A count is not a conclusion and a tier is a study design, not a verdict. Everything listed here is laboratory or animal work, which does not show an effect in people. Each paper is listed with what it measured on the page below. See the research index for how papers are tiered.
This entry and asana describe the same drug, Pterocarpus marsupium, under different names. Both pages are kept because both names are in use, and each is cited as itself.

4. Pterocarpus marsupium extract extends replicative lifespan in budding yeast.
Authors: Lee Mitchell B, Kiflezghi Michael G, Tsuchiya Mitsuhiro et al. Journal: GeroScience (2021) PMID: 34297314
As the molecular mechanisms of biological aging become better understood, there is growing interest in identifying interventions that target those mechanisms to promote extended health and longevity. The budding yeast Saccharomyces cerevisiae has served as a premier model organism for identifying genetic and molecular factors that modulate cellular aging and is a powerful system in which to evaluate candidate longevity interventions. Here we screened a collection of natural products and natural product mixtures for effects on the growth rate, mTOR-mediated growth inhibition, and replicative lifespan. No mTOR inhibitory activity was detected, but several of the treatments affected growth rate and lifespan. The strongest lifespan shortening effects were observed for green tea extract and ber…

6. Anti-cataract activity of Pterocarpus marsupium bark and Trigonella foenum-graecum seeds extract in alloxan diabetic rats.
Authors: Vats V, Yadav S P, Biswas N R et al. Journal: Journal of ethnopharmacology (2004) PMID: 15234767
Long-term complications are frequently encountered in diabetes mellitus and are difficult to treat. This study was undertaken to assess the effect of three antidiabetic plants on the development of cataract in rats. An aqueous extract of Pterocarpus marsupium Linn bark (PM, Hindi name: Vijaysar) (1 g kg(-1) day(-1)), Ocimum sanctum Linn leaves (OS, Hindi name, Tulsi) (200 mg kg(-1) day(-1)) and alcoholic extract of Trigonella foenum-graecum Linn seeds (FG, Hindi name, Methi) (2 g kg(-1) day(-1)) were given to alloxan (120 mg kg(-1)) diabetic rats until the development of cataract. Serum glucose and body weight were monitored at regular intervals while cataract was examined through naked eye as well as slit lamp at 75, 100 and 115 days after alloxan administration. Administration of all the…
7. Pterocarpus marsupium Roxb. heartwood extract synthesized chitosan nanoparticles and its biomedical applications.
Authors: Manne Anupama Ammulu, K Vinay Viswanath, G Ajay Kumar et al. Journal: Journal, genetic engineering & biotechnology (2020) PMID: 32627099
The point of the present investigation was to blend effective chitosan nanoparticles (CNPs) loaded with Pterocarpus marsupium (PM) heartwood extract and evaluate its biomedical applications. Various plant extract concentrations (PM-CNPs-1, PM-CNPs-2, PM-CNPs-3) are used to synthesize chitosan nanoparticles and optimized to acquire a stable nanoparticle formulation. The entrapment efficiency and in vitro release studies of the plant extract encapsulated in CNPs are estimated. The PM-loaded CNPs were characterized by X-ray diffraction, dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesized chitosan nanoparticles were evaluated for their alpha-amylase inhibitory activity a…
Keywords: Alpha-amylase inhibitory activity, Anti-inflammatory activity, Chitosan nanoparticles, Pterocarpus marsupium

Literature indexed in PubMed that concerns this subject, grouped by study type. A paper appearing here is a record of what has been published, not evidence that the subject works, and laboratory or animal results do not transfer to people. Study titles link to PubMed so you can read the source rather than take our word.
