Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...

The methanol extracts of the various plant parts were screened for anti-oxidant activity by thin layer chromatography using 2,2-diphenyl-1-dipicrylhydrazyl (DPPH) while in vitro antimicrobial evaluation was determined agar diffusion method and bioautographic technique Escherichia coli, Bacillus subtilis, Staphylococcus aureus Pseudomonas aeruginosa as test organisms; aqueous solvent served cont...

Abstract: The analysis of longevity can support decisions about the length seed lot storage until commercialization, since this characteristic implies maintenance viability over time. Seed is analyzed by p50 test, which expresses time to lose 50% initial viability. Seeds with high vigor and germination have greater physiological potential and, thus, a capacity maintain quality throughout period...

Abstract: The use of computational resources to assess the physiological potential seeds has attracted attention researchers and professionals in seed sector. aim this study was evaluate vigor cowpea using Vigor-S software (Automated Seed Vigor Analysis System), comparison information provided by traditional tests that are recommended for species. Seven lots cultivar BRS Guariba were used. They...

Seed dormancy and endozoochorous dispersal have important effects on population dynamics, i.e. seed bank formation, spatial and temporal bethedging, avoidance of crowding and decreased sib-competition. Seeds having primary dormancy do not germinate, even if adequate environmental and dispersal conditions are met, until an after-ripening period is completed. This study examined the effects on ge...

To evaluate deterioration of oat seeds during storage, we analyzed oxygen radicals, antioxidant enzyme activity, proline content, and gene transcript levels in oat seeds with different moisture contents (MCs; 4, 16, and 28% w/w) during storage for 0, 6, and 12 months (CK, LT-6, and LT-12 treatments, respectively) at 4°C. The germination percentage decreased significantly with higher seed MCs an...

Protein phosphatase 2A (PP2A) is a critical target to control cumulative oxidative stress and chronic inflammation during skin aging by reversible methylation of the C-terminal leucine PP2A catalytic subunit (PP2Ac). A novel, proprietary Activated-Grape Seed Extract (AGSE), enriched for PP2A-activating flavonoids, was recently developed, has demonstrated potent antioxidant anti-inflammatory act...

The western Ordos Plateau is a key area of shrub diversity and a National Nature Reserve of endangered shrub species in north-west China. Desert expansion is becoming the most important threat to these endangered species. However, little is known about the effects of sand burial on the dynamics of the shrub community. This study aims to investigate how the shrubs as a community and as different...

Immunosenescence is the degeneration of immunological organs and cells due to aging. Some plants fungi may have anti-aging benefits through regulating immunosenescence. In this study, mice were fed with two dietary supplement products: Zeng Jian Health Tonic (ZJ) contains extracts from Lentinula edodes, Poria cocos, Tremella fuciformis, cassia seed, Flammulina velutipes, Fructus lycii, chrysant...
