Background: Use of the indigenous, easily accessible leafy vegetable roselle (Hibiscus sabdariffa L.) for value addition is gaining impetus as its nutritive and nutraceutical compounds are exposed by investigations. In water extracts, we rely on decoction to pull constituents tough parts of plants: root, bark, and seeds. The extracts were subjected to further antioxidant and total phenolics content studies. Microwave drying preserves high phenolic compounds in G. pseudochina leaves. We found out that dry mass of the cultivated garden cress, taking into account both methods of the extraction and the dilutions of the extracts, was comparable in all the groups (Table 3).We observed no influence of algal extract concentration on Lepidium sativum dry weight. The MLM extract additionally contained pyrrolizidine alkaloids (PAs) at a low concentration. To provide technical support for the industrial production of fermented plant extract powder, the quality characteristics of fermented plant extract powder prepared by hot air-drying, spray drying, vacuum microwave drying, and freeze-drying are compared for an FPE product. These factors depend on plant parts used, genetic variation, geographical location, climatic conditions, collection period, drying methods… Microwave-dried G. pseudochina leaves contain a low content of pyrrolizidine alkaloids. Gireesh et al. When I use this method, I hang clothes hangers from a shower curtain rod, string, etc., and tie branches to the clothes hanger with thick rubber-coated garden ties.

Microwave drying preserves high phenolic compounds in G. pseudochina leaves. To make a decoction, simply simmer in water for a minimum of 20 minutes, though some decoctions could go for hours or even days. The extracts from plant tissue are a rich source of leadcompounds for nutraceutical or pharmaceutical applications 5. To study the utilization of plant phenolics for psoriatic treatment, the effects of the drying process, solvent extraction process and age of the leaves on the total phenolic content (TPC), total flavonoid content (TFC), crude extract and anti-oxidant activity were evaluated. 6. The effects of maltodextrin, soluble starch, and β-cyclodextrin as a drying agent on drying effect were studied. Artificial drying can be done with the help of artificial driers.

These steps are (1) lyophilisation, or freeze drying, and tissue disruption, (2) extraction in water or methanol, (3) purification of extract, typically by desulfation on DEAE Sephadex, and (4) separation and analysis of (desulfo)glucosinolates. Various methods, such as Maceration, Infusion, Percolation, Decoction, Digestion, Soxhlet extraction, Microwave assisted extraction, Ultrasound-assisted extraction, Accelerated solvent extraction and Supercritical fluid extraction are used for the plant samples extraction which are discussed in this article. CA content was increased with microwave drying. Ethanolic solvents have the most potential for phenolic recovery from G. pseudochina leaves. © 2018 Elsevier B.V. All rights reserved. The LC–MS/MS results revealed that 25% (v/v) and 99.9% (v/v) ethanol extracts of mixed-ages leaves dried using a microwave (MLM) contained phenolic acids, flavonoids, a xanthone derivative, a phenylpropanoid, a phenolic glycoside compound and a glycerol-phospholipid. Fermented plant extract (FPE) is a kind of plant functional food fermented by various microorganisms to make a beverage or other physical forms. 5 Howick Place | London | SW1P 1WG. For aromatic plants, hydro water and steam distillation), hydrolytic maceration followed by distillation, expression and effleurage (cold fat extraction) may be employed. G. pseudochina leaf extract has mild toxicity to keratinocyte cells. The results showed that freeze drying and microwave drying preserved high levels of TPC, TFC and anti-oxidant activity. Finally for each of the species fifteen separate extracts were prepared (three fresh plant extracts and twelve extracts of four drying methods). The solvent … Flowers of good quality and at slightly immature stage should be selected for drying. We use cookies to help provide and enhance our service and tailor content and ads. The extracts are made using carbon dioxide, which is compressed until it creates supercritical fluid. These steps are outlined in Fig. The results reported by these authors indicated that the powder containing gallic acid had a much higher glass transition temperature than the powder without phenolic content, being this variable strongly related to stickiness. FMZ201803), all of which enabled us to perform this study. 1 and discussed in more depth below. is a local herb that has been used as an anti-inflammatory agent. Process: Buds or trim are run through a series of … Direct steam distillation involves bubbling steam through the plant material and is suitable for aromatic plants with lower temperature needs. Ethanol was used instead of methanol because the former is a safer solvent for health product application. flavonoids and total antioxidants), the most suitable drying method was hot air at 180 °C, since it substantially increased all of them (76.8 mg gallic acid, 45.1mg catechin and 126 mg Trolox, all equivalent/g Stevia, respectively), with This process will reduce the drying time to several hours or minutes. method can shorten drying time but sometimes causes degradation of phytochemicals. https://doi.org/10.1016/j.indcrop.2018.04.020.

In a first step, the individual extracts and a combination of both, showing synergistic effects (Sl:Ca, 1:1), were microencapsulated by spray-drying using maltodextrin as the encapsulating material. Results show that spray-dried FPE powder has the highest bulk density, the smallest average particle size, while the FPE powder produced by freeze-drying has the best color and flavor, the highest content of key components including total sugar, soluble protein, vitamin C, total polyphenol content, and highest antioxidant capacity. The process must generally be simple, fast, economic, in compliance with the local regulation, effective and selective when needed. In this process plants are placed in the plates of drier on which warm air is blown. The common method that is followed in drying medicinal plants is warm-air drying. The HPLC results indicated that 50% (v/v) methanol demonstrated a good efficiency for recovering phenolic compounds, specifically chlorogenic acid (CGA), caffeic acid (CA), p-coumaric acid (PCA) and rutin (RUT).
