The Banaba Leaf contains a triterpenoid compound called corosolic acid to help stimulate glucose transport into cells. Corosolic Acid plays a role in regulating levels of blood sugar and insulin in the blood.
The extract contains a triterpenoid compound called corosolic acid - that action by stimulating glucose transport into cells. Fluctuations in blood sugar and insulin are related to appetite, hunger and various food cravings - particularly craving for carbohydrates such as bread and sweets. By keeping blood sugar and insulin levels in check, it may be an effective for promoting weight loss.
Banaba Leaf contains Corosolic Acid to help stimulate glucose transport into cells. Corosolic Acid plays a role in regulating levels of blood sugar and insulin in the blood. Transporting glucose into cells is critical for providing the energy necessary for the cells to carry out vital functions. Compound that stimulate glucose transport help support healthy blood sugar levels.
Fluctuations in blood sugar and insulin are related to appetite, hunger and carbohydrate food cravings, particularly for breads and sweets. By controlling these cravings, it may provide a healthy support for weight control, leading to a leaner and more slender body through appetite control, sugar reduction and promotes healthy blood cholesterol levels.
Researchers have isolated an active ingredient in the banaba
leaf called corosolic acid which was originally thought to be "the"
blood sugar regulating substance in the leaf. Other researchers have
found that corosolic acid may not be the only active ingredient in
banaba leaves. A study published in the journal Planta Medica in 2001
compared a whole-leaf extract of banaba with insulin in cell cultures.
The researchers concluded that the whole herb has a glucose lowering
effect. Another study reported that banaba leaf extract contains at
least three active ingredients that effect blood sugar.
In animal studies, administration of banaba leaf extract resulted in a
significant decrease of blood glucose. The same studies suggest that
corosolic acid may stimulate glucose transport into tissue. In other
animal studies, administration of banaba leaf extract resulted in
reduced weight gain, reduced triglyceride accumulation and reduced
adipose tissue, with no changes in diet. In noninsulin-dependent
animals, administration of banaba leaf extract resulted in suppressed
blood plasma glucose, lower serum insulin and lower urinary excretion
In clinical studies conducted by Dr William Judy and associates at the
Southeastern Institute of Biomedical Research in Bradenton, Florida, a
one per cent corosolic acid extract of banaba leaf reportedly reduced
serum glucose 20-30% in people with Type II diabetes, but did not reduce
serum glucose in healthy individuals.
In a prior study, some of the same researchers observed that
individuals receiving the corosolic acid extract had an increased
tendency toward weight loss… an average of about 3.2 pounds.
Banaba is a tropical deciduous evergreen that is native to East Asia, flowering tree that can grow to 18 m in height, with a 9 to 12 m spread. The large, oblong, dark-green, leathery leaves measure 5 to 10 cm wide by 12 to 30 cm long. The leaves turn an orange-red color in the fall. The flowers are pink to purple in color, giving way to oval, nut-like fruits. The bark of the tree is thin, mottled, and peeling.
Banaba leaves contain ellagic acid derivatives,ellagitannins, lagerstroemin, flosin B, and reginin A, which are all possible glucose transport enhancers. Lagertannins, beta-sitosterol, stigmasterol, campesterol, and some olefins have been found in banaba leaves and extracts. Lageracetal (1,1-Dibutoxybutane), 1-pentanol, ellagic acid, and corosolic acid (a triterpene) have been isolated from leaves.
16 amino acids, pyrogallol tannins, and lipids present in banaba leaf.
From the neutral fraction of hot ethanol extracts of banaba leaves, nonacosane, hentriacontane, tritriacontane, olefins, and esters of palmitic, daturic, stearic, arachinic, and behenic acids were identified.
