chitosan; enormous potential in protection has shown. Although they are not free limitations, methods overcome drawbacks enhance bioactivity already exist, such as co-impregnation different polymers, cross-linkers, metal chelators antioxidants. The presence discrepancies between laboratory tests field performance, well legislation-related problems resulting lack standards defining quality performance protective formulations, however, create urgent need further thorough research arrangements. collaboration other industries interested utilisation active will reduce associated costs, thus, facilitate successful implementation alternative antifungal agents.
