Ultrasonic Assisted Extraction

The increase in durian production results in the accumulation of durian peel waste. The bioactive component of durian peel has the potential to be used as an antioxidant. Thus, there is a need to carry out an extraction process to obtain  bioactive compounds from durian peel. However, conventional extraction methods cause damage to phenolic compounds due to oxidation, hydrolysis and ionization reactions during the extraction process. Therefore, durian peel extraction was carried out using ultrasonic assisted extraction method (UAE) in this study. The purpose of this study was to investigate the effect of varying ratios of durian peel to ethanol solvents and extraction time on the yield, total phenolics content, total flavonoids content and antioxidant activity. The results of the research data were analyzed using a two-factor completely randomized design, which included variations of the ratio of durian peel to ethanol solvents and extraction time The Duncan’s New Multiple Range Test (DNMRT) was carried out as a follow up test to determine the differences in each treatment at a significance level of 0.05. The results showed that the best treatment for peel extraction using ultrasonic assisted extraction was a 1: 9 ratio of durian peel to ethanol at an extraction time of 20 minutes. The extraction of durian peel under this condition gave the highest yield of 12.77 ± 0.16%, antioxidant activity (IC50) of 38.33 ± 0.12 ppm, total phenolic content of 63.30 ± 0.08 mgGAE / g and total flavonoids content of 47.53 ± 0.48 mgQE / g. In addition, total phenolics content and total flavonoid content showed a strong correlation to the antioxidant activity of durian peel extract.

The increasing interest in powerful biological activity of secondary metabolites outlined the necessity of determining their contents in medicinal plants. In the last few years, there has been an exponential growth in the field of herbal medicine and gaining popularity both in developing and developed countries because of their natural origin and less side effects. Clematis heynei (C. heynei, Ranunculaceae) is commonly known as Deccan clematis, Murhar, Morvel, Ranjaee and it is a somewhat woody climber very sparsely distributed in deciduous forests of Western Ghats, India. In the Indian system of medicine ‘Ayurveda’ this plant is used to eliminate malarial fever and headache. Different plant parts were used for treating various diseases. Solanum virginianum L. (S. virginianum, Solanaceae, Solanum xanthocarpum Schrad. & H. Wendl.) is a diffuse and very prickly under shrub. It is found growing commonly in various regions of the world on sandy soils and is distributed throughout India. The plant is used traditionally to treat asthma, chest pain, leucoderma, scorpion bite, and sterility in women. The aim of the present study is to examine C. heynei and S. virginianum aerial parts of plant for phytochemical profile. Qualitative analysis of various phytochemical constituents and quantitative analysis of total phenolics and flavonoids were determined by the well-known test protocol available in the literature. Quantitative analysis of phenolic and flavonoids was carried out by Folins Ciocalteau reagent method and aluminium chloride method respectively. Phytochemical analysis revealed the presence of phenols, flavonoids, tannins, saponins, alkaloids, fixed oil and fats. The total phenolics content of methanolic and aqueous extract of C. heynei was (0.592, 0.292 mg/100mg), followed by flavonoids (1.371, 0.723mg/100mg) respectively. The total phenolics content of methanolic extract of S. virginianum was (0.345mg/100mg), followed by flavonoids (0.978mg/100mg). The present study concluded that the crude extract of C. heynei and S. virginianum is a rich source of secondary phytoconstituents which impart significant antioxidant potential. The findings of the present study will be helpful to phytochemists, pharmacologists and pharmaceutical industries.

AbstractAllelopathy is a vital ecological process that influences the dynamics of ecological succession, structure, and composition of plant communities. The present study aimed to evaluate a comparative account of allelopathic inhibitory actions in relation to total phenolic contents of aqueous extracts from seven traditionally used medicinal plants of India. Triticum aestivum and Cicer arietinum seedlings were used to test seed germination inhibition, seedling growth retardation and branch root sprouting inhibition. Allium cepa root tip cells were used for mitotic index inhibition and abnormal cell percentage analysis. The correlation between the total phenolics content and allelopathic activities was analyzed. The different extracts show the varied degree of allelopathic inhibitory activity. Out of these seven used extracts, Crinum asiaticum leaf extract (CaLAE) showed the highest allelopathic inhibitory action and it could reduce 94.3 and 79.59% root and shoot growth respectively at 96 h of treatment (1 mg/mL) and that was increased to 96.18 and 93.78% respectively with 2 mg/mL. The quantitative phytochemical analysis also revealed that CaLAE also possess relatively higher amounts of total phenolics. The growth retardation effects of the extract are in accordance with the mito-depression and increased chromosomal abnormality in A. cepa root tip cells. In conclusion, Crinum asiaticum may be considered as a prospective source of allelochemicals for plant growth regulation and a source of commercial herbicidal products.

This study was conducted to assess the physicochemical analysis, qualitative and quantitative phytochemical analysis and antioxidant activity of various solvent (n-hexane, ethyl acetate, ethanol, and water) extract obtained from Trichodesma indicum aerial parts. The physicochemical analysis was carried out using standard reported methods. Successive solvent extraction was carried out using n-hexane, ethyl acetate, and ethanol by the Soxhlet method, followed by maceration with water. Qualitative phytochemical screening was done using standard procedures. The extracts were analyzed for its total phenolic and total flavonoid contents by Folin - ciocalteu and Aluminium chloride colorimetric methods. For the extracts, antioxidant activity was screened using three different methods, 1, 1-diphenyl-2-picryl-hydrazyl assay, Nitricoxide assay, and Superoxide dismutase assay. Ascorbic acid has been used for antioxidant activity as a positive control. The percentage of inhibition was measured at various levels of concentration. The total ash, water-soluble ash, acid insoluble ash, sulfated ash, and the moisture content of the powdered drug was found to be 15.30, 07.50, 03.99, 21.00, 05.00%w/w. The qualitative phytochemicals found in the extracts are carbohydrates, proteins, and amino acids, flavonoids, phenols, phytosterols, saponins, tannins, and glycosides. The total phenolic and total flavonoid content of the extracts was found in the sequence of ethyl acetate > n-hexane > ethanol > aqueous. All the extracts demonstrated significant concentration-dependent antioxidant activity in DPPH assay, Nitric oxide assay, and Superoxide dismutase assay. The findings indicated that all solvent extracts of Trichodesma indicum have promising antioxidant activity and that could be the presence of phytochemicals present in the extract.
