“…Bamboo leaves contain many active ingredients with medicinal benefits and more than 100 chemical compounds, including flavonoids and flavonoid glycosides, volatile components, phenolic acids, and polysaccharides. 1 Bamboo leaf flavonoids (BLF) have attracted considerable recent attention, with orientin (OT), homoorientin, vitexin (VT), and isovitexin (IsVX) representing the four primary forms. 2,3 Flavonoids can alleviate neuronal degeneration since they demonstrate activity in the central nervous system and successfully cross the blood-brain barrier, like Alzheimer's disease (AD).…”

BackgroundClinically, patients with dementia are at high risk of developing enteritis, especially those with AD. This study explored the potential therapeutic benefits of bamboo leaf flavonoids (BLF) for ulcerative colitis (UC) treatment in Alzheimer's disease (AD) mouse model.MethodsVarious methods were employed, including pathological staining of brain/colon tissue, inflammatory cytokine detection in serum, and oxidative stress indicator assessment to compare ulcerative enteritis (UC) injury in normal and AD mice and determine whether AD mice were susceptible to colitis. Then, the effects of BLF on UC and AD were investigated via several unique indices further to determine whether it alleviated colitis injury and possessed beneficial properties. Moreover, four main components of BLF were utilized to treat primary colon epithelial cells and neuron cells to compare their effects in alleviating inflammation and oxidation. Furthermore, homoorientin embedded with ursolic acid was detected by HPLC and the in vitro release simulation experiments of the nanoparticles were performed.ResultsBLF complexes positively impacted ulcerative colitis by reducing disease activity, it also helped to reduce inflammation. Moreover, the BLF complexes decreased oxidative stress in the brain and colon tissues, indicating its potential as a neuroprotective agent. The flavonoid complexes reduced the expression levels of GFAP, Iba‐1, and Aβ in the brain tissue, highlighting its role in attenuating neuroinflammation and AD pathology. Additionally, the embedded homoorientin coated with ursolic acid showed stronger bioactivities when compared with the uncoated group.ConclusionThese results suggest that BLF complexes and its four main chemicals may be useful for treating AD‐ and UC‐related complications, the embedded homoorientin coated with ursolic acid even demonstrated stronger bioavailability than homoorientin. Considering BLF complexes were verified to suppress the progressions of AD and UC for the first time, and the embedded homoorientin was never reported in published articles, the present study might provide a new perspective on its potential applications.

Current techniques identifying herbal medicine species require marker labeling or lack systematical accuracy (expert authentication). There is an emerging interest in developing an accurate and label‐free tool for herbal medicine authentication. Here, a high‐resolution microfluidic‐based method is developed for identifying herbal species by protoplast subpopulations. Moso bamboo and henon bamboo are used as a model to be differentiated based on protoplast. Their biophysical properties factors are characterized to be 7.09 (± 0.39) × 108 V/m2 and 6.54 (± 0.26) × 108 V/m2, respectively. Their biophysical distributions could be distinguished by the Cramér–von Mises criterion with a 94.60% confidence level. The subpopulations of each were compared with conventional flow cytometry indicating the existence of subpopulations and the differences between the two species. The subsets divided by a biophysical factor of 8.05(± 0.51) × 108 V/m2 suggest good consistency with flow cytometry. The work demonstrated the possibility of microfluidics manipulation on protoplast for medication safety use taking advantage of dielectrophoresis. The device is promising in developing a reliable and accurate way of identifying herbal species with difficulties in authentication.

“…When endogenous and exogenous antioxidants fail to counteract free radicals, a condition of oxidative stress is generated, resulting in cellular damage and related diseases [ 16 ]. Many natural compounds rich in bioactive molecules, including bamboo, are potential antioxidants, able to protect against reactive oxygen species (ROS) and, ultimately, ameliorate oxidative stress–related diseases, such as cancer, cardiovascular and neurodegenerative diseases and inflammatory disorders [ 17 , 18 , 19 ].…”

Anti-Inflammatory and Antioxidant Effects of Leaves and Sheath from Bamboo (Phyllostacys edulis J. Houz)

Bamboo (Phyllostacys edulis J. Houz) has become an emerging forest resource of economic and ecological significance with health benefits. Since the beneficial effects of the non-edible parts of bamboo have not been thoroughly explored, we characterized in this study bamboo leaf (BL) and sheath (BS) extracts. The total phenol and flavonoid content (TPC and TFC), antioxidant activity (ABTS, DPPH, FRAP and β-carotene bleaching test) and anti-inflammatory properties were determined. Leaves exhibited a TPC value of 73.92 mg equivalent (eq) gallic acid/g fresh weight (FW) and a TFC value of 56.75 mg eq quercetin/g FW. Ultra-High-Performance Liquid Chromatography (UHPLC) coupled with photo diode array detector (PDA) analysis revealed evidence for the presence of protocatechuic acid, isoorientin, orientin and isovitexin in BL, whereas BS was rich in phenolic acids. Both samples demonstrated a significant ability to scavenge radicals against ABTS·+, with an inhibitory concentration of 50% of 3.07 μg/mL for BL and 6.78 μg/mL for BS. At a concentration of 0.1 and 0.2 mg/mL, BS decreased reactive oxygen species production without hampering cell viability in HepG2 liver cells, while at the same concentrations, BL exhibited cytotoxicity in HepG2 cells. In addition, 0.1 and 0.2 mg/mL BS and BL reduced Interleukin-6 and Monocyte Chemoattractant Protein-1 production in human lipopolysaccharide-stimulated THP-1 macrophages, without affecting cell viability. These findings highlight the anti-inflammatory and antioxidant properties of BL and BS, corroborating their different potential applications in the nutraceutical, cosmetic and pharmaceutical industries.
