Introduction The Shell Islands of Yellow River Delta is one of the three largest old shell islands in the world; it is mainly formed by the shells and debris of shellfish living in the intertidal zone after their death, which are transferred by waves and piled near the high tide collection [1,2]. The beach ridge part of Shell Islands is definitely relatively high above sea level, and the underground water level is definitely low. Moreover, the shell sand dirt offers high porosity, the coarse sand content is the highest, and the retention precipitation ability is definitely poor. Coupled with the high regional evaporation-precipitation percentage, the seasonal water shortage is definitely serious, and the vegetation type is definitely prioritized, specifically xerophytic shrubs and natural herbs. (Pall.) Rehd is definitely a common shrub tree varieties in beach ridge zones [1,2]. is definitely a deciduous shrub belonging to the Euphorbiaceae family that has extremely strong adaptability and may endure chilly, drought, and barren conditions, we.e., sandy dirt [3]. develops approximately 1C2 m in height and offers clusters, twigs, and tree-shaped development. Its origins are used in traditional Chinese medicine [4, 5]. It is rich in securinega-type alkaloids, especially securinine, and contains active compounds, such as flavonoids, rutin, tannins, phenolic compounds, and various amino acids [6]. Pharmacological studies have shown that can promote blood circulation, unwind the muscle tissue and tendons, invigorate the spleen and kidney, and reduce rheumatic pains. Moreover, this shrub is effective for the treatment of neurasthenia, facial nerve paralysis, post-polio syndrome, dizziness, deafness, narcolepsy, impotence, and acute liver injury, and other diseases [7C10]. It possesses an extremely high software value [4]. In addition to the flower itself, several studies within the microorganisms in the ecological environment of Shell Islands have reported the presence of actinomycete genera in the dirt, specifically and sp. HDN13-307 [17]. Vincamine, a monoterpenoid indole alkaloid that significantly inhibits acetylcholinesterase activity was isolated from an oleander endophytic fungus sp. CH1 [18]. Endophytic fungi are widely distributed in many flower varieties across all flower organizations and play an important part in bio-antagonism and abiotic tensions.
