This invention relates to the field of honeycomb structure technology, specifically to a biomimetic reinforced chiral honeycomb structure. The structure comprises multiple periodically arranged chiral honeycomb basic units, each consisting of a ring and multiple ligaments connecting the rings. At least some of the ligaments have circular biomimetic reinforcing nodes, the diameter of which is larger than the thickness of the ligament and is integrally connected to it. This invention simulates the localized reinforcement structure of the enlarged bamboo nodes in *Phyllostachys edulis* by locally setting biomimetic reinforcing nodes in the ligaments, significantly improving the bending stiffness and load-bearing capacity of the ligaments with relatively low added mass, resulting in higher plateau stress in the structure. This invention has a simple structural form, is relatively easy to manufacture, and can be extended to other bending-dominant honeycomb structures.

The application discloses a kind of InDel marker fingerprint of wild Phyllostachys annamica strain, belong to red-to bamboo cane strain detection technical field, solve the problem that existing technical means cannot accurately identify wild red-to bamboo cane strain, the construction of the InDel marker fingerprint of the wild red-to bamboo cane is by genome DNA extraction, construct amplification system and amplify genome DNA, and the electrophoresis detection of amplification product, to obtain the InDel marker fingerprint of red-to bamboo cane strain, this fingerprint is used as standard atlas, the electrophoresis band in atlas is marked as 1; Lower band is marked as-1; Two bands are marked as 2;The InDel marker fingerprint of the wild red-to bamboo cane strain obtained by the above numbering step is-1, 2, 2, 2, -1, 1, -1, 1, 2, 2, subsequent unknown red-to bamboo cane strain is compared by constructing fingerprint, and the obtained fingerprint is compared with standard atlas.

The application discloses a kind of for non-destructive fast evaluation of bamboo physical mechanics property prediction model construction method, mainly including collecting the growth information of target bamboo and the positioning information of the sample site where it is located;The bamboo culm of target bamboo is determined for physical mechanics property, and the measured physical mechanics property data is obtained;Correlation analysis is carried out on growth information, positioning information and measured physical mechanics property data, and the index significantly related to physical mechanics property is selected as model input variable;Based on model input variable and measured physical mechanics property data, the prediction model for predicting the physical mechanics property of bamboo is constructed.The application introduces regional grouping effect and spatial autocorrelation structure when establishing the correlation model of bamboo culm growth character and bamboo physical mechanics property, so that the final prediction model can non-destructively determine the growth character of bamboo, quickly evaluate the physical performance of bamboo, and then greatly improve the grading utilization and high-value processing efficiency of different quality bamboo resources.

This invention relates to a method for preparing polysaccharides from *Phyllostachys edulis* root with antioxidant and neuroprotective activities, and is a method for preparing natural drugs. The invention involves reflux extraction of pulverized *Phyllostachys edulis* root with ethanol to remove small molecules, followed by extraction with hot water reflux to obtain crude polysaccharides. The crude polysaccharides are then purified through a series of separation and purification processes, including protein removal, depigmentation, and column chromatography, to obtain four new natural polysaccharides: PPLR-W, PPLR-1, PPLR-2, and PPLR-3. The natural polysaccharides prepared by this invention lay the foundation for the development of antioxidant-related drugs and clinical research on the prevention or treatment of neurodegenerative diseases. The four new *Phyllostachys edulis* root polysaccharides possess DPPH and ABTS free radical scavenging abilities and exhibit significant neuroprotective effects against hydrogen peroxide-induced SH-SY5Y cell damage models.

This invention relates to a shampoo and conditioner composition containing extract of *Phyllostachys edulis* and its preparation method. The shampoo and conditioner composition of this invention includes extract of *Phyllostachys edulis*, extract of patchouli leaf, surfactant, moisturizer, hair conditioner, skin conditioner, preservative, fragrance, pH adjuster, and deionized water. By rationally constructing the system architecture of the shampoo and conditioner composition, using extract of *Phyllostachys edulis* as the main active ingredient, combined with patchouli leaf extract, the combination of the two can effectively improve the oil control and dandruff removal effect of the shampoo and conditioner composition. The resulting shampoo and conditioner composition has a moderate scalp cleansing and conditioning effect, is safe and gentle, and has a good foaming feel. After use, the combability of dry and wet hair is significantly improved, which can delicately nourish hair strands, smooth damaged hair cuticles, restore the hair's moisture and texture, and improve frizz and tangles.
