The aim of this study was to carry out phytochemical analysis and antifungal evaluation of F. sycomorus L. stem and leaf Methanol extract on some dermatophytic fungi. The stem and leaf crude extracts were obtained after drying using maceration and percolation with methanol as the solvent. The extract was subjected to qualitative phytochemical screening as well as GC-MS analysis for the presence of bioactive constituents. The antifungal inhibitory effect of the crude stem and leaf extracts was assessed by agar well diffusion methods. The phytochemical screening revealed that the leaves and stem-bark contained secondary metabolites such as tannins, flavonoids, alkaloids, saponins, reducing sugar and steroid. The GC-MS assay showed that the most prevailing compound in the methanolic stem-bark extract was 2, 9, Diazabicyclo (4, 4, 0) decane-3,10 dione, while in the methanolic leaves extract was acetic acid. The anti-dermatophytic assay of the extracts against Microsporum canis and Tricophyton tonsurans showed that the extracts inhibited the fungi with zones of inhibitions ranging from 6.33±0.47 to 24.33±0.47mm with the leaf extract exhibiting higher inhibition zones than the stem extract (p˂0.01). The study shows that both the stem and leaf methanol extract of Ficus sycomorus L possesses antifungal activity and should be considered as a potential antifungal agent in search of newer agents to address dermatophytic fungal infections Key words: Ficus sycomorus L, Phytochemical/GC-MS Analysis, Antifungal activity

Previously tested n-hexane extracts of the Scorzonera latifolia showed promising bioactivity in vivo. Because triterpenes could account for this activity, n-hexane extracts were analyzed by HPLC to identify and quantify the triterpenes as the most abundant constituents. Other Scorzonera and Podospermum species, potentially containing triterpenic aglycones, were included in the study. An HPLC method for simultaneous determination of triterpene aglycones was therefore developed for analysis of Podospermum and Scorzonera species. n-Hexane extracts of root and aerial parts of S. latifolia, ten other Scorzonera species and two Podospermum species were studied to compare the content of triterpenes. HPLC was used for the qualitative and quantitative analysis of α-amyrin, lupeol, lupeol acetate, taraxasteryl acetate, 3-β-hydroxy-fern-7-en-6-one acetate, urs-12-en-11-one-3-acetyl, 3-β-hydroxy-fern-8-en-7-one acetate, and olean-12-en-11-one-3-acetyl. Limits of detection and quantification were determined for each compound. HPLC fingerprinting of n-hexane extracts of Podospermum and Scorzonera species revealed relatively large amounts of triterpenes in a majority of investigated taxa. Lupeol, lupeol acetate, and taraxasteryl acetate were found in a majority of the species, except S. acuminata. The presence of α-amyrin, 3β-hydroxy-fern-7-en-6-one-acetate, urs-12-en-11-one-3-acetyl, 3β-hydroxy-fern-8-en-7-one-acetate, and olean-12-en-11-one-3-acetyl was detected in varying amounts. The triterpene content could correlate with the analgesic and anti-inflammatory activity of Scorzonera, which was previously observed and Scorzonera species that have been determined to contain triterpenes in large amounts and have not yet been tested for their analgesic activity should be tested for their potential analgesic and anti-inflammatory potential. The presented HPLC method can be used for analysis of triterpene aglycones, for example dedicated to chemosystematic studies of the Scorzonerinae.

Aim: To compare the main and additive components of heroin trafficked in the Stateof Kuwait during 2012 with those components of heroin traded recently in the country during 2016 and 2017, and to provide a satisfactory explanation for the increase in deaths among heroin addicts during the period2011 -2018. Study Design: Selected samples of non-pure powder heroin seized in Kuwait during 2016 and 2017, with pure heroin and a set of10 pure different heroin component standards, all have been quantitatively analyzed in the Forensic Laboratories. Place and Duration of Study: All qualitative and quantitative analyses for 2016 and 2017 samples were conducted in the Forensic Laboratories of the General Department of Criminal Evidences – Ministry of Interior – State of Kuwait. Methodology: By using Gas Chromatography/Mass Spectrometry (GC/MS) to qualitative and quantitative analysis have been made on a total of hundred samples of non-pure powder heroin seized in Kuwait during the years 2016 and 2017, in addition to ten pure standards. Results: The concentration of the diacetylmorphine (active substance of heroin) in Kuwait during the year 2017 are much higher than the concentration during the year 2016. The additive substances (adulterants) for the years 2016 and 2017, are shared with the year 2012 by the component's paracetamol, caffeine and diazepam with different concentrations. But new adulterants in recent years are recorded in samples 2016 and 2017, including methamphetamine, dextromethorphan, and methylphenidate which is absent in 2016 samples. Conclusion: The concentration % of illicit heroin traded in Kuwait as diacetylmorphine has increase from 10% to 50% for year 2016, and further from 30% - 70% for year 2017, which marks identified a substantial rising in the purity of heroin. In addition, additive substances in the two years include paracetamol (acetaminophen), caffeine and diazepam, previously recorded in 2012. However, totally different new adulterates are recorded in 2016 and 2017 samples, including methamphetamine, dextromethorphan, and methylphenidate. All new three adulterates are detected in quite a few numbers of samples with methylphenidate recorded in a very low concentration of 0. 01 mg. Both new adulterates and higher purity of heroin constitute the main reasons for rising the rate of deaths between heroin addicts in recent years. Also, recent UN reports (12,18) provide evidence that the GC countries Afghanistan, Iran and Pakistan are still manufacturing and trading the above mentioned new adulterates.
