Bamboo leaves are considered as an important source of bioactive molecules. In this work, leaves from young bamboo (Phyllostachys pubescens Mazel) aged 3 months were subjected to aqueous extraction and 2% NaOH solution extraction followed by precipitation in ethanol-water medium with different ethanol concentrations. The dissolved hemicellulosic polysaccharides presented a total recovery of 67.83% based on the total hemicellulose content in bamboo leaves. Chemical analysis of the fractions was performed by sugar composition analysis, Fourier-transform infrared spectrometry, and 1D nuclear magnetic resonance imaging. The results revealed that all polysaccharide fractions contained xylose, arabinose, glucose, galactose, ribose, and uronic acid. The polysaccharides from young bamboo leaves mainly consisted of arabinoxylans, arabinogalactans, and non-cellulosic β-D-glucans having (1→3)- and (1→4)-glucosidic linkages. The content of these polysaccharides was found to vary among the fractions depending on the separation method. Finally, the thermal behavior was also discussed.

The ruins of the Imperial City of the Minyue Kingdom were an important site of the Minyue Kingdom during the Han Dynasty. Characteristic bronze arrowheads unearthed from the East Gate, with their exquisite craftsmanship, provide important physical evidence for studying ancient bronze casting technology and the military activities of that time. However, there is still a lack of systematic research on the alloy composition, casting process, and chemical stability of these arrowheads in long-term burial environments.

Objective: To observe the clinical efficacy of acupuncture combined with bamboo-based medicinal moxibustion in the treatment of chronic insomnia complicated with mild depressive state.
Methods: A total of 60 patients with chronic insomnia complicated with mild depressive state were randomly divided into an observation group and a control group, 30 cases in each group. The control group was treated with acupuncture at bilateral Zhaohai (KI6), Shenmen (HT7), Sanyinjiao (SP6), Anmian (Extra) and Sishencong (EX-HN1), Baihui (GV20), etc.

Cysteine-rich polycomb-like proteins (CPPs), pivotal transcription factors crucial for evolution of plants from germination to maturity, and adaptation to environmental stresses, have not yet been characterized within the context of Moso bamboo. The CPP gene family of Moso bamboo was identified through bioinformatics, and the structural and functional attributes of the gene, including its physicochemical properties, evolutionary relationships, and gene-protein structures, were revealed. Additionally, the current study also offers valuable information on the patterns of gene expression in bamboo shoots during the period of accelerated development.

Bamboo shoots, as the young bamboo stems, are rich in protein, fiber, vitamins, and minerals, as well as many bioactive substances beneficial to health, and are gaining in importance worldwide as a healthy food and dietary supplement. However, fresh bamboo shoots lignify rapidly after harvesting and contain cyanogenic glycosides, limiting the safe and healthy consumption of bamboo shoots. To this end, based on the changes in nutritional composition and the physiological properties of fresh and post-harvest bamboo shoots, factors affecting the preservation of post-harvest bamboo shoots are emphasized, including a series of physical and chemical regimes and various processing methods for post-harvest preservation.
