Nabam (I), methylmercury dicyandiamide (II), Dexon (III), nonenylsuccinic acid (IV) and its monomethyl ester (V), benomyl, Vitavax, Plantvax, and Uniroyal F849 and G696 were applied as drenches to the soil of potted tomato plants. Exudate collected for 6 h from the stumps of plants detopped 24 h after application of each chemical was markedly reduced in volume and total amino acid content by I–V but not the others. Relative levels of individual amino acids were little affected except that I induced changes in the relative amounts of several primary amino acids, and II increased alanine concentration in the exudates.

Basidiomycetous Mushroom

Objective: In this paper amino acid profile of Lentinus sajor-caju (Fr.) Fr., a basidiomycetous mushroom has been investigated.Methods: During the evaluation 15 amino acids (lysine, aspartic acid, serine, threonine, glutamic acid, cysteine, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine and histidine) were determined from the dried sample of Lentinus sajor-caju by following the standard technique of biochemistry using ion-exchange chromatography.Results: The total amino acid content has been evaluated at 18.82 g/100g. Amongst the evaluated amino acids, exogenous amino acid lysine (6.66 g/100g) is preponderantly present in comparison to all other amino acids. The essential amino acid (EAA) index (44.64%) and biological value (BV=36.93%) has also been determined for the examined sample.Conclusion: Lentinus sajor-caju (Fr.) Fr. is a potential source of quality protein with a substantial proportion of exogenous and endogenous amino acids.

AbstractTwenty-eight New Zealand White X Californian doe rabbits weighing 3791±141 g were surgically fitted with a glass T-cannula at ileum level. Animals were given ad libitum access to either a casein-based diet (C) or a protein-free diet (PF). The only difference in the ingredient composition of the diets was the substitution of 160g/kg of maize starch by casein in the C diet. Animals were randomly allotted to each experimental diet. Seven rabbits per diet were not allowed to practice caecotrophy. The C diet resulted in higher food dry matter (DM) intake (DMI) (111-5 v. 51-5 g/day), food nitrogen intake (3-12 v. 0-20 g/day), ileal flow of DM (56-0 v. 23-8 g/day) and ileal flow of nitrogen (0-72 v. 0-24 g/day) but lower soft faeces DMI (21-7 v. 41-4 g/day) than the PF diet. A linear relationship between ileal endogenous nitrogen flow and total DMI was found for animals given the C but not for the PF diet. The ingestion ofC diet led to a higher (proportionately 0-41, on average), endogenous ileal amino acid flow than PF diet for all amino acids except for glycine. The ileal flow of glycine was proportionately 0-25 higher in animals given the PF diet than in animals given the C diet. The C diet resulted in higher content of nitrogen, threonine and proline in soft faeces than the PF diet. In contrast, the ingestion of the PF diet led to a higher content of lysine and methionine in soft faeces than the C diet. Within the C diet, animals practising caecotrophy showed higher ileal flow of DM (73-4 v. 56-0 g/day) and phenylalanine (0-834 v. 0-677 g/kg DMI) than animals not practising it. Caecotrophy led to a higher endogenous proportion of some of the most important limiting essential amino acids in rabbits, such as arginine, lysine, phenylalanine and threonine. In rabbits, the use of PF diets has limited practical application in the estimation of nitrogen endogenous losses as the low food DMI and the high soft faecesDMI leads to abnormal food: soft faeces intake ratio. Moreover, due to the important effect of caecotrophy on the amino acid composition of endogenous losses, it is important to correct the total amino acid content of the ileal chyme by the undigested amino acid residue coming from the soft faeces intake. This correction could be made, without the methodological complexity implied, by fitting animals with a wooden collar and thereby avoiding caecotrophy as in the present trial.

<p style="text-align: justify;">Numerous studies have been carried out on the vine, must and wine, but few on sap. Main phenological stages i.e. bud burst, the flowering period, veraison and the ripening period have been well described. However, at the present time, no study is available identifying the main amino acids of the xylem sap, at the formentioned periods. Located within the « Graves de Pessac-Léognan » vineyard, the plot area studied has a clayey-chalky soil with a small amount of sand present. The cultivar Cabernet franc was grafted on the Fercal rootstock. Planted in June 1982, the vine was trained with Guyot pruning and no tillage. The density of the plantation was 5.550 vines per ha. Four rows of 21 vines were sampled.</p><p style="text-align: justify;">Analysis of xylem sap, by H.P.L.C., at the four stages, taken from several vintages, showed that the global content of amino acids varied year to year (LARCHEVÊQUE, 1998). The experiment reported on herein was carried out in order to determine both the main amino acids in the xylem sap and to identify a marker amongst them, having the same evolution as that of the global amino acid content from one phenological stage to the next. A pool of eight amino acids, all present in large quantities (about 80 p. cent of total amino acid content), was always noted : asparagine/glutamine, tyrosine, arginine, aspartic acid, glutamic acid, histidine and proline. Concentration levels of these components differed in sap, depending on the vintage, at the same phenological stage. At bud burst, as at the flowering period, the sap had a similar qualitative composition.</p><p style="text-align: justify;">It was noteworthy that aspartic acid evidenced the same evolution that of the total amino acid content (i.e. the same variation in percentage) from one phenological stage to the next. Aspartic acid should therefore be regarded as a « marker » of total amino acid content evolution during the vegetative cycle.</p>

Chemicals from fresh pomegranates were established. Total sugar of juice extracts are mainly fructose (ca. 7.27 g/100 ml) and glucose (ca. 8.11 g/100 ml). Pulp minerals, expressed as mg/100g are potassium (351.26), magnesium (10.02), calcium (9.26), sodium (7.25), iron (0.15), Zinc (0.10), copper (0.08) and manganese (0.04). Juice proteins are about 7.95 g/l and dry pulp proteins are 24% on a dry-weight basis DW (Kjeldhal assays). Seed proteins are ca. 16.87% DW. Globulins (62.4 mg/g DW) and albumins (54.12 mg/g DW) are the major storage protein fractions, followed by glutelins (33.2 mg/g DW) and prolamins (18.08 mg/g DW). Seed total amino acid content is 14.45 g/100 g DW. Seeds are rich in Glu, Arg, Asp, Leu and Gly amino acids. Essential amino acids average 33.54% of total amino acid. Essential amino acids are mostly all much higher than the requirement of FAO/WHO for adults (but none for preschool children). Most other amino acids have content slightly fewer. All of these findings implied that the content of sugar, mineral and protein maybe included in pomegranate as supplements for commonly diets.

Aim: The study of elicitors in grapevines has focused on inducing resistance to diseases and improving phenolic and volatile composition of grapes and wines. Due to the importance of nitrogen compounds in grape quality, the aim of this work was to study the effect of methyl jasmonate (MeJ) applied to two grapevine varieties on grape amino acid content during two consecutive seasons.Methods and results: Amino acids were analyzed by HPLC-DAD. The results showed that MeJ applications to Tempranillo grapevines decreased the concentration of certain amino acids during both seasons, but did not affect total amino acid content. Moreover, MeJ applications to Graciano grapevines increased the concentration of several amino acids during the second season.Conclusions: The effects of MeJ on grape amino acid concentration were conditioned by variety and vintage.Significance and impact of the study: The importance of this work is to provide more information with respect to the effects of elicitors on grape quality for good viticultural management.

Kawal is made by a natural or uncontrolled fermentation of Senna obtusifolia leaves. It is a food condiment, and appreciated because of its particular flavor. It is also used as a meat or fish substitute. Kawal is an important source of protein in the diet of low-income families. The present work was done to determine the total amino acid content in raw and fermented Senna obtusifolia leaves. The high performance liquid chromatography (HPLC) with The Pico-Tag method was used for the analysis and determination of amino acid profiles. The results obtained showed that the kawal protein is rich in essential amino acids and semi-essential for humans, with different concentrations. Leucine gave a maximum value of 208.56 mg/100 g (DM) and 538,29 mg/100 g (DM); valine showed the value of 173,46 mg/100 g (DM) and 476.25 mg/100 g (DM), for lysine this value is 205.58 mg/100 g (DM) and 456.13 mg/100 g (DM). In the background, we have histidine, threonine, tyrosine, isoleucine and phenylalanine, whose best concentrations are between 157.36 mg/100 g and 397.93 mg/100 g (DM) in fermented leaves. For semi-essential amino acids, the fermented leaves have concentrations of between 121.96 mg/100 g and 1260.92 mg/100 g (DM).

The results of the research on the assessment of the biological value of wheat after storage by the composition and ratio of amino acids are presented. It is shown that after 6.5 years of storage in elevator silos, the protein content in wheat met the requirements of the standard for class 3 wheat. The sum of all amino acids was from 11.5 to 13.1 g / 100 g, including essential amino acids — 4.0-4.5g/100g and non-essential — 7.8-8.7 g / 100 g. The proportion of essential amino acids was 33.7-35.3% of the total amino acid content. The calculation of the amino acid score demonstrated that the main amino acid limiting the nutritional value of wheat after storage is lysine with an amino acid score of 45-53%. The essential amino acids threonine, valine, isoleucine, and leucine are also classified as deficient, but with a higher value of the amino acid score, close to the complete protein.
