Lysosomal and microsomal acid phosphatase activity was estimated in midgut tissue of silkworm larvae, Bombyx mori L. (Lepidoptera: Bombycidae), after induced oxidative stress by D-galactose. The larvae were simultaneously were treated with ethanolic extracts of Bacopa monniera and Lactuca sativa to study their antioxidant properties. Lipid peroxidation and fluorescence was measured to analyze e...

Lactuca sativa, belonging to the Asteraceae family, is a leafy vegetable known for its medicinal properties. This study aimed to understand the mechanism of Lactuca sativa extract with respect to pharmacological action.We investigated the anxiolytic effects of hydro-alcoholic extract of leaves of Lactuca sativa on mice. The behavioral tests performed on mice models to assess anti-anxiety proper...

An AFLP data set comprising 95 accessions from 20 species of Lactuca s.l. (sensu lato) and related genera was generated using the primer combinations E35/M48 and E35/M49. In phenetic analyses of a data subset, clustering with UPGMA based on Jaccard's similarity coefficient resulted in the highest cophenetic correlation, and the results were comparable to those of a principal coordinates analysi...

Prickly lettuce (Lactuca serriola L.) is a problematic weed of Pacific Northwest and recently developed resistance to the auxinic herbicide 2,4-D. There are no publically available simple sequence repeat (SSR) markers to tag 2,4-D resistance genes in L. serriola. Therefore, a study was conducted to develop SSR markers from expressed sequence tags (ESTs) of 5 Lactuca species. A total of 15,970 S...

Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced norma...

traditionally, lactuca sativa (lettuce) has been recommended for its hypnotic property.the present study was planned to investigate sleep-prolonging effect of this plant. the hydroalcoholicextract (hae) of lettuce and its water fraction (wf), ethyl acetate fraction (eaf),and n-butanol fraction (nbf) were administrated (ip) to mice 30 min before the pentobarbitalinjection. moreover, both in-vivo...

Kinetin alleviates cycloheximide inhibition and oxygen alleviates chloramphenicol inibition of germination of lettuce seeds (Lactuca sativa L. cv Grand Rapids). The effect is not due to increased but rather a substitution for protein synthesis. A cytokinin and energy supply appear prime requirements for germination.

BACKGROUND Lactuca sativa (garden lettuce) is a popular salad herb. It has been in use in folk medicine since ancient times as both an appetite stimulant and as an aid to sleep. L. sativa seed oil (Sedan(®)) has demonstrated a pronounced sedative effect and potentiated the hypnotic effect of barbiturates in animal models. It also exhibited significant analgesic and anti-inflammatory activities....

A systematic collection of throughfall (rain passing through the canopies), stemflow (rain flowing over the stems), and soil percolates was carried out in a Acacia dealbata plantation during one year, and its allelopathic capacity was biotested using Lactuca sativa L. var. Great Lakes. The results showed an allelopathic effect related to flowers: Germination of L. sativa was inhibited 30% by th...
