the diallel cross design is frequently utilized to obtain information on genetic effects, estimates of general and specific combining ability (gca and sca) and to identify promising heterotic combinations as well as heterotic patterns. in the present study, heterotic crosses were identified for specific alkaloids in opium poppy (papaver somniferum l.) following yan’s gge biplot model by use of ...

The tuber of Corydalis yanhusuo is a famous traditional Chinese medicine and found to have potent pharmacological effects, such as antinociceptive, antitumor, antibacterial, anti-inflammatory, and anti-depressive activities. Although there are several methods to be developed for the analysis and detection of the bioactive ingredients' alkaloids, so far, only few prominent alkaloids could be qua...

Objective: The present study was conducted to investigate antibacterial properties of fruit and flower of Peganum harmala. Material and Methods: Column chromatography, followed by preparative thin layer chromatography (TLC) was used for final purification. The structure of pure alkaloids was determined using spectroscopic methods (1H-N...

Two new alkaloids were isolated together with 16 known lupin alkaloids from the leaves and stems of Chinese Maackia amurensis. Their structures were determined by spectroscopic methods to be (-)-6alpha-methoxylupanine and (-)-5alpha-(12-cytisinylmethyl)-6alpha-hydroxylupan ine and identified by comparison with synthetic samples. The structures of lupin alkaloids were also related to the geograp...

Chopra and others (1927) have shown that the alkaloids of Holarrliena antidysenterica possess marked amcebicidal properties, and Ghosh and Ghosh (1928) have shown that the Indian species of H. antidysenterica contain, besides conessine, two other alkaloids which they named kurchicine and kurcliine, respectively. Ghosh and Bose (1932) isolated these alkaloids in pure form and showed that the alk...

Photosynthesis, Assimilates, C-Metabolism, M arine/Freshw ater Algae, Taxonomy The representatives of the major algal divisions including Chlorophyta, Rhodophyta and Heterokontophyta usually show specific patterns o f accumulated photoassim ilatory products. Among these compounds, the accumulated low-molecular weight carbohydrates such as mono­ saccharides, disaccharides, alditols (i.e. polyhyd...

Saccharides are polyhydroxy compounds, and their synthesis requires complex protecting group manipulations. Protecting groups are usually used to temporarily mask a functional group which may interfere with a certain reaction, but protecting groups in carbohydrate chemistry do more than protecting groups usually do. Particularly, protecting groups can participate in reactions directly or indire...
