Elaeagnaceae

Urolithiasis is a common worldwide problem with high recurrence. This review covers forty four (44) families starting from alphabet A to L and includes Bignoniaceae (05) Juglandaceae (01) plant used globally in different countries. The plants of three families Asteraceae, Fabaceae and Lamiaceae are revisited to provide updated information. This review will not only be useful for the general public but also attract the scientific world for antiurolithiatic drug discovery.

Diversity needs to be “conserved through use.” Owing to the global need, the present study includes two underutilized berries, Carissa carandus and Eleagnus conferta, to explore their potential as supplementary food by evaluating their antioxidant activity and approximate chemical composition. Berries of E. conferta are a richer source of carotene, ascorbic acid, protein, and magnesium, whereas berries of C. carandus are rich in sugars, lipids, iron, and magnesium. The antioxidant properties of the berries and a comparative account on their performance using DPPH and FRAP assay was studied. Both assays revealed high activity in the peel extract of berries of C. carandus. The LC-MS/MS profile of C. carandus reveals the presence of eleven different polyphenolic compounds while E. conferta had only four of these compounds.

We determined the effect of Elaeagnus angustifolia extract on chondrogenesis and osteogenesis in mouse embryo limb buds in vitro and in vivo. Limb bud mesenchyme from day 12.5 embryos were used for high-density micromass cultures. Water/alcohol extract was added to culture media at 10, 100, 1000 and 10000 μg/L. Cytotoxicity was tested with neutral red. Chondogenesis was detected by alcian blue and osteogenesis was detected by alizarin red S and alkaline phosphatase activity. For in vivo experiments, 40 pregnant mice were given 0.5, 5.0 or 50.0 mg/kg of the extract between days 8 and 18 of gestation. Embryos were stained with alizarin red S and alcian blue to measure femur and ossified region lengths. Total bone mass volume was measured stereometrically. Data were compared with ANOVA and LSD. In limb bud cultures 10 μg/mL of extract reduced chondrogenesis but not osteogenesis. Higher concentrations had no effect on chondrogenesis or osteogenesis. In pregnant mice 50 mg/kg of the extr...

The present study was conducted to investigate the histological changes and wound healing effect of aqueous extract of Elaeagnus angustifolia. After creating full-thickness skin wounds on the back of 45 male Sprague-Dawley rats they were randomly divided into three groups. Treated group received the extract, positive control group were treated with mupirocin ointment 2% and control group did not receive any treatment. Wound healing rates were calculated on days 3, 5, 8, 10, 12 and 15 post-wounding and the wound tissues were harvested at 5, 10, and 15 days for histological analysis and hydroxyproline content measurement. The results indicated a significant increase in the percentage of wound contraction and hydroxyproline content in the treated group comparing to the control and positive control groups. A significant increase in the assigned histological scores was observed at 10 and 15 days in the treated and positive control groups compared to the control group. The results demonst...

Oxidant effects of nicotine in the central nervous system is not clear. The aim of this study was to investigate whether nicotine induces oxidative stress in rat brain, and if it does, to test the effects of Hippophea rhamnoides L. extract (HRe-1) and also vitamin E as a positive control. The groups were: nicotine [0.5 mg/kg/day, intraperitoneal (i.p.)]; nicotine+vitamin E [75 mg/kg/day, intragastric (i.g.)]; nicotine+HRe-1 (250 mg/kg/day, i.g.); and control group (receiving only vehicles). There were eight rats per group and supplementation period was 3 weeks. Malondialdehyde (MDA) level was increased by nicotine in brain tissue, which was prevented by vitamin E whereas not affected by HRe-1. Brain tissue glutathione S-transferase activities of nicotine administered and HRe-1 supplemented groups were lower than control and vitamin E supplemented groups, while glutathione peroxidase (GSH-Px) activities of vitamin E and HRe-1 supplemented groups were lower than the nicotine administe...

Migrations from the Qinghai-Tibetan Plateau (QTP) to other temperate regions represent one of the main biogeographical patterns for the Northern Hemisphere. However, the ages and routes of these migrations are largely not known. We aimed to reconstruct a well-resolved and dated phylogeny of Hippophae L. (Elaeagnaceae) and test hypothesis of a westward migration of this plant out of the QTP across Eurasian mountains in the Miocene. We produced two data matrices of five chloroplast DNA (cpDNA) and five nuclear DNA markers for all distinct taxa of Hippophae. These matrices were used to reconstruct phylogenetic relationships in the genus. In dating analyses, we first estimated the stem node age of Elaeagnaceae using five fossil records evenly distributed across a tree of Rosales. We used this estimate and two fossil records to calibrate the cpDNA and nDNA phylogenies of Hippophae. The same phylogenies were used to reconstruct ancestral areas within the genus. The monophyly of Hippophae, all five species, and most of subspecies was strongly supported by both plastid and nuclear data sets. Diversification of Hippophae likely started in central Himalayas/southern Tibet in the early Miocene and all extant distinct species had probably originated by the middle Miocene. Diversification of Hippophae rhamnoides likely started in the late Miocene east of the QTP from where this species rapidly expanded to central and western Eurasia. Our findings highlight the impact of different stages in uplift of the QTP and Eurasian mountains and climatic changes in the Neogene on diversification and range shifts in the highland flora on the continent. The results provide support to the idea of an immigration route for some European highland plants from their ancestral areas on the QTP across central and western mountain ranges of Eurasia in the late Miocene.

In an attempt to investigate new strategies aimed at reducing inflammation in osteoarthritis, the anti-inflammatory effect of Elaeagnus angustifolia L. as a complementary treatment was evaluated in females with knee osteoarthritis. In this clinical trial, 90 females with mild to moderate osteoarthritis were assigned to two intervention and one placebo groups. In addition to the conventional therapy, the patients in intervention groups received 15g/day of E. angustifolia L. medulla and whole fruit powders respectively for 8 weeks. The levels of tumor necrosis factor-alpha (TNF-α), interleukine-1β (IL-1β), interleukine-10 (IL-10), matrix metalloproteinase-1 (MMP-1) and -13 (MMP-13) were measured with human ELISA kits. Paired t-test and ANOVA were used for statistical analysis. The statistically significant decrease was observed in the mean levels of serum TNF-α in the medulla (0.004) and whole fruit (0.001) groups after 8 weeks of supplementation. In contrast to the placebo group, the...
