The concept of “medicinal fruits and vegetables” has attracted much research attention recently. Medicinal fruits and vegetables are rich in nutrients and high in edible value, and are also necessary for people’s daily diet. In order to better exert the effect of medicinal fruits and vegetables and prolong their shelf life, this paper reviews the effects of common thermal processing methods (boiling, steaming, microwaving, hot air drying, and pasteurization) on the bioactive compounds and pharmacological activities of medicinal fruits and vegetables. It is found that different heat treatment methods have their own advantages and disadvantages, and microwave drying has greater advantages in comparison. Through the summary of the thermal processing methods of medicinal fruits and vegetables, it is expected to provide a theoretical reference for its rational utilization in the field of fruits and vegetables and the improvement of thermal processing methods.

內(nèi)容: A high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was built to determine icarside, hyperoside and psoralen in food. The samples were extracted with 70% methanol, the solid and semi-solid hotpot seasoning samples were purified by solid phase extraction column, and then determined by HPLC-MS/MS. Acetonitrile and 0.1% formic acid solution were used as the mobile phase, and the gradient elution was adopted for analysis. The analytes had good linearity in the range of 0.05?100 ng/mL, and the correlation coeffificients (R2) were greater than 0.999. In this method, the limits of quantitation (LOQ) of psoralen, icariside and hyperoside in liquid samples were 1.25, 25.0 and 12.5 μg/L, respectively; while the LOQs of psoralen, icariside and hyperoside in solid samples and hotpot seasoning samples were 1.25, 25.0 and 12.5 μg/kg, respectively. The liquid beverage, solid beverage, health food (in the form of oral liquid, capsule, tablet), integrated alcoholic beverage and solid hotpot seasoning were selected as representative samples and used for method validation. The average spiked recoveries at 3 levels (LOQ, 2 LOQ, 10 LOQ) were in the range of 83.7%?115.0%, and the relative standard deviations were in range of 0.5%?9.4% (n = 6). The method is rapid, accurate and sensitive, which is suitable for the simultaneous determination of icariside, hyperoside and psoralen in different food matrices.

內(nèi)容: Lagerstroemia indica L. has a high medicinal value, its bark, leaves and flowers can be used as medicine. Its flowers are reddish, purple, or white, thereinto, the white one is called L. indica Linn. f. alba (Nichols.) Rehd., which is a forma of L. indica. In this paper, the hypoglycemic effects of different extracts from flowers of L. indica (LIF) and L. indica L. f. alba (Nichols.) Rehd. (LIAF) were investigated by α-glucosidase inhibitory method in vitro and alloxan-induced diabetic mice model in vivo, respectively. The results in vitro showed that ethyl acetate extracts (EA) of LIF and LIAF (IC50 = 4.45 and 4.09 μg/mL, resepectively) had the highest inhibitory activity of α-glucosidase, and followed by n-butyl alcohol extracts (BU) (IC50 = 17.01 and 14.58 μg/mL, respectively), and the last was petroleum ether extracts (PE) (IC50 = 103.29 and 112.47 μg/mL, respectively), the activities of all extracts were higher than that of the positive control (acarbose, IC50 = 1 278.83 μg/mL). The results in vivo showed that compared with the model control group, each dose group of LIF could significantly (P < 0.05, P < 0.01 or P < 0.001) decrease fasting blood glucose, total cholesterol (TC) level and malondialdehyde (MDA) content in diabetic mice and increase superoxide dismutase (SOD) level (P < 0.05) in serum. Partial dose groups of LIF could significantly (P < 0.05) decrease postprandial blood glucose, triglyceride (TG) and increase liver glycogen content. Each dose group of LIAF could significantly (P < 0.05, P < 0.01 or P < 0.001) decrease fasting blood glucose, TC level and increase SOD level in serum. Partial dose groups of LIAF could significantly (P < 0.05) decrease TG, MDA level and increase liver glycogen content. These results indicate that LIF and LIAF had effective prevention and treatment effects on the development for diabetes.

內(nèi)容: The well-known relation between food and bioactives explores the great prospective of innovative and novel food to maintain or improve health, increasing the demand investigating advance products with medicinal effect. Withania somnifera also known as ‘Ashwagandha’ in India, is one of the most utilized plants in different ancient medicine systems. The present work is an effort to develop a knowledge-based concept and a quality control approach for the development of functional foods. The study took into account the standardization criteria and examined how different geographies or different field sites (of India) would influence the phytoconstituents and their distribution in the different samples of W. somnifera. Phytoconstituents level were strongly influenced by soil quality, cultivar, and growing season. An increase in phenolic content, flavonoid content, antioxidants and the quality yield, were all correlated with increased phytoconstituent concentrations. The highest hydro-methanolic extract yield (by reflux (Soxhlet), sonication (20 min) and maceration (16 h) was from the sample collected from Rajasthan (18.61%, m/m) followed by West Bengal (11.21%) and Madhya Pradesh (12.67%) respectively. The methanolic extract of Rajasthan sample (produced by the reflux (Soxhlet) extraction method) had the highest concentrations of flavonoids (65.32 mg quercetin equivalent (QE)/g) and the total phenols (60.35 mg gallic acid equivalent (GAE)/g), while Madhya Pradesh sample (distilled water reflux (Soxhlet)) extract had the highest antioxidant content (74.13 %). High performance thin layer chromatography (HPTLC) method was also utilized for identification of withanolides A. Chromatographic separations were carried out using V(ethyl acetate):V(toluene): V(acetic acid) = 9.1:1:0.6 as the mobile phase. The gas chromatograph-mass spectrometer (GC-MS) study of hydro-methanolic Soxhlet extract of W. somnifera from 3 different regions of India was done and the total phytochemical substances identified were 132 in sample from Rajasthan, 107 in sample from West Bengal, and 164 in sample from Madhya Pradesh respectively. To conclude, the present study demonstrates how, within a framework of integrated agricultural practices, yield and phytochemicals merge into a new paradigm of functional foods.
