Received May 9, 2018; Revised July 1, 2018; Accepted July 10, 2018 Abstract Ammi visnaga (L.) Lam is a valuable herbal plant that is frequently collected for medicinal purposes. This study is conducted to evaluate the antimicrobial potential of the in-vitro grown microshoots and callus cultures of this plant against selected strains of bacteria and fungi. Shoot multiplication was obtained in MS medium containing 0.5 mg/L BA + 0.1 mg/L NAA, while callus multiplication was performed on MS medium containing 1.0 mg/L BA + 2.0 mg/L 2,4-D under light conditions. The aqueous and methanolic extracts were prepared from both culture types in addition to in-vivo grown plant material to experiment their antimicrobial activities. Generally, the in-vitro extracts of the microshoots and the callus cultures acted best against bacteria compared to the field plant extract. Moreover, the methanolic extracts were generally found to exhibit far better results and resistance against the tested microbes than the aqueous extracts. C. albicans was the most sensitive species to the microshoots extracts followed by gram-positive bacteria at MIC values of (3.125, 6.25) mg/mL. Meanwhile, E. coli bacteria were most sensitive to the microshoot extracts as they were completely inhibited at MIC value of (0.78 mg/mL). Moreover, the results of the callus extracts showed that C. albicans was the most sensitive at MIC values of (1.56 and 3.125) mg/mL, followed by gram-positive bacteria. On the other hand, gram-negative bacteria were the most resistant microbes to all experimented extract types in this study.

Introduction urbanization and uncontrolled collection caused overexploitation of wild plants particularly medicinal Ammi visnaga (L.) Lam is a herbaceous medicinal plant plants (Al-Quran, 2011). Moreover, about 90 % of the which belongs to the family Apiaceae. It is found mainly natural resources used by industries are collected from in the Mediterranean regions, and is also distributed wild plants. This is due to the difference in price between abundantly throughout the world as an introduced species. the wild and cultivated plants, which could explain the A. visnaga (L.) Lam is used frequently in many countries lack of favorable plant materials, or to the high demands as a herbal medicine for different purposes. Ancient for the wild materials, which resulted, in turn, in the records revealed various medicinal properties of this plant destruction of medicinal plants. Therefore, it has become as a popular source to cure a variety of different ailments an urgent matter to take legal measures and establish a (Hashim, et al., 2014). compact program for the sake of saving all medicinal Phytochemical studies on Ammi visnaga revealed the plants (Craker, 2007; Sharma et al., 2010; Tahtamouni, et diversity of its chemical constituents, as they comprise al., 2015). several groups each with several compounds. The most The recent development in biotechnology particularly important one includes Khellin (0.3-1.2 %) from the in the techniques of plant tissue culture have come as a furanochromones group (2-4 %) (Hammouda et al., 2005; boon to cope up with this alarming situation and to WHO, 2007; Sellami et al., 2013; Hashim et al., 2014; overcome these problems through the rapid Talaat, et al., 2014). It is worth mentioning that, micropropagation method in order to save the natural furanochromones particularly visnagin, khellin, and herbal wealth (Sridhar and Aswath, 2014). khellol-glucoside are exclusively extracted from two Initially, plant tissue culture was exploited as a research species only, which are A. visnaga (L.)

The best multiplication rate for the In addition to its traditional importance in preventing or microshoots was obtained in MS medium (Murashige and decreasing kidney stone formation in human patients, and Skoog, 1962) containing 0.5 mg/L BA in combination with its recent scientific importance against bronchial asthma 0.1 mg/L NAA, while the callus multiplication was best in and coronary diseases which are attributed to its essential MS medium containing 1.0 mg/L BA in combination with oils (Rose and Hulburd, 1992; Satrani et. al., 2004), Ammi 2.0 mg/L 2,4-D under light condition. To obtain the visnaga can be used as antitumoral (Beltagy and Beltagy, recommended mother stock for the present experiment, the 2015) and is considered as a good antifungal and microshoots (microshoot about 2.0 cm long and each flask antimicrobial agent against both gram-positive and gram- contained four microshoots) and callus clumps (clump negative bacteria (Rasooli et al., 2007; Dababneh, 2008; weight=0.5 g, with four clumps in each Petri dish) Ghareeb, et al., 2011; Khalfallah et al., 2011; Mahmood, underwent five subculturing intervals (four 2014; Sabry et al., 2014; Jaradat et al., 2015). weeks/interval).
