ABSTRACT
The snow lotus is an endangered traditional Chinese medicinal herb. Saussurea involucrata, Saussurea laniceps, and Saussurea medusa, the three main snow lotus species (five herbs and two S. involucrata cell cultures), were selected for this study. Snow lotus (XLs) was extracted using 75 % (v/v) ethanol. Two reversed phase-high performance liquid chromatography-diode array detector methods were developed and validated for the determination of 10 representative components in XLs. The antioxidant efficacy of XLs and their components was investigated using DPPH, ABTS free radical scavenging, and ROS inhibition experiments. The results showed that the IC50 for DPPH scavenging ranged from 0.06-0.29â mg/mL for XLs and from 0.13-0.63â mg/mL for ABTS, and could downregulate ROS to varying degrees. The results of the antioxidant activity showed that rutin, quercetin, and isochlorogenic acid A contributed to the antioxidant capacity of XLs. The high content and activity of the cell cultures indicate that they can serve as an effective alternative to snow lotus, thus providing a theoretical basis for the selection of herbs and cell cultures to fulfil various needs.

OBJECTIVE: To investigate the value of Compound Xuanju Capsule in the treatment of type-III prostatitis-related sexual dysfunction. METHODS: We randomly divided 90 type-III prostatitis patients with sexual dysfunction diagnosed by NIH clinical criteria into an experiment group and a control group to be treated with Compound Xuanju Capsule and antibiotics, respectively. We analyzed the therapeutic results based on the scores on chronic prostatitis symptom index (CPSI), prostatitis-related sexual function index (PSFI ) and self-rating anxiety scale (SAS), and compared them between the two groups and with the baseline data. RESULTS: The degree of prostatitis-related sexual dysfunction was not correlated with that of prostatitis symptoms. Prostatitis symptoms and sexual function were significantly improved in the experiment group than in the control (P < 0.05), and the SAS score was markedly lower in the former than in the latter (P < 0.05). CONCLUSION: Compound Xuanju Capsule can not only alleviate the symptoms of type-III prostatitis, but also improve its related sexual dysfunction and anxiety.
