Growth year is one of the important factors for the quality of Polygala tenufolia. In this study, primary metabolites and secondary metabolites were compared in 1, 2 and 3 years old P. tenufolia cultivated in Shaanxi Heyang. The samples were subjected to ultra-high performance liquid chromatography (UPLC)-quadrupole time-of-flight mass spectrometry (Q-TOF MS) and nuclear magnetic resonance (NMR) analysis, and the obtained data were analyzed using principal component analysis (PCA) and other statistical analysis methods. In addition, content and correlation of different metabolites were also calculated. The results showed no significance between main component contents in 2 year-old and 3 year-old P. Tenufolia, but 1 year-old was statistically different. The contents of primary metabolites, such as fructose, sucrose, and choline increased as time goes on, while glycine and raffinose decreased. The contents of secondary metabolites, such as onjisaponin Fg, polygalasaponin XXVIII, polygalasaponin XXXII increased, while polygalaxanthone III and parts of oligosaccharide multi-ester including tenuifoliose A, tenuifoliose C, tenuifoliose C2 and tenuifoliose H decreased with the extension of the growth years. Growth years has important impact on the quality of P. tenuifolia and the existing growing years of commodity P. tenuifolia have its scientific evidence. This study supplied a new method for the quality evaluation of Chinese medicinal materials.

Objective: To observe the clinical efficacy of electroacupuncture (EA) on Alzheimer's disease (AD). Methods: A total of 50 AD patients were randomly allocated into a Western medication (WM) group (n=25) and an acupuncture plus medication (APM) group (n=25). Patients in the WM group took oral huperzine A capsules. In addition to huperzine A capsules, patients in the APM group also received EA at Shenting (GV 24), Baihui (GV 20), Dazhui (GV 14), Fengfu (GV 16), Mingmen (GV 4) and Yongquan (KI 1). The needles on the above points were connected to G6805-Ⅱelectric stimulator [3 pairs: Shenting (GV 24) and Baihui (GV 20); Dazhui (GV 14) and Fengfu (GV 16); and bilateral Yongquan (KI 1)]. The needles were retained 25 min. The treatment was done once a day, and 10 times made up a course of treatment. The patients received a total of 3 treatment courses. There was a 3-day interval between two courses. The mini-mental state examination (MMSE) and Hasegawa dementia scale revised (HDS-R) were conducted before and after treatment. The clinical efficacies were evaluated when the treatment was completed. Results: Before treatment, there were no between-group statistical differences in MMSE and HDS-R scores (both P>0.05). After treatment, the MMSE and HDS-R scores in the APM group were significantly higher than those in the WM group (both P<0.05). The total effective rate in the APM group was 88.0%, versus 76.0% in the WM group, showing a statistical difference (P<0.05). Conclusion: EA is effective for AD and can improve clinical symptoms in AD patients.
