The hypolipidemic effect of red gram prebiotics of raffinose family oligosaccharides was studied in Wistar National Institute of Nutrition male rat strain. The study consisted of 36 rats randomly divided into three groups of 12 rats each. For 16 weeks, Group I was fed with the control diet; Group II was fed with a diet containing 3% standard raffinose as the reference group; Group III received the diet containing 3% red gram prebiotics. The results showed that the gain in body weight was low in the red gram prebiotics-supplemented group followed by the control group; highest increase of body weight was seen in the raffinose standard-fed group. Serum glucose levels of the red gram prebiotic-fed group decreased 14.92% compared to the control group and increased 2.07% compared to the reference group. The decrease in serum triglycerides (TG) levels of the red gram prebiotic-fed groups was 32.76% compared to the control group and 33.64% compared to the reference group. Decrease in the serum TC of the red gram-fed animals was 18.51% and 4.63% compared to the control group and the reference group, respectively. Increase in the level of serum high-density lipoprotein cholesterol (HDL-C) in the red gram-fed animals was 18.51% compared to the control group and 4.63% compared to the reference group. The present study can be a proof for the use of prebiotics as a preventive measure for overweight and obesity in humans, and legume prebiotics can be explored as a novel prebiotic product in the consumer market.

Context Ocimum sanctum Linn (Labiatae) (OS), Zingiber officinale Rose (Zingiberaceae) (ZO), and Piper nigrum Linn (Piperaceae) (PN) are used in traditional medicine as immunomodulator, anti-inflammatory, and bioavailability enhancer agents. Objective Active phytoconstituents of OS, ZO, PN hydro-alcoholic extracts and their effects on gut microbiota, basal inflammation and lipid profile were investigated in rats. Materials and methods Active phytoconstituents of extracts were analysed using HPLC and GC-MS. SD rats were supplemented with individual/combined extracts (OS-850; ZO-500; PN-100 mg/kg Bw) and Fructooligosaccharide (standard prebiotic-5g/kg-Bw), orally for 30 days. Haematology, lipid profile, LPS, CRP, IL-6, insulin and histology of vital organs were analysed. Caecal bacterial levels were assessed by RT-PCR. Results High content of phenolic compounds luteolin-7- O -glucoside (430 ± 2.3 mg/100g), gallic acid (84.13 ± 1.2 mg/100 g) and flavones (88.18 ± 1.8 mg/100 g) were found in OS, ZO, and PN, respectively. Combined extract was rich in luteolin-7- O -glucoside (266.0 ± 1.80 mg/100 g). Essential oils including methyleugenol (13.96%), 6-shogaol (11.00%), piperine (18.26%), and cyclopentasiloxane (10.06%) were higher in OS, ZO, PN and combined extract. Higher levels of caecal Lactobacillus (1.7–3.4-fold), Bifidobacterium (5.89-28.4-fold), and lower levels of Firmicutes (0.04–0.91-fold), Bacteroides (0.69–0.88-fold) were noted among extracts and FOS supplemented rats. Significant ( p < 0.05) decrease in plasma lipid profile and LPS was noted in all supplemented rats. Discussion and conclusions The current study could be first of its kind in exploring prebiotic potential of OS, ZO, PN and their effect on native gut bacterial population.

Synbiotic supplementation to pregnant dams affected the offspring's cellular and mucosal immunity favorably. However, IgG response to Hepatitis-B vaccine was influenced positively only when the supplementation was extended to the offsprings in the post weaning period. © 2016 Society of Chemical Industry.
