Objective: Rosmarinus officinalis L. is an aromatic perennial herb with fragrant evergreen needle-like leaves, and it is member species of Lamiaceae family raised from Mediterranean region. The aims of the study were isolation, quantification, and identification of rosmarinic acid of R. officinalis leaves and essential oil analysis using various chromatographic and spectroscopic methods, and also cytotoxic and antibacterial investigation against different species of bacteria. Methods:It was isolated by preparative HPLC and preparative TLC, and then it was determined by HPTLC. The identification and the structural elucidation of isolated rosmarinic acid were performed by H-nuclear magnetic resonance, electrospray ionization mass spectrometry (MS), infrared, and ultraviolet. Essential oil was analyzed by Gas Chromatography/Mass. Results:Results highlighted that rosmarinic acid content was 0.9% and the oil content was 1.8%, and R. officinalis chemotypes of Iraqi rosemary oil were camphor 23.04%, 1, 8-cineole 14.01%, and terpinen-4-ol 13.8%. The rosemary chemotype characterized as a high concentration of terpinen-4-ol and good inhibition effect of rosemary methanolic extract against different species bacteria: Enterococcus faecalis, Staphylococcus saprophyticus, Acinetobacter baumannii, and Proteus mirabilis. Conclusions:The plant has a good content of rosemary phytochemicals and antibacterial effect, so the plantation of rosemary in Iraq has been successes. These isolated compounds are a suitable candidate for further clinical and pharmacological study.

Objective: The aim of our study was to investigate chemical constituents of leaves and seeds of Elaeagnus angustifolia since no phytochemical investigation had been done previously in Iraq.Methods: Phytochemical screening of the extracts obtained from the leaves of E. angustifolia indicated the presence of flavonoids (type of flavonols), saponins, alkaloids, steroids, and terpenoids. Thin-layer chromatography fingerprinting and the spraying reagent (concentrated H2SO4 and vanillin in ethanol) were used to identify the hexane extract containing phytosterols.Results: The different chromatographic and spectroscopic results revealed the presence of β‐sitosterol isolated from E. angustifolia. Conclusion: The isolation and purification afforded white crystalline powder which was subjected to chemical and spectral identification by infrared and 1H-nuclear magnetic resonance. The compound was identified as β‐sitosterol.

Plantago lanceoleta L. is one of medicinally important plant that officially registered in British pharmacopoeia. One of their well-known common name is ribwort, which is rich in many phytochemical compounds. The goal of this study is the qualitative evaluation of the Iraqi plant by identifying its chemical constituents. The plant was authenticated, collected, and immediately subjected to a stream of air under room temperature for rapid drying. Each part of the plant extracted separately with 50% ethanol and tested for presence of iridoid glycosides, tannins, flavonoids, terpenoids, alkaloids and saponins. While the other part of phytochemical screening of Iraqi P. lanceoleta L. in this work is the chromatographic fingerprint analysis of n-hexane extract of the plant leaves by gas chromatography-mass spectrometry (GC-MS). The result obtained show that Iraqi P. lanceoleta L. is rich in iridoid glycosides and tannins in each part of the plant, while the chromatogram of GC-MS show that the Iraqi plant contains high amount of hydrocarbons, fatty acids, steroids, terpenoids and other constituents.

Elaeagnus angustifolia, is from Elaeagnus genus and a member of the Elaeagnaceae family which is reported to have many species that are distributed throughout the world. The plant acquired a considerable importance because it is a rich source of vitamins such as   Tocopherol, carotene, vitamin C, thiamine B1 and minerals like calcium, magnesium, potassium, iron and manganese. from the phytochemical point of view, the plant was reported to contains: flavonoids, alkaloids, terpens, sterols and saponin. TLC fingerprinting was used to identify the ethyl acetate extract containing flavonoids. The isolation and purification afforded crystalline powder which were subjected to spectral identification by1H‐NMR and FT-IR. The compounds were identified as Isorhamnetin and Kaempferol.

Cressa cretica Fam: Convolvulaceae (morning glory). These plants are native to the tropical and subtropical areas of the world. Nutritional analysis provide it to be a potential source of minerals, energy, carbohydrate, alpha-tocopherol, edible oil. From phytochemical point of view, the plant was reported to contain: coumarins, sterols, alkaloids, tannins, glycosides, flavonoids, unidentified sugars and high salt content. Ethyl acetate layer and ethanolic layer were examined for cytotoxic activity.Kampferol-3-O-glucoside (Astragalin) was isolated as amorphous powder from the aerial parts of Cressa cretica. The flavonoid in the Iraqi plant was detected by TLC. Its presence was confirmed by HPLC.

Rosmarinus officinalis is one of the important bioactive medicinal plants belongs to labiatae family. The aim is to identifying the essential oil and rosmarinic acid extracted from rosemary leaves and to evaluate its anti bacterial activity. Gas Chromatography-Mass analysis was performed for essential oil of rosemary and HPTLC analysis was done for 90% methanolic extract of rosemary leaves. Rosmarinic acid was detected and The essential oil content was 1.5% and characterized with high amount of 1,8 cineol (53.63%) . The zone of inhibition of some bacteria was estimated. Our findings showed that rosemary leaves has Good percentage of rosemary phytochemicals (essential oil and rosmarinic acid) and has significant antibacterial activity against different species of bacteria.

Objective: Bauhinia variegata is evergreen small medicinal tree grows all over the world especially in the tropical regions. The aims of the study were detection, isolation quantification and identification of β-sitosterol and lupeol of Iraqi B. variegata stem using various chromatographic and spectroscopic methods, beside the cytotoxic investigation of hexane extract of different aerial parts. Methods: detection by GC mass spectroscopy, isolated by preparative TLC. The identification and the structural elucidation of isolated β-sitosterol and lupeol were performed by 1H nuclear magnetic resonance and FTIR. While the cytotoxic activity was performed against MCF-7 cells line. Results: Results highlighted that β-sitosterol and lupeol present in Iraqi B. variegata stem that confirmed by different chromatographic and spectroscopic analysis. Also the leaves extract has the superior action on MCF-7 cells followed by stem extract and end up by flower extract. Conclusions: The plant has a good content of both β-sitosterol and lupeol and the good cytotoxic action of aerial parts hexane extract confirm the successful plantation of B. variegata. These isolated compounds are a suitable candidate for further pharmacological study.
