Mulinum crassifolium Phil. (Apiaceae) is an endemic shrub from Chile commonly used as infusion in traditional medicine to treat diabetes, bronchial and intestinal disorders and stomach ailments, including ulcers. From the EtOAc extract of this plant, the new mulinane-type diterpenoids 3 and 5 were isolated along with three known diterpenoids. The gastroprotective effect of the infusion of the plant was assayed to support the traditional use and a fast HPLC analysis using high resolution techniques was performed to identify the bioactive constituents. The EtOAc extract and the edible infusion showed gastroprotective effect at 100 mg/kg in the HCl/EtOH induced gastric ulcer model in mice, reducing lesions by 33% and 74%, respectively. Finally, a metabolomic profiling based on UHPLC-ESI-MS/HRMS of the edible infusion was performed and thirty-five compounds were tentatively identified including quercetin, caffeic acid, apigenine glucoside, p-coumaric acid, chlorogenic acids, and caffeoylquinic acids, which have been associated previously with gastroprotective and antiulcer properties. This scientific evidence can support the contribution of polyphenols in the gastroprotective activity of the edible infusion of this plant, and can validate at least in part, its ethnopharmacological use.

Chromobacterium violaceum, Gram-negative bacteria species found in tropical regions of the world, produces a distinct deep violet-colored pigment called violacein. In the present study, we investigated whether violacein can promote a gastroprotective effect and verified the possible mechanisms involved in this action. For this study, an indomethacin-induced gastric ulcer rat model was used. The roles of biomolecules such as MPO, PGE2, pro- and anti-inflammatory cytokines, growth factors, caspase-3, NO, K+ATP channels, andα2-receptors were investigated. Violacein exhibited significant gastroprotective effect against indomethacin-induced lesions, while pretreatment with L-NAME and glibenclamide (but not with NEM or yohimbine) was able to reverse this action. Pretreatment with violacein also restored cNOS level to normal and led to attenuation of enhanced apoptosis and gastric microvascular permeability. Our results suggest that violacein provides a significant gastroprotective effect in an indomethacin-induced ulcer model through the maintenance of some vital protein molecules, and this effect appears to be mediated, at least in part, by endogenous prostaglandins, NOS, K+ATP channel opening, and inhibition of apoptosis and gastric microvascular permeability.

Leaves from Flabellaria paniculata Cav (Malpighiaceae) are used in traditional medicine for wound dressing, and to treat ulcers and inflammation in Nigeria. The present study evaluates the gastroprotective activity of the ethyl acetate fraction of the methanolic leaf extract and reports on the chemical constituents from the fraction. The methanolic crude extract and solvent fractions (100 mg/kg, PO) were screened using an ethanol-induced ulcer model. The activity of the most active EtOAc fraction (25, 50, and 100 mg/kg, PO) was further evaluated in indomethacin and pylorus ligation-induced ulcer models. The EtOAc fraction was chromatographed and chemical structures of the isolated compounds were elucidated by nuclear magnetic resonance spectroscopy. The MeOH extract of F. paniculata and EtOAc fraction from this extract displayed significant gastroprotective effects. Two triterpenoids (friedelin and friedelinol), two steroids (sitosterol and sitosterol-β-d-glucoside), and a flavonoid glycoside (kaempferol-3- O-α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside) were identified from the EtOAc fraction. This is the first report on the isolation of these compounds from the plant. The identified compounds could be responsible in part for the observed gastroprotective effect of the EtOAc fraction.

Gastroprotective Action

Lycium minutifolium J. Remy (Solanaceae) is commonly used as an infusion in traditional medicine to treat stomach pain, meteorism, intestinal disorders, stomach ailments, and other severe problems including prostate cancer and stomach cancer. From the EtOAc extract of L. minutifolium bark five known metabolites were isolated using chromatographic techniques. The gastroprotective effects of the EtOAc fraction and edible infusion extract of the bark were assayed on the hydrochloric acid (HCl)/EtOH induced gastric ulcer model in mice to support the traditional use of the plant. The EtOAc extract and the edible infusion showed gastroprotective effect at dose of 100 mg/kg reducing lesions by 31% and 64%, respectively. The gastroprotective action mechanisms of the edible infusion at a single oral dose of 100 mg/kg were evaluated suggesting that prostaglandins, sulfhydryl groups, and nitric oxide are involved in the mode of gastroprotective action. The UHPLC analysis coupled to high-resolution mass spectrometry of the edible infusion showed the presence of twenty-three compounds. Our results can support the gastroprotective properties of the edible infusion extract, and at least can validate in part, the ethnopharmacological uses of the plant.

Angelicae Pubescentis Radix (AP), as a traditional Chinese medicine (TCM), has been used for thousands of years in China. In this paper, the botany, traditional use, phytochemistry, analytical methods, quality control, pharmacological effects, and toxicity of AP were reviewed. It can provide a reference for the further research and lay a foundation for the rational clinical application of AP. The relevant information on AP was collected from scientific databases (such as Baidu Scholar, CNKI, Google Scholar, PubMed, Science Direct, Web of Science, and SciFinder Scholar), Chinese herbal classics, Chinese Pharmacopoeia, PhD and MSc dissertations, and so on. The components which have been isolated and identified in AP include coumarins, volatile oils, organic acids, terpenes, polysaccharides, flavonoids, sterols, and trace elements. Most of them were analyzed by HPLC and GC. A pharmacological study shows that the AP has extensive pharmacological effects, including anti-inflammatory, antirheumatism, sedative and hypnotic, neuroprotection, antioxidation, antitumor, and allergy, and it is widely used in the treatment of the rheumatoid arthritis, knee osteoarthritis, lumbar disc, ankylosing spondylitis, headaches, stroke hemiplegia, Alzheimer’s, and arrhythmia. AP is a valuable natural medicinal plant. So far, significant advances have been made in phytochemistry and pharmacology. Some traditional uses have been demonstrated by modern pharmacology. However, the chemical components and pharmacological effects of AP are complex and varied, and there are different standards for the evaluation of its quality and efficacy. The mechanism of action, the structure-activity relationship among the components, and the potential synergistic and antagonistic effects remain to be studied. At the same time, there are few studies on the specific compounds related to its pharmacodynamics. In order to better develop and utilize AP, we should establish a more reasonable, reliable, and accurate quality control standard and focus on the study of bioactive constituents and the demonstration of their mechanism of action.

Tannins are polyphenolic compounds historically utilized in textile and adhesive industries, but also in traditional human and animal medicines or foodstuffs. Since 20th-century, advances in analytical chemistry have allowed disclosure of the chemical nature of these molecules. The chemical profile of extracts obtained from previously selected species was investigated to try to establish a bridge between traditional background and scientific data. The study of the chemical composition of these extracts has permitted us to correlate the presence of tannins and other related molecules with the effectiveness of their apparent uses. The revision of traditional knowledge paired with scientific evidence may provide a supporting background on their use and the basis for developing innovative pharmacology and food applications based on formulations using natural sources of tannins. This traditional-scientific approach can result useful due to the raising consumers’ demand for natural products in markets, to which tannin-rich extracts may pose an attractive alternative. Therefore, it is of interest to back traditional applications with accurate data while meeting consumer’s acceptance. In this review, several species known to contain high amounts of tannins have been selected as a starting point to establish a correlation between their alleged traditional use, tannins content and composition and potential bioaccessibility.

The gastroprotective effect of methanolic extract of Lagerstroemia indica and the possible mechanisms used to investigated the ulcer activity through indomethacin-induced ulcer model. Method: male Wistar rats were divided into three groups: (normal control, n=6), (standard omeprazole group, n=6) and (extract group, n=6). Each of control, omeprazole and extract were administered orally to the rats daily for 21 days before the induction of ulcer with the help of indomethacin. On the 21 days indomethacin was administered with single oral dose (20mg/kg). Four hours later after the administration of indomethacin dose treatment, the rats were sacrificed and gastric tissue was taken for histopathological investigation for the calculation of pH, ulcer inhibition, ulcer index. The observation significantly increased (p < 0.01) value that reduced the ulcer by the treatment with Lagerstroemia indica. Result: The result indicates the antiulcer effect of the Lagerstroemia indica extracts showed significant effect during comparision with control and standard group. The data of study revealed that the extracts of Lagerstroemia indica proved to show control over the model of indomethacin-induced gastric ulceration which gives potent activity against ulceration.

Abstract Tropaeolum tuberosum, commonly known as Mashua, is an herbal remedy used in traditional Andean medicine for the relief of kidney and bladder pain, as well as contusions. This study aimed to evaluate the fractions and isolated compounds from T. tuberosum with analgesic activity mediated by the transient receptor potential vanilloid-1 receptor. A bioguided phytochemical analysis based on NMR/MS was performed to identify the compounds of the n-heptane fractions from samples of purple tubers of T. tuberosum. The transient receptor potential vanilloid-1 agonist and antagonist activity were assessed through the measurement of intracellular Ca2+ in HEK001 cells. The chemical structure determination led to the identification of two alkamides: N-(2-hydroxyethyl)-7Z,10Z,13Z,16Z-docosatetraenamide (1) and N-oleoyldopamine (2). Both compounds induced increased intracellular calcium flow with IC50 values of 3.2 nM and 7.9 nM, respectively, thus activating the transient receptor potential vanilloid-1 receptor. Our research is the first report to show that these two compounds isolated from T. tuberosum can act as agonists of the transient receptor potential vanilloid-1 receptor, providing scientific evidence for the traditional use of this species in pain relief.

Calophyllum inophyllum L. (Calophyllaceae), locally called “tamanu” in French Polynesia, is an evergreen pantropical tree growing mostly along the seashores. Its barks, leaves, and fruits are still used in traditional medicine. The oil expressed from the nuts has been also traditionally used. Tamanu oil is topically applied on skins as well as mucous membrane lesions. This oil is especially recommended to heal all kinds of skin ailments. Bioassays and different assessments of Tamanu oil revealed numerous biological activities (antioxidant, anti-inflammatory, antibacterial, wound healing…), so bringing scientific evidence of beneficial effects of this oil on human skin healing. Such biological properties may explain the use of tamanu oil as an active cosmetic ingredient recorded as “Calophyllum inophyllum seed oil” by the INCI (International Nomenclature of Cosmetic Ingredients). Most of the bioactive properties of tamanu oil are attributed to oil composition including the presence of resinous compounds in tamanu oil beside common fatty acids, which constitutes a unique characteristic of this healing oil. Actually, resinous part of tamanu oil is known to contain bioactive secondary metabolites mostly constituted by neoflavonoids including pyranocoumarin derivatives. Herein, chemical constituents and biological properties of tamanu oil are presented with a focus of its traditional use inspiring modern valuations related to cosmetic field.

Background: Peptic ulcer disease remains endemic in our society affecting about four million people every year worldwide. Hannoa klaineana is used traditionally in the treatment of various gastrointestinal diseases including ulcer.Aim: This study aims at evaluating the gastroprotective effect of ethylacetate fraction of the leaves of Hannoa klaineana (Simaroubaceae).Methods: The gastroprotective effect of ethylacetate fraction of the Hannoa klaineana (50, 100 and 200mg/kg b.wt) was evaluated using aspirin and histamine induced ulcer models.Results: In aspirin-induced ulcer model, the ethylacetate fraction of the Hannoa klaineana demonstrated significant (p<0.001) decreased in mean ulcer index with the maximum protective effect (99.84%) at 200 mg/kg against the gastric damages. While histamine-induced ulcer model, the solvent fraction significantly (p<0.001) decreased mean ulcer index with the protective effect up to 99.83% against the gastric lesions. In both models, a significant (p<0.001) increased in pH value coupled with significant (p<0.001) decreased in gastric volume, free and total acidity in rats pre-treated with varying doses of the ethylacetate fraction was found.Conclusion: The mechanism of gastroprotective effects of ethylacetate fraction of the Hannoa klaineana could be attributed to its ability to stimulate prostaglandins secretion or possess prostaglandins like-substances or suppression of histamine-induced vasospastic effect and gastric secretion.
