Chemical Analysis, Bacteriostatic and Fungistatic Properties of the Essential Oil of the Atoumau from Martinique (Alpinia speciosaK. Schum.)

Antimicrobial efficacy of extracts from Alpinia purpurata (Vieill.) K.Schum. against human pathogenic bacteria and fungi

“…To dertermine the potential medicinal use of plants it is important to screen them for activity against a wide range of pathogenic bacteria (Fazilatun et al, 2004). Although extensive research had been done with most Alpinia species including antimicrobial work (Pant,1999;Janssen and Scheffer 1985;Morita and Itokawa 1988;Haraguchi et al,1996;Miyazawa and Hashimoto 2002;Ray and Majumdar 1975;Ray and Majumdar 1976;Prudent et al,1993;Lima et al,1993;De pooter et al,1995) little or no work in terms of antimicrobial activities have been performed in A.purpurata. The objective of the present study is to assess the antimicrobial activities of extracts obtained from leaves, roots and rhizomes of A. purpurata using three different solvents ethanol, petroleum ether and chloroform.…”

Screening of various solvents and extracts of Achillea latiloba Ledeb. ex Nordm for antibacterial and antifungal activities

“…Neilreichii [22] have been reported. Moreover, the antibacterial properties of caryophyllene oxide have been revealed previously [23], while 1,8-cineole and camphor are also known to possess some antimicrobial activities [20,21]. Thus, the antibacterial properties of the essential oils A. taygetea and A. frasii are probably connected with their high content of 1,8-cineol and camphor.…”

“…The differences between the means in the same lines by the same letter are not statistically significant p>0.05 , *** = p<0.0016 mm: no inhibition, NT: not tested; But this species were not studied extensively [20,21]. However, the antimicrobial and histological data is sporadic and they are not comparable [20,21].…”

“…It should be pointed out that A. latiloba plant samples were more dissolved in The dimethyl sulfoxide (DMSO) and ethyl acetate A. latiloba plant samples were not fully soluble in methanol and ethanol. Currently, these genus were extensively studied [20][21][22]. Except from essential oils, the constituents of Achillea are mainly sesquiterpene lactones, flavonoids, and phenolic acids.…”

“…However, the antimicrobial and histological data is sporadic and they are not comparable [20,21]. The genus Achillea has been extensively studied in regard to its flavonoids [24].…”
