What is Bamboo leaf Extract?

Bamboo leaves, as well as bamboo shoot shavings and their resin, all can be used for medicinal purposes. The leaves from the smallest species of bamboo known in the horticultural world as Lophatherum gracile are the most commonly used bamboo leaves in the making of herbal remedies. This particular type of leaf is dried after collection and can used in the treatment of such things like urinary tract retention when blood is present in a person's urine as well as fidgeting and fever. Leaves from a type of bamboo known as Pleioblastus amarus also known as the bitter bamboo leaf, a taller form of the plant which grows in Southern China, is also typically used to treat fidgeting and fever in addition to treating lung inflammation. The bamboo leaf is the only part of the bamboo plant that is not used in relieving phlegm. Not long ago it was discovered that leaves from other tall species of the plant known as Phyllostachys can be used as antioxidants. This comes from the fact that these leaves contain vitexin and orientin which serve as flavonoids a component that has properties which help to curb allergic reactions as well as inflammations and also help with circulation.

Chemical constituents of Bamboo leaf Extract

bamboo leaves extract are flavonoids, lactones and phenolic acids, with the flavonoids being mainly flavone glycosides, including orientin, homoorientin, isovitexin, vitexin and tricin. The lactones in the extract are mainly hydroxyl coumarin and its derivatives. The phenolic acids are mainly derivatives of cinnamic acid including chlorogenic acid, caffeic acid and ferulic acid. The bamboo leaves extract is intended to be used in dietary supplements applications in capsule form. Because of its water solubility, it can also be used in other nutraceutical products such as milk powder and nutraceutical beverages. It has also been added to regular foods such as rice and noodle to increase nutrition values.

Benefits of taking Bamboo leaf Extract supplements:

Traditional Chinese medicine

Bamboo leaf has a long history of food and medical application in China,and has recently been listed by Ministry of Health PRC into the list of natural plants with dual-purposes as food and drug.

Usefulness of bamboo leaves are disclosed for the first time in the book of Ming Yie Bie Lu, which is to remove phlegm and can suppress the cough and difficulty breathing. While other uses are able to neutralize toxic in the body.

Modern medicine

>A study showed that bamboo leaves many sleepy active substance that is flavonoids, polysaccharides, chlorophyll, amino acids, vitamins, etc. micro element which can reduce blood fat and cholesterol and may reduce the oxidation antioxidants, can be as anti-aging ingredient for skin, and can maintain the stamina body and prevent cardiovascular disease.

>According to health experts from Japan that the composition is very similar falvonoid bamboo leaf structure of hemoglobin. Therefore, bamboo leaves can be directly injected into a vein. Bamboo leaf flavonoids are also very safe and non toxic.

Abstract

Reactive oxygen species scavenging effect of Pleioblastus kongosanensis f. aureostriatus leaf extract against O2(-), OH and H2O2 were investigated by chemiluminescence methods in vitro. Bamboo grass leaves were extracted with 70% ethanol solution and sequentially partitioned with solvents in an order of increasing polarity. Among fractions of different polarity, BuOH and EtOAc fractions showed powerful scavenging activities than others, and showed better scavenging ability on OH than that of O2(-)and H2O2, with IC50 of 0.55μg/mL and 0.60μg/mL, respectively. Both OH-induced DNA damage model by chemiluminescence assay and plasmid pUC18 double-strand break model by agarose gel electrophoresis showed that BuOH and EtOAc fractions had remarkable concentration-dependent prevention effect on the OH-induced damage of DNA attribute to their good scavenging effects on ROS. Results from the compositional analysis of different fractions indicate that the flavonoids in the Pleioblastus kongosanensis f. aureostriatus leaf may be responsible for its ROS scavenging activity and DNA damage prevention ability.

Abstract

Interest in the antioxidant activity of bamboo leaves is growing. To discover new sources of natural antioxidants, a TLC bioautography method combined with a new image processing method was developed to evaluate the antioxidant activity of leaf extracts from 15 different species of bamboo. The results showed that the methanolic extract of Bambusa. textilis McClure possessed the highest antioxidant activity among the selected bamboo species. To rapidly identify the antioxidant compounds, the crude extract of B. textilis McClure was analysed by HPLC-UV, and HPLC-micro-fractionation of the extract was carried out. Based on TLC bioautography-guided fractionation, three antioxidant fractions were isolated from B. textilis McClure by preparative chromatography. These three antioxidant compounds were identified as isoorientin 4''-O β-D-xylopyranoside, isoorientin 2''-O-α-L-rhamnoside and isoorientin according to their UV, MS, and NMR data. The proposed TLC screening method could therefore be an easy way to evaluate the antioxidant activity of bamboo leaves, and the results achieved should prove very helpful for promoting their utilization, as B. textilis McClure can be considered a promising plant source of natural antioxidants.

Abstract

Bamboo leaves (Phyllostachys pubescens Mazel ex J. Houz (Poacea)) have a long history of food and medical applications in Asia, including Japan and Korea. They have been used as a traditional medicine for centuries. We investigated the mechanism of anti-inflammatory activity of a bamboo leaf extract (BLE) on tumor necrosis factor-alpha (TNF-α)-induced monocyte adhesion in human umbilical vein endothelial cells (HUVECs). Exposure of HUVECs to BLE did not inhibit cell viability or cause morphological changes at concentrations ranging from 1 µg/ml to 1 mg/ml. Treatment with 0.1 mg/ml BLE caused 63% inhibition of monocyte adhesion in TNF-α-activated HUVECs, which was associated with 38.4% suppression of vascular cell adhesion molecule-1 expression. Furthermore, TNF-α-induced reactive oxygen species generation was decreased to 47.9% in BLE treated TNF-α-activated HUVECs. BLE (0.05 mg/ml) also caused about 50% inhibition of interleukin-6 secretion from lipopolysaccharide-stimulated monocyte. The results indicate that BLE may be clinically useful as an anti-inflammatory or anti-oxidant for human cardiovascular disease including atherosclerosis.

Abstract

High-fat diet is a major causative factor of overweight and obesity, which are associated with an increased risk of neuropsychiatric diseases, such as anxiety and depression. In the present study, we investigated the protective effects of bamboo extract (BEX) on anxiety- and depression-like neurobehaviours in mice treated with a high-fat diet. Male mice with CD-1 genetic background were treated for 2 months with either a standard or a high-fat diet (10 or 45 % energy from fat, respectively), with or without the BEX supplement (11 g dry mass per 17 MJ). The anxiety levels of mice were evaluated using open-field and hole-board tests, and depression was measured using the force-swimming test. The anxiety responses of the animals were found significantly increased after the high-fat diet treatment, and this elevation was effectively abolished by the BEX supplement. The high-fat diet seemed to have an anti-depressive effect in mice at the tested time point, but the effect of the BEX supplement on the depression level of the animals was not conclusive. The high-fat diet significantly decreased total glutathione content in the blood while the BEX supplement increased glutathione oxidation. In summary, the present study shows that decreased total glutathione concentration in the blood co-occurred with a high-fat treatment, high anxiety level and low depression level in mice, and when supplemented in a high-fat diet, BEX had an anxiolytic effect in mice

Abstract

AIM OF THE STUDY:

Bamboo leaves are used as a component in traditional Chinese medicine for the anti-inflammatory function. Our previous studies have demonstrated that an ethanol/water extract from Phyllostachys edulis ameliorated obesity-associated chronic systemic inflammation in mice, and therefore relieving the symptoms of type 2 diabetes. The aim of this project was to further investigate the effects of this bamboo extract on hepatic biotransformation enzymes in both lean and obese mice, as an initial step in the toxicological evaluation of using this traditional medicine in obese/diabetic population.

MATERIALS AND METHODS:

Male C57BL/6J mice were randomized to 4 groups and fed standard (10% kcal from fat) diet with or without bamboo extract supplementation at a dose of 10 gram per kilogram diet (n=10 and n=9, respectively), or high fat (45% kcal from fat) diet with or without bamboo extract (n=8 and N=7, respectively). The dietary treatment lasted for 6 months. Subsequently, the activities and expression of the major Phase I and II hepatic biotransformation enzymes were assessed in subcellular fractions from murine livers.

RESULTS:

Three groups of mice, lean bamboo extract-supplemented, obese/diabetic, and bamboo extract-supplemented obese/diabetic, showed greater activities of cytochromes P450 1a2 and 3a11 compared to control but no changes in the expression level of these proteins. For Phase II enzymes, bamboo extract supplementation in lean mice caused decreased glutathione-S-transferase activity (-12%) and greater uridine diphosphate glucuronosyltransferase activity (+46%), but had no effect on sulfotransferase activity. Conversely, the obese/diabetic condition itself increased glutathione-S-transferase and uridine diphosphate glucuronosyltransferase activities, but decreased total sulfotransferase activity and sulfotransferase 2a1 expression.

CONCLUSIONS:

Bamboo extract and obesity/diabetes show significant independent effects on hepatic biotransformation as well as interaction effects in mice. These changes may alter the clearance of endo- and xenobiotics, including bamboo extract itself, hence this effect should be carefully considered in the medicinal application of bamboo extract as it has potential to alter its own metabolism and that of other medications concurrently administered to obese diabetic patients.

(Source-Laboratory of Microbiology and Oncology, Sojo University, 22-1, Ikeda 4-chome, Kumamoto 860-0082, Japan.)

Abstract

BACKGROUND:

Kumaizasa bamboo found in Hokkaido is used for traditional medicine in Japan. The cancer preventive effect of vigorous (multistep) hot water extract of Kumaizasa was examined in relation to immunological conditioning and free radical scavenging activity.

MATERIALS AND METHODS:

Cytokine induction in mice, free radical scavenging activity in vitro, and cancer preventive effect by oral administration of the vigorous extracts prior to tumor implantation or carcinogenesis by 7,12-dimethylbenz[a]anthracene (DMBA) were examined.

RESULTS:

In tumor inoculated mouse models (S-180 sarcoma, Meth-A fibrosarcoma, B16-F10 melanoma), the vigorous extracts from Kumaizasa bamboo leaves suppressed tumor growth and prolonged survival significantly. In the chemical carcinogenesis model suppression of cancer incidence on day 100, tumor size and survival time were significantly improved with the vigorous extract, at/or above 0.03% in the diet, when given two weeks prior to the administration of the carcinogen.

CONCLUSION:

The vigorous extracts of bamboo leaf show immunopotentiating and radical scavenging effects and administration prior to carcinogen exposure or tumor inoculation significantly suppresses tumor incidence and tumor growth and prolongs survival.
