The present study aims to develop an herbal tea formulation from leaves of Moringa oleifera incorporating with rhizomes of Alpinia galanga and the inflorescence of Elsholtzia communis with an insight to improve its sensory attributes and also enhancing the nutritional value. The ingredients were processed and three herbal teas HT1, HT2, HT3 were formulated by mixing them at different levels of incorporation. Acceptability trials for color, aroma, taste and overall aceptability revealed that HT2 was the most liked infusion with highest scores for color (7.8), taste (8.04) and overall acceptability (7.96). The total antioxidant capacity of HT2 was determined by the DPPH scavenging activity test by the method of Blois. The methanolic extracts of the herbal tea sample showed 76.12% radical scavenging activity whereas the sample extracted with DMSO showed a lower antioxidants capacity of 62.45%. The shelf life of the herbal tea was studied by storing in different packaging materials. HDPE Zip loc bags, tea bags (packed in paper cartons) and HDPE containers stored the product without spoilage over a period of six months. The developed herbal tea has a good market potential with significant health benefits.

Olax scandens Roxb. (family Olacaceae) Available in throughout tropical India. The current study, aerial parts of different extracts of Olax scandens by different in-vitro methods. The antioxidant activity was evaluated by Hydroxyl radical scavenging activity(OH radical), Nitric oxide radical scavenging activity(NO radical), and total antioxidant activity (Phosphomolybdic acid method) with reference standard Ascorbic acid. An IC50 value was originated that methanolic extracts of Olax scandensis more efficient in Hydroxyl radical scavenging activity, Nitric oxide radical scavenging, total antioxidant activity than that of EA and petroleum ether extract. The methanolic  extracts  of Olax scandens & ascorbate exhibited antioxidant potential possessing IC50 253µg/ml & 135µg/ml (NO radical ), 205µg/ml & 57µg/ml (Phosphomolybdic acid method), 265µg/ml & 65µg/ml (OH radical) respectively. But when compared to all the three extracts with ascorbate (standard), the methanolic extract of the Olax scandens showed a better result. Moreover, the results were observed in a concentration-dependent manner. Invitro antioxidant studies obviously showed that methanolic extracts of Olax scandens have better antioxidant activity. These results indicate that aerial parts of methanolic concentrates Olax scandals could serve as a natural antioxidant, which may be useful to prevent free radical-induced diseases.

<p>Wheatgrass at young green stage is a powerhouse of nutrients and phytochemicals. Its various formulations are available in the form of extracts or powders used as health supplements. However, there is a huge potential of utilization for wheatgrass in the development of health foods for general good health as well as cure of disorders like metabolic syndrome, cancer, thalassemia, aneamia etc. With an aim to develop wheatgrass enriched health foods, the wheatgrass powder could be incorporated up to 10% in chapati and biscuits and up to 5% in bread without compromising the overall acceptability of the products. The free radical scavenging activity of chapati, biscuits and bread were increased significantly (p&lt;0.05) at the optimized levels of enrichment of wheatgrass powder in these products. Food sprinkler enriched with 50% wheatgrass powder enhanced the free radical scavenging activity of the spices by 26% without affecting the sensory attributes of the product. Hence, these wheatgrass powder enriched health foods may possess health promoting properties owing to their high antioxidant activity.</p>

The juice sacs of pummelo fruit is susceptible to softening during storage at 25 °C, which causes quality deterioration and flavor loss during postharvest pummelo storage. This study investigated the changes in metabolisms of antioxidant and cell wall in juice sacs of three pummelo cultivars—Hongroumiyou (HR), Bairoumiyou (BR) and Huangroumiyou (HuR)—during postharvest storage. The results revealed that, with the extension of storage, the juice sacs of three pummelo cultivars exhibited a decrease in total antioxidant capacity (TAC), DPPH and ABTS radical scavenging activity; a decline in total phenols (TP) content and an increase firstly then a decrease in total ascorbic acid (TAA) content; and a decrease in lipoxygenase (LOX) activity and a rise initially, but a decline in activities of ascorbate peroxidase (APX) and glutathione peroxidase (GPX). Additionally, increased water-soluble pectin (WSP), but declined propectin, ionic-soluble pectin (ISP) and chelator-soluble pectin (CSP); as well as an increase from 0 d to 60 d then followed by a decline in activities of pectinesterase (PE), polygalacturonase (PG) and pectate lyase (PL) were observed. These results suggested that the metabolisms of antioxidant and cell wall could result in softening and senescence of pummelo fruit.

Southern Thailand

Turmeric (Curcuma longa L.), a member of Zingiberacaeae, is used for Thai traditional medicine, flavoring, preservative, and coloring agent. In Southern Thailand, turmeric is a famous ingredient for food recipes. Not only is the ripened rhizome used for cuisine, but also the young rhizomes. Previous studies have indicated that a variety of turmeric products from the ripened rhizome are valuable source of antioxidant compounds. However, there are ambiguous data regarding the level of antioxidant activity of the young rhizome. The aim of this study was to investigate the level of total phenolic content (TPC) and antioxidant activity of the young rhizomes by comparing to the ripened rhizome. TPC and antioxidant activity of aqueous and 80% methanolic extracts from the young turmeric grown in Southern Thailand were estimated using the Folin-Ciocalteu method and DPPH free radical scavenging activity (DPPH-RSA) assay, respectively. Results showed that the concentration of TPC determined in methanolic extract (19.80±0.25 mg GAE/ g extract) from the young rhizome was significantly higher than the corresponding aqueous extract (18.38±0.41 mg GAE/ g extract). The aqueous and methanolic extracts exhibited significant inhibition in DPPH-RSA with the half-maximal inhibitory concentration (IC50) value of 5.88±0.70 mg/mL and 3.00±0.31 mg/mL, respectively. However, in comparison with the ripened rhizome, TPC and DPPH-RSA of the young rhizome were lower. These results indicate that the young rhizome grown in Southern Thailand could be a source of antioxidant compounds, but the ripened rhizome provides better antioxidant properties than the young rhizome.

The methanol extract of the leaves of Buddleja asiatica Lour. (Loganiaceae) showed antioxidant activity toward the well known in vitro antioxidant tests such as total antioxidant capacity by the phosphomolybdenum method, free radical scavenging activity by the 1,1- diphenyl-2-picrylhydrazyl scavenging assay (DPPH assay) and hydrogen peroxide scavenging methods. Due to the high scavenging activity of the n-butanol successive fraction toward DPPH and H2O2 (SC50 = 11.99 and 18.54 μg/ml, respectively), this extract was subjected to chromatographic separation and isolation. Four non-phenolic compounds were isolated and identified on the basis of spectroscopic and chemical analyses: 1-O-ß-D-glucopyranosyl- 2-methoxy-3-(2-hydroxy-triaconta-3,12-dienoate)-glycerol (1), 3-O-[α-l-rhamnopyranosyl- (1→4)-ß-d-glucopyranosyl-(1→3)]-[ß-d-glucopyranosyl-(1→2)]-ß-d-fucopyranosyl-olean- 11,13(18)-diene-3ß,23,28-triol (2), 3-O-[α-l-rhamnopyranosyl-(1→4)-ß-d-glucopyranosyl- (1→4)-ß-d-glucopyranosyl-(1→3)]-ß-d-fucopyranosyl-olean-11,13(18)-diene-3ß,23,28-triol (3), and 3-O-[α-l-rhamnopyranosyl-(1→4)-ß-d-glucopyranosyl-(1→3)]-[ß-d-xylopyranosyl- (1→2)]-ß-d-glucuronopyranosyl-acid-olean-11,13(18)-diene-3ß,23,28-triol (4). The four compounds were evaluated as antioxidant agents using the three antioxidant bioassay tests.
