Etlingera Elatior

Background: Etlingera species is an enduring plant in the Zingiberaceae family, with more than 100 species local to many countries. It has been utilized commonly as a culinary spice or eaten crude for its therapeutic impacts. This research is intended to study the effects of E. elatior inflorescence, which is commonly known as bunga kantan in Peninsular Malaysia, upon the microbiota of healthy human gut. Material and methods: The closed bud E. elatior inflorescence was cleaned and dried in the hot air oven and grounded into fine powder. The extract from the E. elatior inflorescence was obtained using hot water extraction method. The effects of the inflorescence extract on L. rhamnosus and L. acidophilus were studied through micro-broth dilution process where different concentration of sample was incorporated into a broth medium followed by the application of a standardized volume of Lactobacillus sp. into the medium of the 96 well plate. Results: Growth was seen in both L. rhamnosus and L. acidophilus, indicating that E. elatior inflorescence acted like a prebiotic towards L. acidophilus and L. rhamnosus Conclusion: E. elatior inflorescence concentrate acts like a prebiotic towards L. acidophilus incomparable to L. rhamnosus

Defective Clearance

Hyperlipidemia often results from delayed or defective clearance, or overproduction of VLDL by the liver, which is subsequently transformed into LDL. The whole plant of Azadirachta indica was collected from local areas of Jaipur district areas of Rajasthan. The plant is authenticated by university of rajasthan by Drmanju Sharma dept of botany   Selected medicinal plant were cut into small pieces, cleaned and shade dried at room temperature then subjected to physical evaluation with different parameters. Macerated 5 g of air dried drug coarsely powdered with 100 ml of ethanol of the specified strength in a closed flask for twenty four hours, shaking frequently during six hours and allowed to stand for 18 h. About 2-3 g of powder is accurately weighed in a china dish and kept in hot air oven maintained at 110±1oC for four hours. After cooling in a desiccator, the loss in weight was recorded. This procedure was repeated till constant weight was obtained. For insoluble ash value Boiled the ash for 5-10 minutes with 25 ml of diluted hydrochloric acid, collected the insoluble matter in a Gooch crucible washed with hot water, ignited and weighed. Whole plant of Azadirachtaindicawas reduced to fine powder and was subjected to maceration in a 1 liter conical flask for 7 days at room temperature with alcohol (70%) water (30%). In the present study we aimed to screen various extracts of selected plants on Cholesterol induced hyperlipidemic rat model. Thus the results of the present investigation clearly indicated that the selected medicinal plants possess good antihyerlipidemic activity in atherogenic diet induced hyperlipidemic rats and led to the development of new Herbal formulation possessing antihyperlipidemic and antiatherosclerotic activities. This is the first study which investigates the hypolipidemic activity. Keywords: Azadirachta indica, antihyperlipidemic, antiatherosclerotic activities, Maceration.

The main objective of this research was to produce a simulated model that permitted the evaluation of operating costs of commercial greenhouse tomato growers with respect to heating methods (hot air, hot water, radiant and heat pumps) and the use of artificial lighting for 1991 and 1992. This research showed that the main factors that negatively influence profitability were energy consumption during cold periods and the price of tomatoes during the summer season. The conventional hot water system consumed less energy than the heat pump system and produced marketable fruit yields similar to those from the heat pump system. The hot water system was generally more profitable in regards to energy consumption and productivity. Moreover, investment costs were less; therefore, this system gives best overall financial savings. As for radiant and hot air systems, their overall financial status falls between that of the hot water system and the heat pump. The radiant system proved to be more energy efficient that the hot air system, but the latter produced a higher marketable fruit yield over the 2-year study.

A novel homogeneous polysaccharide named GEP-1 was isolated and purified from Gastrodia elata (G. elata) by hot-water extraction, ethanol precipitation, and membrane separator. GEP-1, which has a molecular weight of 20.1 kDa, contains a polysaccharide framework comprised of only glucose. Methylation and NMR analysis showed that GEP-1 contained 1,3,6-linked-α-Glcp, 1,4-linked-α-Glcp, 1,4-linked-β-Glcp and 1,4,6-linked-α-Glcp. Interestingly, GEP-1 contained citric acid and repeating p-hydroxybenzyl alcohol as one branch. Furthermore, a bioactivity test showed that GEP-1 could significantly promote the growth of Akkermansia muciniphila (A. muciniphila) and Lacticaseibacillus paracasei (L.paracasei) strains. These results implied that GEP-1 might be useful for human by modulating gut microbiota.

AbstractThe effectiveness of pressurized hot-water extraction conditions for obtaining galactoglucomannans (GGMs) from Pinus halepensis suitable for applications like coatings and films packaging was investigated. For this purpose, high molar masses with high yields are required, presenting a serious challenge for hot-water extraction processes. The extraction of GGMs was carried out in an accelerated solvent extractor (ASE) and the isolation was performed by precipitation in ethanol. Three temperatures in the range 160–180 °C and five extraction times 5–90 min were tested in order to optimize extraction parameters of GGMs, avoiding thermal and chemical degradation in hot-water. Total dissolved solids (TDS) were determined gravimetrically after freeze-drying and weight average molar masses (Mw) were determined by high-performance size exclusion chromatography (HPSEC). Total non-cellulosic carbohydrates were determined by gas chromatography (GC) after acid methanolysis. Free monomers were additionally analyzed by GC. Lignin in water extracts was measured by an ultraviolet (UV) method. Acetic acid was determined after alkaline hydrolysis of acetyl groups and analyzed by HPSEC. The main parameters influencing the extraction processes of the GGMs, namely, extraction time and temperature were studied. Optimal extraction parameters of GGMs were identified at 170 °C and 20 min extraction time, with average Mw of extracted fraction of 7 kDa leading to a GGM yield of approximately 56 ${\text{mgg}}_{\text{o}.\text{d}.\text{m}}^{-1}$, corresponding to 6% on dry wood basis.
