A study on composition and hypolipidemic effect of dietary fibre from some plant foods

In vivo biological screening of extract and bioactive compound from Ficus benghalensis L. and their in silico molecular docking analysis

BACKGROUND

Ficus benghalensis has been used by local health care practitioners to treat pain, inflammation, rheumatism, and other health issues.

OBJECTIVE

In this study, the crude extract and diverse fractions, along with the isolated compound of F. benghalensis were examined for their roles as muscle relaxants, analgesics, and sedatives.

METHODS

The extract and isolated compound 1 were screened for muscle-relaxant, analgesic, and sedative actions. The acetic acid-mediated writhing model was utilized for analgesic assessment, the muscle relaxant potential was quantified through traction and inclined plan tests, and the open field test was applied for sedative effects.

RESULTS

The extract/fractions (25, 50, and 100 mg/kg) and isolated compounds (2.5, 5, 10, and 20 mg/kg) were tested at various doses. A profound (p< 0.001) reduce in the acetic acid-mediated writhing model was observed against carpachromene (64.44%), followed by ethyl acetate (60.67%) and methanol (58.42%) fractions. A marked (p< 0.001) muscle relaxant activity was noticed against the isolated compound (71.09%), followed by ethyl acetate (66.98%) and methanol (67.10%) fractions. Regarding the sedative effect, a significant action was noted against the isolated compound (71.09%), followed by ethyl acetate (66.98%) and methanol (67.10%) fractions. Furthermore, the binding modes of the isolated compounds were explored using molecular docking. The molecular docking study revealed that the isolated compound possessed good binding affinity for COX2 and GABA. Our isolated compound may possess inhibitory activity against COX2 and GABA receptors.

CONCLUSION

The extract and isolated compounds of Ficus benghalensis can be used as analgesics, muscle relaxants, and sedatives. However, detailed molecular and functional analyses are essential to ascertain their function as muscle relaxants, analgesics, and sedatives.

Therapeutic potential of Ficus benghalensis in thromboembolic disorders

Ficus benghalensis L. (FB) is a popular plant described in the Indian system of medicine. Traditionally, it is indicated in the treatment of diseases like diabetes mellitus, dysentery, leucorrhoea, menorrhagia, skin disease, rheumatism, inflammatory diseases, blood disorders. This paper accentuates the anti-thrombotic action of FB based on the properties like anti-coagulant, platelet-antiaggregatory, anti-atherogenic hypotensive, hypolipidemic, anti-oxidant, anti-inflammatory and immunomodulatory. All the available data pertaining to FB has been searched in the scientific databases, including PubMed, Google Scholar, ScienceDirect and Scopus. FB is a rich lode of organic compounds such as phenols, flavonoids, alkaloids, tannins, terpenoids and steroids. The various studies show that these phytochemical constituents exhibit wide range of anti-thrombotic actions such as anticoagulant, platelet anti-aggregatory, anti-atherogenic, hypolipidemic, hypotensive, anti-inflammatory, and antioxidant. Various studies (in vitro and in vivo) confirm the potential anti-thrombotic benefit of FB due to the presence of chemical structures that have proven to be effective in thromboembolic conditions. These evidences may benefit in new drug development to treat varied thromboembolic conditions which will not only be cost effective but may allay the fear of side effects.

New Horizons for the Study of Dietary Fiber and Health: A Review

Dietary fibre has been consumed for centuries with known health benefits, but defining dietary fibre is a real challenge. From a functional perspective, dietary fibre is described as supporting laxation, attenuating blood glucose responses and assisting with cholesterol lowering. The problem is different types of dietary fibre have different effects, and new effects are increasingly observed, such as the influence on gut microbiota. Thus, a single definition may need to be described in more generic terms. Rather than being bound by a few functional definitions, we may need to embrace the possibilities of new horizons, and derive a working definition of dietary fibre based on a set of conceptual principles, rather than the limited definitions we have to date. To begin this process, a review of individual fibre types and their physiological effects would be helpful. Dietary fibre is a complex group of substances, and there is a growing interest in specific effects linked to fibre type. Different fractions of dietary fibre have different physiological properties, yet there is a paucity of literature covering the effects of all fibres. This paper describes a range of individual fibre types and identifies gaps in the literature which may expose new directions for a working definition of dietary fibre.

Design of experiment approach for the process optimisation of microwave assisted extraction of lupeol from Ficus racemosa leaves using response surface methodology

INTRODUCTION

Triterpenoids are a group of important phytocomponents from Ficus racemosa (syn. Ficus glomerata Roxb.) that are known to possess diverse pharmacological activities and which have prompted the development of various extraction techniques and strategies for its better utilisation.

OBJECTIVE

To develop an effective, rapid and ecofriendly microwave-assisted extraction (MAE) strategy to optimise the extraction of a potent bioactive triterpenoid compound, lupeol, from young leaves of Ficus racemosa using response surface methodology (RSM) for industrial scale-up.

MATERIAL AND METHOD

Initially a Plackett-Burman design matrix was applied to identify the most significant extraction variables amongst microwave power, irradiation time, particle size, solvent:sample ratio loading, varying solvent strength and pre-leaching time on lupeol extraction. Among the six variables tested, microwave power, irradiation time and solvent-sample/loading ratio were found to have a significant effect (P < 0.05) on lupeol extraction and were fitted to a Box-Behnken-design-generated quadratic polynomial equation to predict optimal extraction conditions as well as to locate operability regions with maximum yield.

RESULTS

The optimal conditions were microwave power of 65.67% of 700 W, extraction time of 4.27 min and solvent-sample ratio loading of 21.33 mL/g. Confirmation trials under the optimal conditions gave an experimental yield (18.52 µg/g of dry leaves) close to the RSM predicted value of 18.71 µg/g.

CONCLUSION

Under the optimal conditions the mathematical model was found to be well fitted with the experimental data. The MAE was found to be a more rapid, convenient and appropriate extraction method, with a higher yield and lower solvent consumption when compared with conventional extraction techniques.

Clinical study on erectile dysfunction in diabetic and non-diabetic subjects and its management with Ficus relegiosa Linn

Healthy sexual functioning plays an essential role in maintaining the harmony and happiness in marital life. It provides a media to express love, which is the base for all sorts of creative activities. The absence of this function hampers the marital relationship, leading to frustration and, sometimes, ending in divorce, and causes inadequacy in performing the routine duties. In this study, 53 patients having diabetes mellitus were surveyed to find out the incidence of erectile dysfunction (ED). Considering the high prevalence of the disease and the need to look for alternative medicine, a clinical trial on 44 patients of ED was carried out. These patients were divided into two main groups: diabetic and non-diabetic, and were further divided into two subgroups as trial group and placebo group. In the trial group, Ashvattha Kshirpaka prepared with 10 g powder of its root bark, stem bark, fruit and tender leaf buds was given twice a day. In both the diabetic and the non-diabetic subjects, Ashvattha provided encouraging results on ED as well as on seminal parameters in comparison to the placebo.

Phytopharmacology of Ficus religiosa

Herbs have always been the principal form of medicine in India. Medicinal plants have curative properties due to the presence of various complex chemical substances of different composition, which are found as secondary plant metabolites in one or more parts of these plants. Ficus religiosa (L.), commonly known as pepal belonging to the family Moraceae, is used traditionally as antiulcer, antibacterial, antidiabetic, in the treatment of gonorrhea and skin diseases. F. religiosa is a Bo tree, which sheltered the Buddha as he divined the “Truths.” The present review aims to update information on its phytochemistry and pharmacological activities.

Indian herbs and herbal drugs used for the treatment of diabetes

Traditional Medicines derived from medicinal plants are used by about 60% of the world’s population. This review focuses on Indian Herbal drugs and plants used in the treatment of diabetes, especially in India. Diabetes is an important human ailment afflicting many from various walks of life in different countries. In India it is proving to be a major health problem, especially in the urban areas. Though there are various approaches to reduce the ill effects of diabetes and its secondary complications, herbal formulations are preferred due to lesser side effects and low cost. A list of medicinal plants with proven antidiabetic and related beneficial effects and of herbal drugs used in treatment of diabetes is compiled. These include, Allium sativum, Eugenia jambolana, Momordica charantia Ocimum sanctum, Phyllanthus amarus, Pterocarpus marsupium, Tinospora cordifolia, Trigonella foenum graecum and Withania somnifera. One of the etiologic factors implicated in the development of diabetes and its complications is the damage induced by free radicals and hence an antidiabetic compound with antioxidant properties would be more beneficial. Therefore information on antioxidant effects of these medicinal plants is also included.

Traditional uses, phytochemistry and pharmacology of Ficus religiosa: a review

ETHNOPHARMACOLOGICAL RELEVANCE

Ficus religiosa L. (Moraceae) has been extensively used in traditional medicine for a wide range of ailments of the central nervous system, endocrine system, gastrointestinal tract, reproductive system, respiratory system and infectious disorders.

AIM OF THE REVIEW

To comprehend the fragmented information available on the botany, traditional uses, phytochemistry, pharmacology and toxicology of F. religiosa to explore its therapeutic potential and future research opportunities.

MATERIALS AND METHODS

All the available information on F. religiosa was collected via electronic search (using Pubmed, SciFinder, Scirus, Google Scholar, Agricola and Web of Science) and a library search.

RESULTS

Ethnomedical uses of F. religiosa are recorded throughout South Asia, where it has been used for about 50 types of disorders. Phytochemical research had led to the isolation of phytosterols, amino acids, furanocoumarins, phenolic components, hydrocarbons, aliphatic alcohols, volatile components and few other classes of secondary metabolites from F. religiosa. Fresh plant materials, crude extracts and isolated components of F. religiosa showed a wide spectrum of in vitro and in vivo pharmacological activities like, antidiabetic, cognitive enhancer, wound healing, anticonvulsant, anti-inflammatory, analgesic, antimicrobial, antiviral, hypolipidemic, antioxidant, immunomodulatory, antiasthmatic, parasympathetic modulatory, esterogenic, antitumor, antiulcer, antianxiety, antihelmintic, endotheilin receptor antagonistic, apoptosis inducer and hypotensive.

CONCLUSIONS

F. religiosa emerged as a good source of traditional medicine for the treatment of asthma, diabetes, diarrhea, epilepsy, gastric problems, inflammatory disorders, infectious disorders and sexual disorders. Although many of the experimental studies validated its traditional medicinal uses, but employed uncharacterized crude extracts. Thus, it is difficult to reproduce the results and pinpoint the bioactive metabolite. Hence, there is a need of phytochemical standardization and bioactivity-guided identification of bioactive metabolites. The results of few pharmacological studies and bioactive metabolites already reported in F. religiosa warrant detailed investigation for its potential against cancer, cardiovascular disorders, neuroinflammatory disorders, neuropsychiatric disorders, oxidative stress related disorders and parasitic infections. The outcome of these studies will further expand the existing therapeutic potential of F. religiosa and provide a convincing support to its future clinical use in modern medicine.

Traditional herbal medicine in far-west Nepal: a pharmacological appraisal

BACKGROUND

Plant species have long been used as principal ingredients of traditional medicine in far-west Nepal. The medicinal plants with ethnomedicinal values are currently being screened for their therapeutic potential but their data and information are inadequately compared and analyzed with the Ayurveda and the phytochemical findings.

METHODS

The present study evaluated ethnomedicinal plants and their uses following literature review, comparison, field observations, and analysis. Comparison was made against earlier standard literature of medicinal plants and ethnomedicine of the same area, the common uses of the Ayurveda and the latest common phytochemical findings. The field study for primary data collection was carried out from 2006-2008.

RESULTS

The herbal medicine in far-west Nepal is the basis of treatment of most illness through traditional knowledge. The medicine is made available via ancient, natural health care practices such as tribal lore, home herbal remedy, and the Baidhya, Ayurveda and Amchi systems. The traditional herbal medicine has not only survived but also thrived in the trans-cultural environment with its intermixture of ethnic traditions and beliefs. The present assessment showed that traditional herbal medicine has flourished in rural areas where modern medicine is parsimoniously accessed because of the high cost and long travel time to health center. Of the 48 Nepalese medicinal plants assessed in the present communication, about half of the species showed affinity with the common uses of the Ayurveda, earlier studies and the latest phytochemical findings. The folk uses of Acacia catechu for cold and cough, Aconitum spicatum as an analgesic, Aesculus indica for joint pain, Andrographis paniculata for fever, Anisomeles indica for urinary affections, Azadirachta indica for fever, Euphorbia hirta for asthma, Taxus wallichiana for tumor control, and Tinospora sinensis for diabetes are consistent with the latest pharmacological findings, common Ayurvedic and earlier uses.

CONCLUSIONS

Although traditional herbal medicine is only a primary means of health care in far-west Nepal, the medicine has been pursued indigenously with complementing pharmacology and the Ayurveda. Therefore, further pharmacological evaluation of traditional herbal medicine deserves more attention.

Anti-diabetic potential of alkaloid rich fraction from Capparis decidua on diabetic mice

ETHNO PHARMACOLOGICAL RELEVANCE

Capparis decidua (CD) is a xerophytic shrub, found widely in the western parts of India, Pakistan and some of the Asian countries. The dried fruits are used as an ingredient in anti-diabetic compositions.

AIM OF THE STUDY

The present study was carried out to test the effect of alkaloid rich (AR) fraction from this plant in the management of diabetes.

MATERIALS AND METHODS

Streptozotocin-induced diabetic mice were treated with the AR fraction for 28 days. On completion of the treatment, a range of parameters were tested including oral glucose tolerance test (OGTT), blood lipid profile, expression patterns of various glucose homeostatic enzyme genes and their activities.

RESULTS

Treatment of diabetic mice with AR fraction for 28 days significantly inhibited the acute elevation of blood glucose level during OGTT and also reduced total cholesterol (TC) and triglyceride (TG) content (p<0.05). Activity of glucose-6-phosphatase (G6Pase) was attenuated by 44%, also liver and muscle glycogen content showed significant improvement (p<0.05). The expression of different target genes like G6Pase, phosphoenolpyruvate carboxykinase (PEPCK), aldose reductase and tumor necrosis factor-alpha (TNF-alpha) showed significant reduction whereas glucose transporter-4 (Glut-4), peroxisome proliferator activated receptor-gamma (PPAR-gamma) and glucokinase (GK) improved remarkably.

CONCLUSIONS

AR fraction showed promising results in terms of anti-diabetic activities establishing its candidacy for further purification and characterization of the individual alkaloids, in order to understand their mechanism of action.

The influence of teent (Capparis decidua) on human plasma triglycerides, total lipids and phospholipids

Teent is an unripe fruit of Ker (Capparis decidua) a xerophytic bush. It contains 15.1% protein and 42.88% fibre. Being a rich source of fibre, the process for preparation of teent powder and other recipes were standardized for feeding hyperlipidemic subjects. The diet of 15 hyperlipidemic adults (40-60 yrs.) was supplemented with teent for three months and plasma triglycerides, total lipids and phospholipids were analysed before and at the end of the experiment. Significant reductions in plasma triglycerides, total lipids and phospholipids concentration were noticed.
