F. communis and D. viscosa are perennial Mediterranean weeds that have been used for different therapeutic purposes in traditional pharmacopeia. Plant extracts were obtained from air dried D. viscosa young shoots (DvA) and F. communis aerial part (FcA) and roots (FcR) with n-hexane. The chemical compositions of the extracts were analyzed by HPLC-DAD, LC-MS (ESI) and LC-Q-TOF techniques. Two sesquiterpene lactones (inuviscolide, tomentosin) and three sesquiterpene acids (costic acid, hydroxycostic acid, ilicic acid) were identified from the D. viscosa extract, while in F. communis extracts three daucane sesquiterpenes (acetoxyferutinin, oxojaeskeanadioyl anisate, fertidin) and one coumarin (ferulenol) derivates were found. Biological activities of plant extracts were studied in in vitro experiments on the colonies and conidia of Botryotinia fuckeliana, Penicillium digitatum, P. expansum, Monilinia laxa, M. fructigena and Aspergillus spp. Extracts showed varying degree of antifungal activities on colony growth and conidia germination. The extract from FcA showed the least effect, while DvA extract had the strongest fungitoxic effects. FcR extract presented a fungitoxic effect on the colony growth, but it was not able to inhibit the conidia germination. These distinctions can be attributed to the differences in chemical composition of plant extracts.
普通矢车菊和绒毛矢车菊是多年生地中海杂草,在传统药学中被用于不同的治疗目的。从空气干燥的绒毛矢车菊幼枝(DvA)和普通矢车菊地上部分(FcA)和根(FcR)中用正己烷提取植物提取物。采用 HPLC-DAD、LC-MS(ESI)和 LC-Q-TOF 技术分析提取物的化学成分。从 DvA 提取物中鉴定出两种倍半萜内酯(inuviscolide,tomentosin)和三种倍半萜酸(costic acid,hydroxycostic acid,ilicic acid),而在 FcA 提取物中发现了三种大根香叶烯倍半萜(acetoxyferutinin,oxojaeskeanadioyl anisate,fertidin)和一种香豆素(ferulenol)衍生物。在体外实验中研究了植物提取物对 Botryotinia fuckeliana、Penicillium digitatum、P. expansum、Monilinia laxa、M. fructigena 和 Aspergillus spp. 菌落和分生孢子的生物活性。提取物对菌落生长和分生孢子萌发表现出不同程度的抗真菌活性。FcA 提取物的影响最小,而 DvA 提取物具有最强的杀菌作用。FcR 提取物对菌落生长具有杀菌作用,但不能抑制分生孢子的萌发。这些差异可归因于植物提取物化学成分的差异。
