Nutritional and medicinal information

 

Pharmaceutical significance

  1. The potential effects of aqueous extract of Pterocarpus marsupium (AEPM) on elevated inflammatory cytokine, tumor necrosis factor (TNF)-α in type 2 diabetic rats was investigated. Two doses were being tested, i.e., 100 and 200 mg/kg. Both doses of AEPM, decreased the fasting and postprandial blood glucose in type 2 diabetic rats. The 200 mg/kg had more pronounced effect on postprandial hyperglycemia as well as it modulated the inflammatory cytokine TNF-α. Rasayana property of P. marsupium not only proved its potential as an anti-diabetic but also improved the body weight of diabetic animals.

 

  1. The crude powder, ethanolic extract and aqueous, chloroform, hexane and n-butanol soluble fractions of ethanolic extract of heart wood of P. marsupium also proved its anti-diabetic properties. All the extracts except aqeous showed remarkable results in increasing the oral glucose tolerance post sucrose load. The ethanolic extract ofi also showed marked anti-dyslipidemic (imbalance of lipids) effects on high fat diet fed Syrian golden hamsters. Hence it can be concluded that, phenolic-C-glycosides present in P. marsupium heart wood are the phytoconstituents responsible for the anti-hyperglycemic activity and anti-diabetic activity of its heart wood.

 

Harvesting and preserving

Leaves could be collected from wild.

Its bark and latex could be stored

Flowering

September-October

How to grow it?

1. Sow the seeds in pots and allow them to germinate. Later plant them in the areas which are sunny and having well drained, deep, rich, light to medium soil.

2. It grows best in areas where the mean annual temperature falls within the range 22 - 34° C and prefers a distinct dry season. Rainfall requirement is 1,000- 1,500mm.

3. Prefers a pH in the range 6 – 7 and this species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen.

 

Method of storage:

Propagules are stored in the form of seeds

 

Other uses
