“…The freeze-dried B. multiplex , B. tuldoides , D. sublaevigata , G. levis , and S. brachycladum specimens in this study demonstrated the highest TFC, supporting the report by Soesanto [ 25 ], who noted that the freeze-dried extracts of B. vulgaris and G. apus shoots exhibited higher TFC, TPC, and DPPH than the oven-dried samples. Nonetheless, the microwave-dried B. vulgaris in this study recorded the highest TFC at 0.14 mg gallic acid equivalent (GAE)/g, slightly dissimilar from the freeze-dried extracts that exhibited the second highest TFC.…”

The therapeutic potential of bamboos has acquired global attention. Nonetheless, the biological activities of the plants are rarely considered due to limited available references in Sabah, Malaysia. Furthermore, the drying technique could significantly affect the retention and degradation of nutrients in bamboos. Consequently, the current study investigated five drying methods, namely, sun, shade, microwave, oven, and freeze-drying, of the leaves of six bamboo species, Bambusa multiplex, Bambusa tuldoides, Bambusa vulgaris, Dinochloa sublaevigata, Gigantochloa levis, and Schizostachyum brachycladum. The infused bamboo leaves extracts were analysed for their total phenolic content (TPC) and total flavonoid content (TFC). The antioxidant activities of the samples were determined via the 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and ferric reducing antioxidant power (FRAP) assays, whereas their toxicities were evaluated through the brine shrimp lethality assay (BSLA). The chemical constituents of the samples were determined using liquid chromatography–tandem mass spectrometry (LC-MS/MS). The freeze-drying method exhibited the highest phytochemical contents and antioxidant activity yield, excluding the B. vulgaris sample, in which the microwave-dried sample recorded the most antioxidant and phytochemical levels. The TPC and TFC results were within the 2.69 ± 0.01–12.59 ± 0.09 mg gallic acid equivalent (GAE)/g and 0.77 ± 0.01–2.12 ± 0.01 mg quercetin equivalent (QE)/g ranges, respectively. The DPPH and ABTS IC50 (half-maximal inhibitory concentration) were 2.92 ± 0.01–4.73 ± 0.02 and 1.89–0.01 to 3.47 ± 0.00 µg/mL, respectively, indicating high radical scavenging activities. The FRAP values differed significantly between the drying methods, within the 6.40 ± 0.12–36.65 ± 0.09 mg Trolox equivalent (TE)/g range. The phytochemical contents and antioxidant capacities exhibited a moderate correlation, revealing that the TPC and TFC were slightly responsible for the antioxidant activities. The toxicity assessment of the bamboo extracts in the current study demonstrated no toxicity against the BSLA based on the LC50 (lethal concentration 50) analysis at >1000 µg/mL. LC-MS analysis showed that alkaloid and pharmaceutical compounds influence antioxidant activities, as found in previous studies. The acquired information might aid in the development of bamboo leaves as functional food items, such as bamboo tea. They could also be investigated for their medicinal ingredients that can be used in the discovery of potential drugs.

“…Inhibits chemokine expression and pro-inflammatory cytokines (IL-17), inhibits infiltration of neutrophils and macrophages and inhibits inflammatory reactions mediated by cells T [13], [14]. Thus, the proatherogenic effects of IL-17 can be prevented so that tissue damage does not occur, and the number of monocytes that are drawn to the arterial wall has decreased so that the process of foam cell or foam cell formation can be reduced [10]. Thus, the higher the ratio between IL-17 levels and IL-10, the higher the risk of atherosclerosis.…”

“…The atherogenic feed used is a standard feed supplemented with cholesterol made from 0.5% egg yolk and 5% pork oil supplemented with a standard 100% feed. Cholesterol flour is made from chicken egg yolks dried in an oven at 60°C for 24 h to dry and blend until smooth [10]. The experimental animals used were 4 months old New Zealand White rabbits weighing between 2000 and 2500 g, male sex.…”

BACKGROUND: Atherosclerosis begins with injury to the endothelial, progressive, and increases by 3% per year since the age of a person passes 20 years. The ratio of the number of pro and anti-inflammatory cytokines can describe the development of the process of atherosclerosis so that the higher the ratio will increase the chance of atherosclerosis. AIM: The purpose of this study was to examine the effect of Bamboo shoot Gigantochloa apus (BSGA) extract on decreasing interleukin-17 (IL-17)/IL-10 level ratios in New Zealand White rabbits given an atherogenic diet. METHODS: This study uses BSGA extract freeze-dried aged 1–2 weeks and New Zealand White rabbits. Atherogenic feed uses 0.5% egg yolk and 5% pork oil which is added to the standard feed. Randomized pre- and post-test with control group design by dividing into four groups were used in this study. RESULTS: The mean ratio of IL-17 levels with IL-10 between before and after (p < 0.005) in all groups showed a significant difference. There was a trend of increasing the ratio between IL-17 levels and IL-10 in all groups and the highest increase occurred in the control group which was 420%. CONCLUSION: The higher the dose of BSGA extract administration could reduce the ratio between IL-17 levels and IL-10 and there is a correlation with a negative linear pattern between IL-10 and IL-17 with p = 0.034 which means that higher levels of IL-10 will reduce IL-17 levels.

Dendrocalamus asper (Schult.) Backer is a large shrub native to Asia, Africa, and the United States that is also cultivated in Egypt. Total phenolics, flavonoids and antioxidants in different fractions showed that the ethyl acetate extract has the highest content 20.95 ± 1.29 GAE (Gallic acid equivalents) and 19.65 ± 0.77 (quercetin equivalents) with antioxidant 64%, respectively. HPLC analysis of D. aspera extract revealed presence of 14 and 11 phenolic acids and flavonoid compounds, respectively. Pyrogallol, Coumarin and gallic acid have been determined as 3981.7, 1139.8, and 1135.1 mg/100gm in the extract of D. asper extract, While Kaempferol -3-2-pcoumaroylglucos 4046.4 mg/100gm was the most predominant compounds in the extract of D. asper extract, Phenolic acids and flavonoids tentatively identification depends on Chemical and …
