Biochemical, Nutritional and End Use Perspectives of Wheat Grass as Potential Dietary Supplement

Wheat grass being substantial cereal grass crop in the world; copious source of nutrients with noteworthy nutritional and therapeutic value. The research, wheat grass was grown in indoor trays and then used as powder and in drink. The objective were to use the wheat grass to formulate a suitable processing procedure for wheat grass powder (WGP) enriched food products. Both raw WGP and cookies were analyzed for total dietary fiber (TDF), soluble dietary fiber (SDF), insoluble dietary fiber (IDF), total phenolic content (TPC) and antioxidant activity. Drink was analyzed for pH, viscosity and total soluble solids (TSS). WGP addition showed a significant effect on mixographic (peak height and peak time) and farinographic studies; water absorption, arrival time, dough development time (DDT) and mixing tolerance index (MTI). The cookies prepared using different levels were generally accepted by sensory panelists of the department but 3% substitution level of WGP have high acceptability. Moreover, on the basis of physicochemical and sensory attributes, 10% supplementation level of wheat grass in drink was best making it a nutrient enriched food source.

Role of Triticum aestivum aqueous extract in glucocorticoid induced osteoporosis in rats.

Administration of aqueous extract of T. aestivum (200 and 400 mg/kg/day, po, for 30 days) and risedronate (20 mg/kg, sc, five times a week for 30 days) following methyl prednisolone sodium succinate (10 mg/kg, sc, thrice a week for 4 weeks) induced osteoporosis in Wistar rats showed an increase in the serum levels of bone mineral content markers, decrease in the serum and urinary levels of bone resorption markers. An incline in strength of femur and tibia was seen particularly with 400 mg/kg of T. aestivum. Maintenance of calcium homeostasis, formation of collagen and scavenging of free radicals can plausibly be the mode of action of aqueous extract of T. aestivum thereby combating osteoporosis induced by glucocorticoids.

In vitro Studies of Iron Chelation Activity of Purified Active Ingredients Extracted from Triticum aestivum Linn. (Wheat Grass).

Objective: Seven to eight days germinated plants of Triticum aestivum (wheat grass) are a rich source of vitamin A, C, calcium, magnesium, phosphorus, potassium, sodium, sulphur, cobalt, zinc and protein. Traditionally the aqueous extract of T. aestivum was reported to be used as a health tonic in folk and ayurvedic medicine. We previously reported that aqueous extract of T. aestivum was found to reduce the blood transfusion requirement in iron overloaded Thalassemia and Myelodysplastic syndrome patients. Our objective was to extract and purify active ingredients from wheat grass and study their mode of action in stabilizing hemoglobin level in those patients. Design and Method: Active ingredients of wheat grass were extracted and purified by cation exchange column chromatography followed by High Performance Liquid Chromatography. In vitro experiments with phenylhydrazine treated red blood cell hemolysate were carried out before and after treatment of purified fraction of T. aestivum to study iron chelating activity. Result: Purified fraction of T. aestivum treated red blood cell showed significant inhibition of free reactive iron production and formation of thio-barbituric acid reactive substances when compared to desferrioxamine treated hemolysate. Conclusion: Iron chelating activity of purified fraction of T. aestivum, an inexpensive, easily available source, is very promising for further clinical trial and development of oral iron chelator drug for Thalassemia, Myelodysplastic syndrome and other iron overloaded diseases.

Effect of wheat grass tablets on the frequency of blood transfusions in thalassemia major.

Forty patients of Thalassemia Major children were treated with wheat grass tablets (WGT). The mean hemoglobin in the pre WGT was 8.54 +/- 0.33 g% whereas in WGT period was 9.13 +/- 0.14 g% (p < 0.001). The mean blood transfused as packed cells in pre WGT period was 326.82 +/- 74.10ml/kg/year whereas during WGT period it was 256.39 +/- 45.47 ml/kg/ year. The percentage difference in the amount of packed cells transfused in pre WGT and WGT period was 18.02 +/- 22.96 (p < 0.001). The decrease in the blood transfusion requirements was by 25% or more in 20 (60.6%) cases. The mean interval between the consecutive blood transfusions in Pre WGT period was 18.78 ± 4.48 days whereas in WGT period was 24.16 ± 4.78 days (p < 0.001). Wheat grass has the potential to increase the Hb levels, increase the interval between blood transfusions and decrease the amount of total blood transfused in Thalassemia Major patients.
