Nutritional Constituents

Aegle marmelos Correa commonly known as “Bael,” has been recognized as a component of traditional medication for the treatment of various human ailments. The present study was focused on phytochemical screening, nutritional constituent of A. marmelos at different development stages. Highest amount of alkaloid was in premature bael (8.09±0.09 mg/g), phenols in premature bael (9.65±0.06 mg/g) pulp and saponins in mature bael(5.57±0.08) pulp. Highest amount of thiamin (B1) (1.83±0.03 mg/100 g) and ascorbic acid (48.62±0.04 mg/100 g) in premature bael pulp. Sugar content significantly highest in matured bael(6.94±0.04 mg/100 g) pulp. Most abundant mineral potassium content was maximum in (139.61±0.04 mg/100 g) premature bael fruit pulp. The nutritional constituents and phytochemicals change depending on maturation stage. Nutritional constituent changes on the effects of development of bael (Aegle marmelos) fruit. It has been found in the present study that there were a numbers of phytochemical changes occurred during different fruit development stages.

Abstract Two years experiment was carried out to compare the nutritional composition in bulbs of ten onion cultivars grown in the field conditions. Pyruvic acid, ascorbic acid and soluble sugars were determined in the edible part of onion bulbs. In most cultivars the content of pyruvate as the pungency index was ranged between 3-7 μmol g-1 fresh weight (medium pungency), however, three of them exceeded 7 μmol g-1 fresh weight (high pungency). A higher level of pyruvate corresponded in most cases with higher sugar content but was not correlated with that of ascorbic acid.

Development Stages

Dynamic changes in flavonoid, total phenol, and antioxidant potential in different Prunus humilis accessions during fruit development stages were studied in order to provide a reference for the optimum harvest time for flavonoid extraction. ‘Nongda 4’, ‘Nongda 5’, ‘DS-1’ and ‘02–16’ were selected as plant materials to determine the content of flavonoid, total phenol and antioxidant indices during six fruit development stages. Changes in total flavonoid content (TFC) and total phenol content (TPC) in different accessions of P. humilis were slightly different depending on the development stage of P. humilis fruit. TFC and TPC in ‘Nongda 5’ fruit showed a trend of continuous decline. There was a small increase in TFC and TPC from the young fruit stage to the stone hardening stage, followed by a decreasing trend, and then to the lowest level at the ripening stage of ‘Nongda 4’, ‘DS-1’, and ‘02–16’ fruits. The trend of antioxidant capacity (ABTS, FRAP, DPPH) with the TFC and TPC of P. humilis fruit was basically the same, and the correlation analysis results showed that the TFC of P. humilis fruit was positively correlated with the antioxidant indices (P<0.01). Catechin (CC), rutin (RT), and quercetin-7-O-β-D-glucopyranoside (Q7G) were detected in all the fruit development stages of the four P. humilis fruits. Among them, catechin was the most abundant component, accounting for approximately 10%. Myricetin (MC) and quercetin (QC) were generally detected only in the early fruit development stage, but not in the later fruit development stage. Correlation analysis showed that the flavonoid components with TFC, TPC, and antioxidant indices differed between the different accessions. RT, CC, and liquiritigenin (LR) had a stronger correlation with TFC and antioxidant indices. Cyanidin-3-O-glucoside (C3G) was not detected until the coloring stage in two red P. humilis accessions (‘Nongda 4’ and ‘DS-1’), and so it is better to choose a red P. humilis fruit to extract C3G at the ripening stage. Selecting an early stage of fruit development, especially the stone hardening stage, was important for extracting flavonoids, total phenols and other components. We believe that our results will provide basic information and reference for evaluation of fruit nutrition and health benefits, breeding of functional new varieties, and efficient utilization of P. humilis fruit.

ABSTRACT: This work describes ethylene and 1-methylcyclopropene (1-MCP) action on post-harvest shelf life of four development stages of nasturtium flowers. To reach this goal, we carried out three experiments. In the first and second experiments, we studied five ethylene (0; 0.1; 1; 10; 100 and 1000 μL/L) and three 1-MCP concentrations (0.25; 0.5 and 0.75 μL/L), respectively. In the third experiment, 1-MCP was followed by combined with ethylene (only 1-MCP; only ethylene; and 24 hours of exposure to 0.75 μL/L 1-MCP followed by 24 hours of exposure to 100 μL/L ethylene). All experiments had two control treatments, one keeping non-exposed flowers inside and another outside exposure chambers. Experiments were set in factorial design, in complete blocks at random, with four 10-flower replications each. Flower senescence was determined by a pre-established visual scale and by observing floral bud development. Ethylene dose above 10 μL/L induced flower wilting and premature senescence from the second floral development stage. Furthermore, higher concentrations of exogenous ethylene promoted irregular flower opening and/or morphological abnormalities in opened flowers. 1-MCP effectively extended post-harvest longevity of nasturtium flowers, independent of the concentration and even in the presence of exogenous ethylene.

Berry Size

To better understand the sensitivity of berry size and grapevine photosynthesis to water stress, and determine the soil water potential (ψ) threshold for scheduling irrigation during the maturation stage, we simultaneously measured berry size with photographs, leaf net photosynthesis with a portable meter, and ψ with tensiometers during the drying cycles for grapevines (Vitis vinifera L.). Our results showed that in berry development stage III (maturation), photosynthesis was more sensitive to water stress than berry size. When ψ decreased beyond −13.2 ± 0.82 kPa, photosynthesis, stomatal conductance, transpiration, and extrinsic (AN/E) and intrinsic (AN/gs) water use efficiency (WUE) decreased rapidly and did not recover thereafter. In contrast, the berry size remained close to unaffected by the decreasing ψ until it reached a value of −16.2 ± 0.77 kPa and, thereafter, the berry shrank significantly. In conclusion, we suggest that during the maturation stage of grapevines, for the potted mixture used in our experiments, irrigation should be triggered when the ψ reaches a value of −13.2 ± 0.82 kPa. Further, ψ should be kept lower than −6.9 ± 0.15 kPa after irrigation, because the highest values of intrinsic WUE (AN/gs) occurred when ψ decreased from −6.9 ± 0.15 to −14.6 ± 0.7 kPa. In arid areas, the threshold ψ should be considered as −16.2 ± 0.77 kPa during maturation to achieve high-efficiency use of water resources and sustainable production of grapevines.

The objective of this study was to evaluate the phytochemical and pharmacological screening of fruit extracts of Aegle marmelos using various in vitro methods. The antioxidant activity of the extracts was evaluated by using DPPH free radical scavenging and reducing power method, while well diffusion method was used for antimicrobial activity. Phytochemical screening indicated the presence of flavonoids, and phenolics were abundantly present in methanolic and aqueous extracts of A. marmelos. Methanolic extract showed significant antioxidant potential, which was however inferior to that of ascorbic acid. The methanolic extract showed maximum zone of inhibition against the S. aureus (18 mm) and it was higher than that of the standard tetracycline. The HPLC data predict that the presence of scopoletin, marmelosin and umbelliferone, which may contribute to their pharmacological action.

Extracts of the leaves, stem, roots, and seeds of <em>Mitracarpus scaber</em> plants have been thoroughly investigated in an attempt to determine their phytochemical and antioxidant activities.<em> </em>Phytochemical screening carried out by thin-layer chromatography (TLC) revealed the presence of several secondary metabolites in all the selective extracts of the plant. The levels of phenolic compounds showed that the leaves of <em>M. Scaber</em> are the richest in polyphenols with an average value of 488.291 ± 1.205 μg GAE/g (microgram of gallic acid equivalent per gram of the dry matter of the powdered plant). The total flavonoid assay revealed a high content in the leaves (1.624 ± 0.032 %). Also, studies of the antioxidant activities by DPPH<sup>● </sup>(2,2-diphenyl-1'-picrylhydrazyl) method showed a significant effect compared to vitamin C (96.62 %). The percentages of inhibition are respectively 89.82 % and 82.3 % for ethyl acetate extracts of the leaves and seeds. Furthermore, the inhibitory percentages of n-butanol in the leaves and seeds are 90.57 % and 83.67 %, respectively. Calculated IC<sub>50</sub> showed that the n-butanol fraction of the seeds exhibited the highest activity with an IC<sub>50</sub> of 0.293 mg/mL less than ascorbic acid with an IC<sub>50</sub> of 0.387 mg/mL.

<p>Este trabalho teve como objetivo avaliar os parâmetros físico-químicos de polpas de fruta produzidas e comercializadas na cidade de Petrolina-PE, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define as características físicas e químicas estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram avaliadas duas marcas (1 e 2) de polpas de abacaxi, cacau, caju, graviola, maracujá e umbu, analisadas quanto aos parâmetros de pH, sólidos solúveis totais (SST), acidez total titulável (ATT), ácido ascórbico, relação SST/ATT e sólidos totais. Os resultados permitem inferir que a marca 2 apresentou qualidade superior na maioria dos parâmetros avaliados quando comparado com a marca 1. Entretanto para alguns sabores de polpa as duas marcas não atenderam os valores padrões. Entre as polpas o único sabor que apresentou os padrões exigidos foi a polpa de caju em ambas as marcas, e a que apresentou resultado de pior qualidade diante dos padrões foi a polpa de maracujá principalmente da marca 1. Dessa forma constata-se que há grandes variações entre as marcas, e entre alguns parâmetros, o que compromete a qualidade das polpas, prejudicando assim o consumidor.</p><p align="center"><strong><em>Physicochemical parameters of fruit pulps produced in Petrolina – PE</em></strong></p><p><strong>Abstract</strong><strong>: </strong>This study aimed to evaluate the physicochemical parameters of fruit pulps produced and marketed in the city of Petrolina-PE, with reference to the Instruction Nº 1 of 7 January 2000 of the Ministry of Agriculture, which defines the physical and chemical characteristics setting minimum and maximum limits specific to each fruit pulp. We evaluated two brands (1 and 2) of pineapple, cocoa, cashew, soursop, passion and umbu fruit pulp, analyzed for pH, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid, TSS / TTA and total solids parameters. Results show that the brand 2 showed superior in most evaluated parameters when compared to the brand 1. However, for some pulp flavors of both brands did not reached the standards values. Among the pulps, the only flavor that presented the required standards was the cashew pulp in both brands, and presented the results of lower quality on the standards was the passion fruit pulp mainly brand 1. Thus, it appears that there are great variations between brands and between some parameters, which compromises the quality of the pulp, thus impairing the consumer.</p>
