“…An important active ingredient reported for sweetflag is -asarone, which has also been reported to act as potent nematicide in banana plantation in India [21]. Clove and the sweetflag extracts have been reported to contain 88% eugenol [33] and 45.5% -asarone [34], respectively. Therefore, the LC 50s of clove and sweetflag extracts would be equivalent to 3.4 and 5.2 mg eugenol and -asarone ml -1 solvent, respectively.…”

Nematicidal activity of extracts from plants was assayed against Meloidogyne incognita. In laboratory assays extracts from tobacco (Nicotiana tabacum L), clove (Syzygium aromaticum L), betelvine (Piper betle L), and sweet flag (Acorus calamus L) were most effective in killing the nematode, with an EC 50 that was 5-10 times lower than the EC 50 of the synthetic pesticides chlorpyrifos, carbosulfan and deltamethrin. The shapes of the dead nematodes differed in a characteristic way, and groups of pesticides and plant extracts could clearly be distinguished based on this phenomenon, which may be an indicator for the modes of action of the tested pesticides. In a greenhouse bioassay clove bud and betelvine were tested as mulch. Experiments revealed that the total number of live nematodes on roots of pepper plants treated with mulch of the clove bud was 7% of that of the controls and did not differ significantly from that of plants treated with the recommended synthetic pesticide carbofuran. The application of clove buds as a botanical pesticide for future use against nematodes is highly promising since clove is the 6 th major plant grown on Bangka Island, and the market value of clove has decreased sharply over the last years.

“…However, studies have reported wide differences in the components of A. calamus according to the growing habitat (Fujita et al, 1971;Raina et al, 2003). These variations of -asarone content are mainly due to their chromosomal ploidy differences and partially due to regional soil and climate influences (Venskutonis & Dagilyte, 2003). Table 2 presents the antimicrobial activities of the essential oil, hexane extract and the main constituents of A. calamus.…”

The constituents and antimicrobial activity of the essential oil from Acorus calamus were analysed. Methyl isoeugenol and cyclohexanone were identified as the major constituents of the essential oil. The essential oil was tested for antimicrobial activity against bacteria and yeast, and has shown strong antibiotic activities against most of the tested microbes, except Escherichia coli. The hexane extract has shown a similar pattern of antimicrobial activity as the essential oil. Methyl isoeugenol, the most abundant constituent in the essential oil, has also shown similar antimicrobial activity, except against Bacillus subtilis. The essential oil as well as the hexane extract and methyl isoeugenol have shown antimicrobial activity against Propionibacterium acne, which is known to be involved in acne vulgaris.

“…Ao analisar a variação do rendimento do óleo essencial ocorrida neste trabalho com outros relacionados ao tema, observa-se que realmente existe variação muito grande no rendimento de óleo essencial conforme a espécie, o método e o tempo de extração (Charles & Simon, 1990;Venskutonis, 2003;Jantan et al, 2003). Silva et al (2005) Prins et al (2006), constataram que no tempo de 90 minutos é possível conseguir uma maximização do rendimento de óleo essencial desta espécie.…”

(90, 120, 150, 180, 210 e 240 minutos) e 4 repetições. A extração do óleo essencial foi realizada por hidrodestilação e a análise química em CG-EM. O tempo de 180 minutos proporcionou maior rendimento do óleo essencial (0,42%), enquanto a composição química não foi influenciada pelos diferentes tempos de destilação. As principais substâncias identificadas foram: D-germacreno (65,5%), alfa-selineno (9,7%), trans-cariofileno (7,5%), e espatulenol (6,58%). Conclui-se que o tempo de extração afeta diretamente o rendimento e a proporção das substâncias químicas, recomendando-se a extração em até 180 minutos. The adopted experimental design was completely randomized, with six times of extraction (90, 120, 150, 180, 210, and 240 minutes) and 4 repetitions. The extraction of the essential oil was accomplished by hydrodistillation, and the chemical analysis was performed in GC-MS. The time of extraction of 180 minutes provided greater yield of the essential oil (0.42%), and its chemical composition was not influenced by the different times of hydrodistillation. The main substances showed are D-germacrene (65.5%), alpha-selinene (9.7%), trans-caryophyllene (7.5%) and spathulenol (6.58%). The results of this work showed that the time of extraction affects the yield and the proportion of the chemical substances and it is recommended the extraction in up to 180 minutes. Palavras
