Bataw is a smooth, twining, climbing or trailing
vine, 4 to 6 meters long, often with smooth, usually purplish stems. Leaves are
long stalked, 3-foliate with inequilateral leaflets. Leaflets are entire, ovate, and 7 to 15 centimeters long.
Flowers are few to many, white to pink-purple in color, about 2 centimeters long, on erect, long peduncled racemes 15 to 25 centimeters long. Pods are oblong, flattened, purple-margined, flat, and elongated with a prominent
beak, about 7 to 12 centimeters long and 2 centimeters wide, containing 3 to 5 seeds.

• Stem Cell Preservation
cell preservation factor FRIL (Flt3 receptor-interacting lectin), a
plant lectin extracted from Dolichos lablab was found to preserve hematopoietic
stems cells in vitro for a month.(1)
Diet supplemented with D. lablab seeds showed a hypocholesterolemic
• Cholecystokinin Secretion:
A peptide derived from dolicholin, a phaseolin-like protein from D lablab
potently stimulated cholecystokinin secretion from enteroendocrine STC-1
cells and suppressed food intake. (3)
• Antimicrobial / Antifungal:
n-Hexane and chloroform extracts of Dolichos lablab exhibited significant antimicrobial and antifungal activity against B subtilis, S aureus, P aeruginosa, E coli and C albicans. (4)
• Antidiabetic / Seeds:
Study evaluated the antidiabetic activity of a methanolic extract of D. lablab seeds in STZ-Nicotimamide induced diabetic model. Results showed dose-dependent reduction of blood glucose, total cholesterol, and triglycerides. (7)
• Anti-Inflammatory / Antioxidant / Cytotoxicity:
Study evaluated the in vitro anti-inflammatory, antioxidant, and cytotoxic properties of methanol extracts of two Bangladesh bean pods, Lablab purpureus L. sweet 'white' and 'purple'. Results showed L. purpureus sweet 'white' and L. purpureus sweet 'purple' have significant anti-inflammatory activity as well as a potential source of natural antioxidants. L. purpureus sweet 'white' had concentration dependent potential cytotoxicity. (8)
• Effect on Iron Deficiency:
Study evaluated the effectiveness of D. lablab beans extracts against iron deficiency in rats. Results showed a significant increase in hemoglobin level. Standard drug used was ferrous sulfate. (9)
• Anti-Diabetic / Leaves: Study of ethanolic extract of leaves of D. lablab produced significant decrease of blood glucose level in alloxan-induced diabetes in rats. (11)
• Anti-Hyperglycemic / Anti-Hyperlipidemic: Study evaluated the antihyperglycemic and antihyperlipidemic activity of a methanol extract of D. lablab. Results showed lowering of blood glucose, serum lipids and liver enzymes in diabetic rats. Standard drug was glibenclamide. (13)
• Natural Coagulants / Bioremediation: As natural coagulants, Moringa oleifera, Cicer arietinum, and Dolchos lablab significantly improved the removal of turbidity and total coliforms from synthetic raw water. The natural coagulants reduced 89-96% of total coliforms. (14)
• Effect in Iron Deficiency Anemia: Study evaluated the effect of Dolichos lablab (bataw) beans extract against iron deficiency in wistar rats with induced anemia. Results showed a significant increase in hemoglobin level. (15)
• Natural Coagulants / Bioremediation of Water Turbidity: Study evaluated the efficacy of extracts of Dolichos lablab, Moringa oleifera and Cicer arietinum as natural coagulants for the clarification of water turbidity. The three test extracts showed significant efficacy in removing turbidity and total coliforms from synthetic raw water. (16)
• Galactoase- Specific Lectin: Study isolated a galactose-specific lectin from the seeds of D. lablab. Among various sugars tested for inhibitory activity of the lectin, galactoase was found to be a potent inhibitor. Rabbit polyclonal antibody to the purified lectin specifically reacted with the lectin subunits in Western blot analysis. (17)
• Stem Cell Preservation: A plant lectin, stem cell preservation factor FRIL (Flt3 receptor-interacting lectin), was extracted from D. lablab and found to preserve hematopoietic stem cells in vitro. FRIL can also preserve neural progenitor cells in vitro by inhibiting both cell proliferation and differentiation. (18)
• Dolichin / Antifungal / Antiviral: An antifungal protein was modified from the seeds of Dolichos lablab. The protein, designated dolichin, exhibited antifungal activity against Fusarium oxysporum, Rhizoctonia solani, and Coprinus comatus. Dolichin was capable of inhibiting HIV reverse transcriptase and alpha- and beta-glucosidases which are glycohydrolases implicated i HIV infection. (19)
• Natural Coagulant / Antifungal / Antiviral: Study using locally available natural coagulants—Moringa oleifera, Cicer arietinum, Dolichos lablab—showed significant improvement in removing turbidity and total coiforms from synthetic raw water. (21)
• Anti-Asthma: Dolichos lablab has been reported to cause smooth muscle relaxant activity. (22)
