  1. 1. 2012 Banaba - Lagerstroemia speciosa LMunchausia speciosa Linn.Lagestroemia reginae RoxbBanaba is also knows as:Agaro, Mitla, Bugarom, Nabulong, Pamalauagon, Duguam, Pamarauagon, Kauilan,Parasabukung, Makablos, Tabangau, TauagnauBanaba is a flowering plant that grows in warm climate like the Philippines, India and others.Banaba is widely used in the Philippines and as herbal medicine for diabetes. While in India,Banaba is also used in Ayurvedic medicine for the treatment of diabetes. The Banaba leaves andflowers contain corrosolic acid, a substance being studied for its insulin like effect of loweringthe glucose in the body. Banaba is also being studied as a weight-loss supplement for its abilityto delay or reduce the absorption of carbohydraes. Banaba is also rich in vitamins and mineralsincluding zinc and magnesium.

  2. 2. 2012Banaba is a tropical flowering tree that grow up to 10 meters high. Banaba has large greenoblong leaves that is about 3 inches in width and 7 inches in length. The flowers or Banaba areracemes and colored pink to lavender. Banaba bears nut-like fruits that are arranged in largeclumps.A profusion of large, bright pink to lavender blooms appear in dense, foot-long, terminalpanicles, making Banaba tree a spectacular specimen to look at. Putting out brilliant displays ofthe glorious bright flowers, the tree attracts large numbers of bees, butterflies and birds.Furthermore, a well grown tree may flower twice a year. Due to which, it will stand out in everygarden and is a beautiful landscape tree. The Banaba tree can start flowering as early as threeyears of age.Banaba is a drought tolerant species which is easily cared in the garden or landscape with reallya low maintenance. It will grow in full sun on a wide range of well-drained soils but is not salt-tolerant. It coppices freely and is easily propagated by seeds, cuttings, root suckers.Banaba has dense and wide spreading root system. Hence the tree is valued for erosion control.The hardy tree can even be utilised for reforestation of degraded hills.Being one of the most beautiful trees, moreover, this tree is also medicinally valuable & famousin Ayurvedic medicine. Banaba can be used to treat number of ailments such as urinary tractinfections, blood pressure & even type II diabetes mellitus. It is also believed to have anti-diabetic & weight reducing properties. Technically, the active principle is considered to becorosolic acid, which promotes glucose transport or utilization in the body cells. The currentthinking is that Banaba can lower glucose independent of pancreatic insulin. This makes theactive principle of the tree a natural form of insulin from plants.

  3. 3. 2012served as a health drink. There are no known side effects or toxic reactions of Banaba. In fact, ithas been reported that it can help detoxify the body and protect the liver.AbstractThe leaves of Lagerstroemia speciosa (Lythraceae), a Southeast Asian tree more commonlyknown as banaba, have been traditionally consumed in various forms by Philippinos fortreatment of diabetes and kidney related diseases. In the 1990s, the popularity of this herbalmedicine began to attract the attention of scientists worldwide. Since then, researchers haveconducted numerous in vitro and in vivo studies that consistently confirmed the antidiabeticactivity of banaba. Scientists have identified different components of banaba to be responsiblefor its activity. Using tumor cells as a cell model, corosolic acid was isolated from the methanolextract of banaba and shown to be an active compound. More recently, a different cell modeland the focus on the water soluble fraction of the extract led to the discovery of othercompounds. The ellagitannin Lagerstroemin was identified as an effective component of thebanaba extract responsible for the activity. In a different approach, using 3T3-L1 adipocytes as acell model and a glucose uptake assay as the functional screening method, Chen et al. showedthat the banaba water extract exhibited an insulin-like glucose transport inducing activity.Coupling HPLC fractionation with a glucose uptake assay, gallotannins were identified in thebanaba extract as components responsible for the activity, not corosolic acid. Penta-O-galloyl-glucopyranose (PGG) was identified as the most potent gallotannin. A comparison of publisheddata with results obtained for PGG indicates that PGG has a significantly higher glucosetransport stimulatory activity than Lagerstroemin. Chen et al. have also shown that PGGexhibits anti-adipogenic properties in addition to stimulating the glucose uptake in adipocytes.The combination of glucose uptake and anti-adipogenesis activity is not found in the currentinsulin mimetic drugs and may indicate a great therapeutic potential of PGG.IntroductionType 2 diabetes has developed into a worldwide epidemic. Ironically, the dramatic increase inthe prevalence of type 2 diabetes can be attributed to the rapid economic development andcorrelated to changes in lifestyle within the last 50 years. Type 2 diabetes is closely associatedwith obesity. Up to 90% of the patients in the US with type 2 diabetes are either overweight orobese. It seems likely that the readily available high calorie food and a sedentary life style aremajor causes for obesity. Obesity contributes to insulin resistance and type 2 diabetes.Reducing obesity and stopping weight gain constitutes a way to slow down the rate ofoccurrence of type 2 | +91 841 888 5555
  4. 4. 2012Type 2 diabetes is caused by insulin resistance, which is defined as defective insulin signalingand a decreased insulin efficiency to induce glucose transport from the blood into key targetcells such as muscle and fat (adipocyte) cells. In general, obesity leads to hyperglycemia, whichin turn leads to and exacerbates insulin resistance. Insulin resistance, if not treated, results inhyperinsulinemia and eventually leads to full blown type 2 diabetes. Obesity or excessiveadiposity, particularly visceral adiposity, contributes to and worsens insulin resistance. Mostantidiabetic drugs are hypoglycemic or anti-hyperglycemic (blood glucose level reducing).However, most of these drugs are, to different extents, weight gain promoting (adipogenic).Thus, these drugs treat one of the key symptoms of type 2 diabetes, hyperglycemia, butexacerbate the condition of being overweight or obese, one of the leading causes of type 2diabetes. Therefore, while these drugs are beneficial over the short term, they are not optimalfor long term health of type 2 diabetic patient. The most desirable situation would be thedevelopment of new types of antidiabetic drugs that are either hypoglycemic or anti-hyperglycemic without the side effect of promoting weight gain (adiposity).

  5. 5. 2012Lagerstroemia speciosa - BanabaLagerstroemia speciosa , also called banaba in the Tagalog language of the Philippines, is atropical plant found in many parts of Southeast Asia including the Philippines, Vietnam,Malaysia and southern China. It is a tree that can grow as tall as 20m. Despite growing inseveral countries, only in the Philippines are the dried and shredded banaba leaves known to beused as a treatment for diabetes and kidney disease. It is not clear if banaba plants grown indifferent countries are equally effective in the treatment of diabetes.Corosolic Acid and Lagerstroemin—The Most Effective Antidiabetic Compounds in BanabaExtract?In 1993, a group of scientists from Hiroshima University used an Ehrlich ascites tumor cell linecoupled with a bioassay guided fractionation to screen compounds isolated by HPLC frombanaba extract in order to identify the effective antidiabetic component. Corosolic acid (2α-hydroxyursoloic acid) was identified as the effective compound in the methanol extract ofbanaba leaves in a glucose uptake assay. However, this result should be considered withcaution since the tumor cell line used in this study is a very unusual and unconventional cell linefor diabetes studies or antidiabetic compound screening. Furthermore, the result could notexplain the discrepancy that both the banaba water extract and the methanol extract wereactive in antidiabetic and anti-obesity animal studies since corosolic acid only exists in themethanol | +91 841 888 5555
