Abstract
Neurological diseases are complex diseases affecting the brain and spinal cord, with numerous etiologies and pathogenesis not yet fully elucidated. Tripterygium wilfordii Hook. F. (TWHF) is a traditional Chinese medicine with a long history of medicinal use in China and is widely used to treat autoimmune and inflammatory diseases such as systemic lupus erythematosus and rheumatoid arthritis. With the rapid development of modern technology, the two main bioactive components of TWHF, triptolide and celastrol, have been found to have anti-inflammatory, immunosuppressive and anti-tumor effects and can be used in the treatment of a variety of diseases, including neurological diseases. In this paper, we summarize the preclinical studies of triptolide and celastrol in neurological diseases such as neurodegenerative diseases, brain and spinal cord injury, and epilepsy. In addition, we review the mechanisms of action of triptolide and celastrol in neurological diseases, their toxicity, related derivatives, and nanotechnology-based carrier system.

Abstract
There are no non-hormonal male contraceptives currently on the market despite decades of efforts toward the development of "male pills". Here, we report that triptonide, a natural compound purified from the Chinese herb Tripterygium Wilfordii Hook F displays reversible male contraceptive effects in both mice and monkeys. Single daily oral doses of triptonide induces deformed sperm with minimal or no forward motility (close to 100% penetrance) and consequently male infertility in 3-4 and 5-6 weeks in mice and cynomolgus monkeys, respectively. Male fertility is regained in ~4-6 weeks after cessation of triptonide intake in both species. Either short- or long-term triptonide treatment causes no discernable systematic toxic side effects based on histological examination of vital organs in mice and hematological and serum biochemical analyses in monkeys. Triptonide appears to target junction plakoglobin and disrupts its interactions with SPEM1 during spermiogenesis. Our data further prove that targeting late spermiogenesis represents an effective strategy for developing non-hormonal male contraceptives.

Abstract
Activation of microglia is a critical pathological marker of Parkinson's disease. Activated microglia produces proinflammatory and neurotoxic factors, which cause neurons to induce neurodegeneration. Although it is believed that Chinese herbs, such as Tripterygium wilfordii Hook F, can ease inflammatory diseases, little is known about its benefit to neurodegenerative disease, like Parkinson's disease. In this study, we report the extract of Tripterygium wilfordii Hook F with a novel extraction method significantly protected dopaminergic neurons from LPS-induced degeneration in rat mesencephalic neuron-glia cultures. Cells pretreated with the extract have shown dose-dependent inhibition of LPS-induced TNFα and excessive NO production. More importantly, the total number of activated microglia was greatly reduced in these pretreated cells. Our results suggest that the extract of Tripterygium wilfordii Hook F has a strong bioactive function to diminish the pro-inflammatory factors, such as TNFα and NO. These data might also shed light for future neurodegenerative disease therapy.

Abstract
Wilfortrine, wilfordine, wilforgine and wilforine are four major bioactive sesquiterpene alkaloids in Tripterygium wilfordii Hook. F. The first analytical determination of the four major bioactive alkaloids is described. The four alkaloids are well-resolved within 15 min using the developed HPLC method. The identity of the analytes was confirmed by an HPLC-MS experiment, with all compounds being clearly assignable by atmospheric pressure chemical ionization (APCI) positive mode analysis. The method was validated for limit of qualification, linearity and inter-day variation of precision and accuracy. Seven T. wilfordii samples (extracts and commercial product) were successfully analysed.
