    摘要: The present invention relates to bioactive extracts its fractions and isolation of compound from Rauwolfia tetraphylla. The extracts and fractions are useful for the treatment of psychosis based on in-vivo validation on animal model and proportional binding affinities for dopaminergic-D2, Cholinergic (muscarinic) and Serotonergic (5HT2A) receptors for antipsychotic activity. The present invention relates to novel antipsychotic activity in the leaf alkaloids of Formula 1 and 2 named tetrahydroalstonine, 10-methoxytetrahydroalstonine, isoreserpiline, 10-derαethoxyreserpiline, 11-demethoxyreserpiline, reserpiline and α-yohimbine. The present invention also relates to processes for obtaining antipsychotic extracts as well as for the isolation of alkabids of formula 1 and 2 from the leaves of Rauwolfia tetraphylla. The present invention particularly relates to significant antipsychotic activity in the MeOH extract, ethylacetate and chloroform fractions of R. tetraphylla and in the isolated compounds α-yohimbine, reserpiline and in a mixture 10-demethoxyreserpiline and 11-demethoxyreserpiline in 1:1.5 ratios for treating psychosis without any extra pyramidal symptoms (EPS). 1.

    摘要: The invention provides a method for maximization of artemisinin yield of the plant Artemisia annua, said method comprising sowing seeds of Artemisia annua plant on raised bed nursery during second and third week of December and maintaining the moisture throughout; transplanting seedlings thus obtained bearing at least 5-15 leaves into the main field fertilized with fertilizer, preferably NPK @ 80,40,40 kg/ha to achieve a population density of 50,000 to 200,000 per ha followed by light irrigation in the second week of March and irrigation every fortnight thereafter; harvesting the crop four times by cutting the plant tops leaving 75-100 cm part of plant for further regeneration, the said harvests are performed in a manner that the first harvest is done in fourth week of May, second harvest in third week of July, third harvest in second week of September and fourth harvest in third week of October of each year; and at each harvesting time care is taken to care at least one green branch, and extracting artemisinin from the plant tissue immediately after each harvest.
