The phytochemical research on the leaves of led to the isolation and identification of two new hexenol glycosides, two new butenol glycosides, and five new sugar esters, named ligurobustosides X (), X (), Y (), and Y () and ligurobustates A (), B (), C (), D (), and E (), along with seven known compounds ( and -). Compounds - were tested for their inhibitory effects on fatty acid synthase (FAS), α-glucosidase, and α-amylase, as well as their antioxidant activities.

Phenylethanoid and Phenylmethanoid Glycosides from the Leaves of and Their Bioactivities.

The phytochemical study on the leaves of , which have been used as Ku-Ding-Cha, led to the isolation and identification of three new phenylethanoid glycosides and three new phenylmethanoid glycosides, named ligurobustosides R (), R (), R (), S (), S (), and S (), and five reported phenylethanoid glycosides (-). In the bioactivity test, ()-osmanthuside B () displayed strong fatty acid synthase (FAS) inhibitory activity (IC: 4.55 ± 0.

Monoterpenoid Glycosides from the Leaves of and Their Bioactivities.

The leaves of have been applied as Ku-Ding-Cha, a functional tea to clear heat, remove toxins, and treat obesity and diabetes, in Southwest China. The phytochemical research on the leaves of led to the isolation and identification of eight new monoterpenoid glycosides (-) and three known monoterpenoid glycosides (-). Compounds - were tested for the inhibitory activities on fatty acid synthase (FAS), -glucosidase, -amylase, and the antioxidant effects.

Study on the Salivary Microbial Alteration of Men With Head and Neck Cancer and Its Relationship With Symptoms in Southwest China.

This study explored the association between oral microbes and head and neck cancer (HNC) as well as symptoms related to patients with HNC before surgical treatment. Fifty-six patients with HNC and 64 matched healthy controls were recruited from West China hospital in Southwest China. The demographic, clinical, and symptom data were collected.

[Identification of the Strain Which Highly Produces Protease and β-D-glucosidase Isolated from Shuidouchi Produced in Sichuan and Evaluating Its Ability of Producing Protease].

Objective: To select and identify the bacterium which highly produces protease and β-D-glucosidase from 72 strains of Shuidouchi from Sichuan, and to provide evidence for further research on its nutritional value and fermentation strain exploiting.

Methods: Casein degradation test and pNPG chemical test were applied respectively to detect the capacity to produce protease and β-D-glucosidase of each strain. Characteristics of morphology, biochemistry, 16S rRNA and MALDI-TOF-MS were used to identify the fermentation strain, which genetic stability, curves of growth and enzyme producing were also obtained.

Molecular characterization of enterovirus 71 sibling strains for thermal adaption in Vero cells with adaptive laboratory evolution.

Enterovirus 71 is the main pathogen that causes severe and fatal hand-foot-mouth-disease (HFMD) cases. As the enterovirus virus mutation has implications for pathogenesis, vaccine development, antiviral therapy, and epidemiological disease management of the virus. In this study, we investigated the variations of enterovirus 71 in thermal adaption, using the method of adaptive laboratory evolution.
