Abstract
Peptic ulcer disease is one of the most serious gastrointestinal disorders that affect large number of people worldwide and it considered one of the major causes of diseases in the world; because of that it occupies the main position in concern of researchers. The main aim of this article is to search for a safe drug from natural sources, to be used for treatment of ulcers without side effects. Several reports showed that a large number of medicinal plants from Convolvulus species possess antiulcer activity in addition to other activities.
Our goal is to collect and compare published data in the last 28 reviews concerning the natural products and the synthetic ones from Convolvulus species and other families in the treatment of this disease and other diseases; in addition a quick screening for phytochemical and biological activities of different Convolvulus species are reported.
Keywords: Antiulcerogenic activity; Convolvulus; Peptic ulcer; Natural products
Introduction
Family Convolvulaceae contains a large number of important plants which are used in treatment of various diseases elsewhere such as; headache, constipation, rheumatism, diabetes and skin infection [1]. Members of this family mainly contain phenolic, tropane alkaloids [2], flavanoids and coumarins [3].The largest genus of family Convolvulaceae is Convolvulus; it comprises 250 species present as trees, shrubs or herbs [4]. Many Convolvulus species are valuable ornamentals, medicinal and food crops [5]. They possess cytotoxic [6], antioxidant, anti-inflammatory and antiulcer activities [3]. In addition they can be used in treatment of coughs and asthma [1].
Peptic ulcer is one of the most common chronic gastrointestinal disorders in modern era. Now it has become a common global health problem affecting a large number of people worldwide and it still a major cause of illness and deaths [7]. There are different classes of drugs are used in the treatment of peptic ulcer, most of them exhibits serious side effects like; arrhythmias, gynaecomastia, arthralgia, hypergastrinemia [8], impotence, haemopoeitic changes [7], nausea, abdominal pain, constipation and diarrhea [9].
Plant secondary metabolites have been in use for centuries to cure various ailments. The use of natural medicine in the treatment of peptic ulcer is an absolute requirement of our effort [10]. Traditional medicine has proved to be clinically effective and relatively less toxic than the existing drugs and also reduces the offensive factors serving as a tool in the prevention of peptic ulcer [11].
Plants with anti ulcerogenic activity were used either as row materials which obtained by extraction with various solvents or as individual isolated compounds. Many solvents have been used to extract active materials from plants such as; alcohol (ethanol or methanol), ether, chloroform, ethyl acetate, n-butanol and water [12].
Peptic ulcer is one of the most serious gastrointestinal disorders which occupy the main position in concern of researchers [13], it can be caused by many factors such as; stress [14], Helicobacter pylori [15], acid–pepsin secretion [16], nonsteroidal anti-inflammatory drug [17], cigarettes [18], nutritional deficiencies [19] as well as alcohol [20]. It is a lesion in the gastrointestinal tract that usually occurs in the stomach and duodenum and is characterized by mucosal damage [21].
Natural anti-ulcer products
Peptic ulcer therapy has undergone many steps over the past few years and both herbal and synthetic drugs are now available offering newer and better options for treatment of peptic ulcer [8]. Many synthetic drugs have been used in the treatment of gastric ulcers such as; antiacids, anticholinergics, proton pump inhibitors and H2- receptor antagonists [22]. However, these drugs are expensive [21] and showed an incidence of relapses, drug interactions and side effects [23] thereby limiting their usefulness. The search for an ideal anti-ulcer drug with new and novel molecules has also been extended to herbal drugs and their isolated compounds as alternative ways for treatment of ulcers that afford better protection [24], clinically effective, possess good tolerability even in higher doses [25] and lack of side effects compared to synthetic drugs [26].
Recently, plant extracts are considered to be one of the most attractive sources for developing new drugs and have been shown immense potential results in the treatment of gastric ulcers [27,28]. The literature reported many medicinal plants with antiulcer activity which is used as row materials (obtained by extraction with solvents) or as individual isolated compounds [29]. Some plants and isolated compounds with antiulcerogenic activity are reported in (Table 1).

Convoluvuls species
The Convolvulus is a genus of flowering plants in Convolvulaceae family. This genus showed that it contains phenolic, tropane alkaloids [169], sterols, resin and sugars [170]. It has been reported that it exhibits many activities such as; asthma, jaundice [171], cytotoxic effects [172], anti-cancer activity [173] and antioxidant activity [169]. Although nothing was traced about the plant under investigation, reviewing the current literature there are many of the species of this genus were studied for their biological activity and isolated compounds.
Phytochemical contents of Convolvulus species: Studies showed that the convolvulus species contains phenolics [174], saponins, steroids, alkaloids, proteins, lipids [175], polyphenolic compounds [5], flavonoid [11,176], coumarins [177,178], volatile oil, carbohydrates [179], tannins, cardiac glycosides [180,181], triterpenoids [182], lactones and amino acids [183].
Biological activities of Convolvulus species: Reviewing the previous literatures; we found that Convolvulus species possess various biological activities such as; cytotoxic activity, stimulating effects [175], antimicrobial activity [184], anticonvulsant activity, antioxidant activity [1,176,185], neuroprotective effect [186], antimicrobial activity [187,178], anti-inflammatory, anti-nociceptive, antipyretic activities [11], laxative effect [5], scavenging activity [169], antibacterial, antiulcer [177], antistress [177], antidysenteric, hypolipidaemic, larvicidal, anti-mosquito properties and useful as a memory enhancer [182], antidiarrhoeal effect [183], anti-cancer agents [188], anti-angiogenesis [172], CNS-depressant activity [189], antifeedant [182], antidiabetic activity [190] and inhibition of platelet aggregation [191].
Isolated compounds from Convolvulus species: Many compounds have been isolated and reported in literatures from Convolvulus species such as; p-hydroxybenzoic acid, syringic acid and vanillin [174], quercetin, quercetin 3-O-rutinoside and quercetin-7-O-rhamnoside, ferulic acid [1], p-coumaric acid [192], 3-(2-butoxy-3-caffeoyl-1-hydroxycyclobutyl)-3-hydroxypropanoic acid and 4-O-(4'-carboxymethyl-2',4',6'-trihydroxycyclohexyl) vanillic acid [169], scopoletin, ß-sitosterol and ceryl alcohol [177], Phytosterol [179], cuscohygrine [193], choline hydrochloride, betain hydrochloride [178], umbeliferone, asculetin, scopoline, kaempferol- 3-rhamnoside [194], 29-oxodotriacontanol, tetratriacontanoic acid [182], Pseudotropine and hygrine [173].
MEDLINE Search
To collect the data which support this idea we performed a systematic review using PubMed, Google, Science direct and MEDLINE database. All English-language articles published between 1964 and 2012 were searched using the terms ‘antiulcerogenic’, ‘anti-ulcer’, ‘gastroprotective’, ‘gastric antiulcerogenic’, ‘peptic ulcer’, ‘Convolvulus’, ‘natural products’, ‘Helicobacter pylori’, ‘plant extracts’, ‘synthetic anti-ulcer compounds’. Plants names, families and authorities were confirmed using https://www.tropicos.org/ and https://www.theplantlist.org/ sites.
Conclusion
Peptic ulcer can be considered as the most wide distributed diseases and a lot of work has been reported in literature talking about this disease. Convolvoulus family contains many species mentioned in literature have a high biological activity as anti-ulcerogenic. Some researcher used the total extract in treatment of ulcer; others studied the effect of the isolated compounds.
Reviewing the last 28 years, many researchers from different countries focused on the scientific proof of the activity of this family species. Scientists found that the amount extracted from natural sources is too much little to be economically benefited in industrial or medicinal fields, so they try to mimic the isolated natural compounds synthetically, studying the biological activity and the side effects of the synthetic compounds.
