Further study of constituents from the aerial parts of Asclepias tuberosa afforded twenty-two new steroidal glycosides along with tuberoside B(5) and G(5). These glycosides were confirmed to contain 8,12;8,20-diepoxy-8,14-secopregnanes, tuberogenin and its congeners, as their aglycones. The structure of each of these compounds was elucidated based on the interpretation of NMR and MS measurement...

      The present study was carried out to determine the hypoglycemic activity of the methanolic extract and solvent fractions (n-hexane and ethyl acetate) of Ruellia tuberosa in normal and alloxan-induced diabetic rabbits. Optimum dose of R. tuberosa for hypoglycemic activity was determined by oral administration of the methanolic extract (ME) to normal and diabetic ...

Alpha-glucosidase inhibitors currently form an important basis for developing novel drugs for diabetes treatment. In our preliminary tests, the ethyl acetate fraction of Phlomis tuberosa extracts showed significant α-glucosidase inhibitory activity (IC₅₀ = 100 μg/mL). In the present study, a combined method using Sepbox chromatography and thin-layer chromatography (TLC) bioautography was develo...

Isoflavonoid contents of different plant parts and callus tissues of the Indian Kudzu, Pueraria tuberosa (Roxb.ex.Willd.) DC are presented. The initial cultures were slow growing, associated with browning of the tissues. The production of four isoflavonoids (puerarin, genistin, genistein and daidzein) in the callus cultures of P. tuberosa was studied by manipulating the plant growth regulators ...

Cracids are medium to large frugivorous birds that are endemic to the Neotropics. Because of deforestation and overhunting, many species are threatened. The conservation of several species has relied on captive breeding and reintroduction in the wild, but captive populations may be inbred. Microsatellite tools can permit the construction of genetic pedigrees to reduce inbreeding, but only a few...

Functional foods provide health benefit beyond basic nutrition. Functional foods fortified with plant ingredients are well known. Ayurveda (Indian System of Medicine) has found several ways in which the medicinal benefits of herbs can be conveyed via certain foods as carriers. Milk is one such carrier which has been effectively used to deliver phytochemicals for targeted health benefits. Indian...

Background: Vidari (Pueraria tuberosa) has been used throughout ages as a tonic, rejuvenator and galactogogue. This was an analytical study carried out to authenticate raw drug Vidari. Aims: This study aims to determine the Phyto-chemistry of the Vidari tubers when collected as per the Ayurvedic Principles. Methods and Material: Vidari tubers were collected from akaashiya bhumi (~land predomina...
