Abstract

Phytochemicals are considered as one of the most important pharmaceutical compounds used in pharmacy at all, due to their high therapeutic efficacy and few side effects compared with chemically prepared drugs. On the other hand, the modern techniques of analysis such as GC-MS made it easier to know the chemicals that make up the materials to be studied. In our study, alcoholic extracts of (Punica granatum peel, Ziziphusspina-christi leaves, and Eucalyptus camaldulensis leaves) were prepared, in addition to prepare the mixtures of these extracts by mixing the equal proportions of two extracts only of three plant extracts each time. The result was 3 pure extracts and 3 mixture extracts. After that, these samples were analyzed with the GC-MS device, and the results of the analysis were compared with each other to find out the structural differences occurred after mixing. The results proved the presence of new chemical compounds in the mixture extracts completely different from the chemical compounds found in the pure compounds, whether in terms of chemical composition or biological activity.

Introduction

Pure compounds from natural sources or pure plant extracts can be considered as sources for newer drugs [1]. World Health Organization (WHO) considered that about 80% of humans rely on folk medicine for their primary healthcare care. The use of medicines from herbal sources in Asia gives a long history of contact between human and the environment. In traditional medicine, there are phytochemicals used to treat chronic diseases and infections [2]. Because of the side effects and bacterial resistance in synthesized drugs, human turned to use botany. There are thousands of chemical compounds from plants sources that are safe and effective alternatives with fewer side effects [3].

Punica granatum; a granular apple [4]. Pomegranate from the family punicaceae are fruits to the Mediterranean region. The edible part of the fruit contains many phytochemicalsas saccharides, polyphenol, and some minerals. The major class of pomegranate chemicals is the polyphenols such as phenolic rings with many hydroxyl groups. Pomegranate polyphenols comprise flavonoids such as flavanols, flavonols and anthocyanins, also condensed tannins and hydrolysable tannins [5].

Eucalyptus camaldulensis is an important plant belonging to the family, Myrtaceae, is used as a medicine for treatment of sore throat and some other bacterial infection of the respiratory and urinary tracts. The essential oils in the leaves are used as an expectorant to treat lung disease [6]. The alcoholic extract and the aqueous extract of Eucalyptus camaldulensis were found to be effective in inhibiting different types of Gram-positive and Gram-negative bacteria [7].

Ziziphusspina-christi has important fruits that usually eaten freshly. The fruits can be applied on wounds and ulcers [8, 9]. Pneumonia, dysentery, scorpion bites, cough, constipation, intestinal worms, and fever are some of the uses of this plant [9, 10]. It has shown that extracts of leaves of this plant has anti-microbial, anti-nociceptive, and anti-diabetic effects [11]. The extract of Ziziphusspina-christi also contains beutic acid and ceanothic acid, cyclopeptides also contain saponin glycosides, protein, free sugar and mucilage that have the anti-bacterial activity [8 10].

Gas chromatography-mass spectrometry (GC-MS) is considered as a method that performed coupling between the features of gas-chromatography and mass spectrometry to identify different compounds in the sample. GC can separate essential and semi-essential compounds with a great resolution, but it cannot diagnose them. MS can give the whole structural information about most chemicals that can be precisely identified, but it cannot readily isolate them [12].

The study aims to identify the chemical compounds resulting from mixing the following plant extracts (Punica granatum peels and Ziziphusspina-christi), (Punica granatum peels and Eucalyptus camaldulensis leaves) and (Ziziphusspina-christi and Eucalyptus camaldulensis leaves) and compare them with the chemical compounds of these extracts, while they are in their pure state, by using the GC-MS technique, and studying the biological activity of these compounds in theory, to make room for many other studies carried out by mixing plant extracts, identifying the resulting compounds, and studying the chemical reactions that occur as a result of the mixing process that led to the production of contrasting compounds, and also an applied study of the effectiveness of these compounds.

Materials and Methods

Collection of the plant material

Punica granatum peel, Ziziphusspina-christi, and Eucalyptus camaldulensis leaves were collected fresh and free from any abnormal condition or disease. They were collected from local farms in the Holy Karbala/Iraq. The raw materials were washed well with tap water, and then with distilled water more than once. After that, they were dried in the open air for a period ranging between 8-10 days. Next, it is ground by using an electric grinder for a period ranging from 4-6 minutes, and then it was stored in closed bottles until use.

Preparation of alcoholic extracts

Eucalyptus camaldolehsis leaves and Ziziphusspina-christi leaves.

20 g of the sample were weighted and put in the Soxhlet with 400 mL ethanol (70% for Eucalyptus and 95% for Ziziphusspina-christi concentration) for one day [13] (Table 1).

20 g of sample with 400 mL of ethanol (70%) was mixed by magnetic stirrer for 2 hours, and then the sample was steeped for one day, filtered, and centrifuged (3000 C/min for 10 minutes) [14].

Preparation of mixture extracts

3 mixture extracts were prepared by mixing 30 mL of each extract of the pure extracts and mixing it with 30 mL of the other extract by means of a magnetic stirrer for 3 minutes after which the resulting mixture extracts were stored in refrigeration until use.

Analysis by using GC-MS technology

30 mL of each sample of the extracts (pure and mixed) were taken and sent well cooled to the GC MS lab in the Department of Food Sciences at the College of Agriculture/University of Basra/Iraq (Table 2).

Conclusion

It can be mentioned that the preparation of three mixture extracts prepared by mixing (1:1) two of each of the pure extracts separately, demonstrated us new chemical compounds that differ from the chemical compounds appeared in the pure extracts, by conducting chemical analysis by using the GC-MS technique. These new chemical compounds were identified in each of the prepared extract blends and their benefits are theoretically studied.  It should be noted that this these compounds are naturally present in other sources or may be chemically prepared in the laboratory, but they are not presented in the original extracts from which they were prepared, and therefore it is a simple and new way to mix pure extracts and prepare new chemical compounds with different biological activity.
