Comparative functional potential of some plant materials in India
Soluble dietary fibers are known to play an important role in maintaining health. These may have prebiotic activity and additionally their basic physico-chemical properties may contribute to their multifunctional health potential. Present study was planned with 30 plant materials grouped as fruits, vegetables, and other tuber crops using gum acacia as standard, being a known dietary fiber having prebiotic potential. The materials were studied for water holding capacity, cholesterol and bile salt binding activity, α-amylase inhibition and trypsin inhibition activity. Fifteen plant materials showed cholesterol binding capacity significantly higher than gum acacia by 0.7 to 86 %.Nineteen plant materials were found to have bile salt binding capacity (27-99 %) higher than gum acacia (24 %). Water holding capacity was observed in the range of 2.71 to 35.4 g/ g dry material for all the materials, while gum acacia had the least value of 0.82 g/ g dry weight. Sixteen materials showed α-amylase inhibition in the range of 9.99-95.0 % as compared to 9.65 % of gum acacia. Trypsin inhibition activity showed in the range of 49-98 %. This is the first report of multifunctional activities of plant materials with prebiotic potential. The results may help to develop prebiotic formulations having multifunctional potential for treatment of gastrointestinal disorders

Antioxidant and trace element potential of Chyavanpraash and some Ayurvedic preparations
215-223Importance of antioxidants
such as vitamin C and zinc in treatment of diabetes mellitus
and hypertension is being
recognised. There is a growing interest to find naturally occurring
antioxidants rather than synthetic ones for their use in medicinal material.
Therefore a study was undertaken a) to assess antioxidant and trace metal
potential of five brands of Chyavanpraash and eight marketed Ayurvedic
preparations (AP) at their prescribed dose level along with their major nine
ingredients; b) to measure bioavailable amounts of trace metals; and c) to
examine toxicity of lead in these AP. Trivang, Abhrak and Loha bhasma had
high levels of copper, cobalt and nickel. Manganese contents were high in
Trivang and Abhrak but zero in Lohabhasma. Even though amalaki is one of the
main ingredients of Chyavanpraash and Raktavardhak, their vitamin
C content was quite low. Tannic acid was marginal in these two preparations.
Three types of amalaki showed variable contents of iron, zinc, copper, lead,
manganese and ascorbic acid. Tannic acid was highest in small
amalaki. Sun drying reduced vitamin C content by seventy five percent of the
fresh amalaki. Lohabhasma showed highest bioavailable iron followed by
Lohachurna. The bioavailable iron was negligible in Chyavanpraash and
Raktavardhaka as compared to Lohabhasma and Abhrak bhasma. Bioavailable
zinc content was high in Trivang bhasma and is a promising zinc
supplement. Mineral iron treated with Gomutra decreased % iron
bioavailability by one third but % zinc bioavailabiliy
increased twofold. Lead content was highest in Trivang bhasma. The
content of lead in daily dose of Chyavanpraash and Raktavardhak was high, but
within the prescribed safe limits for lead. Further the bioavailable
amount of lead for all these preparations was also very low
