“…Several substances were found in E. alsinoides , i.e., flavonols, flavonoids, alkaloids, cardiac glycosides, saponins, the alkanes pentatriacontane and triacontane, the phytosterol, β-sitosterol, phenolics, and tannins (Austin 2008; Naikawadi et al 2016) and the plant is used as brain and memory tonic herb (Naikawadi et al 2016), an anti-asthmatic, for treating uterine bleeding (Khare 2007), insanity, epilepsy and nervous debility (Auddy et al 2003), for antibacterial, antifungal, and antiulcer properties (Austin 2008). The most common uses for medicinal applications are from India and surrounding regions (Manandhar 1985; Auddy et al 2003; Khare 2007; Ayyanar and Ignacimuthu 2011; Naikawadi et al 2016), however uses from some other countries in Southeastern Asia were found such as Taiwan (Chen 2007), Vietnam, Thailand (Austin 2008), and Philippines (Quisumbing 1978). In the New World people also use E. alsinoides , but there are fewer reports than the Old.…”

BackgroundSeveral medicinal properties have been reported for plants in the genus Evolvulus, such as a brain tonic and antifungal from Evolvulus alsinoides, and a sedative and an anthelmintic from Evolvulus nummularius. Therefore, the correct identification of the source plants is critically important. The aim of this research was to investigate the micromorphology of two Evolvulus taxa used for herbal medicines compared with one worldwide ornamental species by using peeling, paraffin embedding, acetolysis, and SEM methods in order to support species identification.ResultsOur findings indicate that all taxa share several common features, such as a single layer of epidermis on both sides of leaf surfaces, sinuous anticlinal epidermal cell walls, anomocytic, paracytic or laterocytic stomata, and capitate glandular trichomes. Y-shaped hairs were found in two species but not in E. nummularius. Similarly, isobilateral mesophyll occurs in both E. alsinoides and Evolvulus glomeratus, but a dorsiventral mesophyll is present in E. nummularius. Stems consist of a single layer of epidermis, one to four chlorenchyma layers, one to seven layers of cortical cells and a bicollateral bundle with pith in the center. The seed coat epidermal cell shapes were irregular or polygonal with raised and undulated anticlinal boundaries, and folded or flattened to concave periclinal walls. Pollens of all taxa are monads, spheroidally shaped with 28–47 µm diameter, and 15-pantocolpate apertures type with microechinate ornamentation.ConclusionsAn identification key to species is constructed based on leaf anatomy and seed coat characters. This data can be used in other subjects such as pharmaceutical botany, organic chemistry, taxonomy and horticulture, in terms of species identification.

“…It was used to treat bowel problems and to promote conception. The entire plant was considered astringent and useful for treating hemorrhages and there are a variety of other medical applications, including as an adaptogenic, antiphlogistic, antipyretic, antiseptic, aphrodisiac, febrifuge, stomachic, tonic, vermifuge, against asthma, bronchitis, scrofula, syphilis and in “controlling night emissions” and also to promote wound healing [19-21]. …”

AimDiabetes mellitus (DM), a leading non communicable disease with multiple etiologies is considered as third greatest cause of death in all over the world. During DM, persistent hyperglycemia causes an increased production of free radicals via auto oxidation of glucose and non-enzymatic protein glycation which may lead to disruption of cellular functions and oxidative damage to membranes. The present study was designed to investigate the therapeutic effect of Evolvulus alsinoides on antioxidant activity in pancreas of experimental diabetes.MethodsThe antioxidant activities were done by using standard protocols. For histopathological analysis, the pancreatic tissues of all experimental groups were fixed with 10% formalin for 24 hrs then the samples were stained with haemotoxylin-eosin for the microscopic observation.ResultsOral administration of plant extract for 45 days resulted in significant antioxidant activity, increases the insulin level and also inhibits lipid peroxidation in pancreas of streptozotocin induced diabetic rats. The histopathological studies showed the normal histology of pancreas after treatment with plant extract and glibenclamide. This study showed that the administration of Evolvulus alsinoides to streptozotocin induced diabetic rats improves the antioxidant activity and remodel the structure of pancreas due to the presence of secondary metabolites like phenols, flavonoids, alkaloids, steroids, terpenoids and glycosides in the ethanolic extract of plant material.ConclusionFrom the present study, it can be concluded that the plant extract effectively reduced the oxidative stress induced by streptozotocin and potentially increased the insulin level. Hence, it can be used in the management of diabetes mellitus.

“…This species is called ‘Bléhé’. Infusions of leaves and flower are used to treat sensitive skin, asthma, skin diseases and catarrh (Austin ). Chemical constituents such as phenolic compounds (flavonoids, caffeic acid), triterpenoids (triacontane, pentatriacontane, β ‐sitosterol) and alkaloids (tropanic, pyrrolidinic…) had already been isolated from this species.…”

Screening of the antifungal activities of ten Guadeloupean plants was undertaken to find new extracts and formulations against superficial mycoses such as onychomycosis, athlete's foot, Pityriasis versicolor, as well as the deep fungal infection Pneumocystis pneumonia. For the first time, the CMI of these plant extracts [cyclohexane, ethanol and ethanol/water (1:1, v/v)] was determined against five dermatophytes, five Candida species, Scytalidium dimidiatum, a Malassezia sp. strain and Pneumocystis carinii. Cytotoxicity tests of the most active extracts were also performed on an HaCat keratinocyte cell line. Results suggest that the extracts of Bursera simaruba, Cedrela odorata, Enterolobium cyclocarpum and Pluchea carolinensis have interesting activities and could be good candidates for developing antifungal formulations.
