The Asparagus officinalis L. asparagine (Asn) synthetase (AS) promoter was analysed for elements responding to carbohydrate and senescence signals. Transgenic Arabidopsis thaliana L. plants containing deletion constructs of the -1958 bp AS promoter linked to the β-glucuronidase (GUS) reporter gene
Asparagus racemosus roots have been shown to enhance insulin secretion in perfused pancreas and isolated islets. The present study investigated the effects of ethanol extracts of A. racemosus roots on glucose homeostasis in diabetic rats, together with the effects on insulin action in 3T3
The high metabolic rate of harvested asparagus spears (Asparagus officinalis L.) causes rapid deterioration. To extend shelf life, we investigated the effect of sucrose treatment on asparagus during storage. Asparagus spears were treated with 3%, 5%, and 10% sucrose and stored at 2 °C for 20 h.
The freezing tolerance of asparagus (Asparagus officinalis L.) embryogenic cells, as determined by electrolyte leakage, was increased by the incubation of samples in medium containing 0.8 M sucrose. To elucidate the mechanism involved, we investigated the changes in soluble carbohydrates, cell
To assess the physiological aspects underpinning cultivar difference in asparagus (Asparagus officinalis L.) yield, diel carbon exchange, carbon partitioning and export and sucrose phosphate synthase (SPS) activity were examined in mature cladophyll tissue of two asparagus cultivars (ASP-69 and
The aim of this study was to investigate the roles of carbon partitioning and sucrose metabolism in regulating cultivar differences in spear yield in asparagus (Asparagus officinalis L.). In the two cultivars studied, maximum net photosynthetic rate (Amax) was positively correlated with sucrose
Asparagus (Asparagus officinalis L.) accumulates inulin and inulin neoseries-type fructans in root, which are synthesized by three fructosyltransferases-sucrose:sucrose 1-fructosyltransferase (1-SST, EC 2.4.1.99), fructan:fructan 1-fructosyltransferase (1-FFT, EC 2.4.1.100), and fructan:fructan
In asparagus (Asparagus officinalis L.), increased levels of asparagine (Asn) and Asn synthetase (AS) transcript are detected during foliar senescence and in harvested spears, possibly triggered by signals from a reduced supply of carbohydrate. To identify cis-elements mediating this regulation, the
Four novel basic peroxidases, named AaP-1, AaP-2, AaP-3, and AaP-4, were purified from Asparagus acutifolius L. seeds by cation-exchange and gel filtration chromatographies. The four proteins showed a similar electrophoretic mobility of 46 kDa while, by MALDI-TOF MS, different Mr values of 42758.3,
The accumulation of total water-soluble carbohydrate, and specifically sucrose and fructan, by excised leaves of Phormium tenax and P. cookianum (family Phormiaceae J. G. Agardh, order Asparagales) was investigated. Total water-soluble carbohydrate content of excised leaves of P. tenax and P.
Comparative study of the antiulcer and antisecretory activity of Asparagus racemosus Willd (Shatawari) and Withania somnifera Dunal (Ashwagandha) root extract with a standard drug, ranitidine, in various models of gastric ulcer in rats is presented. Ulcer was induced by the indomethacin (NSAID) and
Differential hybridization of a cDNA library constructed with poly(A)+ mRNA from 24 h starved maize (Zea mays L.) root tips, resulted in the isolation of a cDNA (called pZSS1) that was highly induced during glucose deprivation. The nucleotide sequence analysis of the full-length cDNA allowed its
A series of Sarsapogenin and Diosgenin derived steroidal constituents (1-12), isolated from Solanum xanthocarpum and Asparagus racemosus were screened for their ability to induce cell death and apoptosis of colon carcinoma cells. The carbohydrate moieties linked to the steroid backbones were found
The methanolic extract of the roots of Asparagus africanus Lam (Liliaceae) which contains mainly saponins and carbohydrate showed significant analgesic and anti-inflammatory activities (P<0.05) in the tail-flick/hot-plate test and egg albumen-induced rat paw oedema tests that were comparable to the
OBJECTIVE
To study the antisecretory and antiulcer activity of Asparagus racemosus Willd. (methanolic extract) and its action against indomethacin (a non-steroidal anti-inflammatory drug) plus pyloric ligation (PL)-induced gastric ulcers in rats.
METHODS
Indomethacin plus PL-induced gastric
