Delayed tendon healing is still found to be among the complications that occur most often after tendon repair. The role of local injection of Artemisia absinthium was evaluated in healing of experimental Achilles tendon injury in rabbits. In nine adult New Zealand rabbits a partial thickness tenotomy was created on both hindlimbs. A. absinthium extract and normal saline were respectively injected daily to treatment and control groups for three days. On the day 7 after injury, the tendon sections showed that healing rate in A. absinthium treated group was higher than that in control group. Furthermore, at days 14 and 28, comparison between A. absinthium treated group and control group demonstrated that A. absinthium increased the healing rate but with no significance. Results of this study have showed that application of A. absinthium extract can improve healing process of damaged Achilles tendon.
In preliminary experiments, we show that extracts from Artemisia absinthium, and Artemisia arborescens x absinthium “Powis Castle” have deterrent properties against neonate larvae of codling moth, Cydia pomonella. By partitioning crude extracts and comparative High Performance Thin Layer Chromatography we suggest candidate feeding deterrents for further analysis.
Aceria absinthii (Liro, 1943) and Paraphytoptus paradoxus Nalepa, 1896, are new species for the fauna of Serbia. The descriptions of both species are supplemented, with males described for the first time. A. absinthii causes galls on the lower surface of leaves, whereas P. paradoxus is vagrant on leaves of wormwood.
The aim of the study was to compare the content and composition of essential oil in wormwood herbs collected from eight natural sites in the Mrągowo administrative district. The raw material was harvested in the first ten days of August, separately from the plants being at vegetative and generative stage of development. The content of essential oil in the herb of flowering plants ranged from 0.90 to 1.45%, and in the herb of plants at the vegetative stage of development - from 0.60 to 0.94%. The main constituents of the essential oil were: sabinyl acetate (6 populations), sabinyl acetate and chrysanthenyl acetate (1 population), sabinyl acetate and β-thujone (1 population). In the essential oil of plants growing in Kol. Dluzec only some traces of β-thujone were found. All investigated essential oils were characterized by a relatively high content of cineol.
Plant derived extracts and phytochemicals have long been a subject of research in an effort to develop alternatives to conventional insecticides but with reduced health and environmental impact. In the present study, the aphid settling deterrent activity of extracts obtained from garlic (Allium sativum L.), wormwood (Artemisia absinthium L.) and tansy (Tanaceum vulgare L.) against peach potato aphid (Myzus persicae [Sulz.]) was investigated. The settling of M. persicae on host plant leaves was strongly deterred by soap 1%, soap 4%, Bioczos Forte 2% + soap 1%, Bioczos 1% + tansy extract 1%. Their effect was observed after 1 hour aphid had got access to the plants and it lasted until the end of the experiment, i.e. 24 hours after application. After 24 hours, aphid settling was deterred by the following combinations of extracts: Bioczos 2%, Bioczos 2% + soap 1%, Bioczos 5%, Bioczos 5% + soap 1%, Bioczos 1% + wormwood extract 1%, Bioczos 1% + wormwood extract 1% + soap, tansy extract 1% + wormwood extract 1% and tansy extract 1% + wormwood extract 1% + soap 1%.
