Resveratrol suppresses human cervical carcinoma cell proliferation and elevates apoptosis via the mitochondrial and p53 signaling pathways.

Numerous studies have demonstrated the apoptotic and anti-proliferative effects of resveratrol, a natural polyphenolic phytoalexin, on various cancer cell lines. However, the effects of resveratrol on the regulation of human cervical carcinoma, and the mechanisms underlying these effects, remain to be elucidated. In the present study, the potential mechanisms underlying the effects of resveratrol in HeLa cervical carcinoma cells were investigated.

[Macroscopic and Microscopic Identification of Ganoderma and The Confusable Medicinal Mushrooms of "Zhi"].

Objective: To compare the macroscopic and microscopic characteristics of Ganoderma and the confusable medicinal mushrooms of "Zhi".

Methods: The methods of macroscopic and microscopic examination were employed to authenticate Ganoderma and the other medicinal mushrooms of "Zhi" in the fungal group.

Results: The medicinal mushroom named "Zhi" could be distinguished from each other by the shape of pileus, stipe and the characteristics of mycelium and spore.

[Study on HPLC-DAD Fingerprint of Xiaoying Jiedu Decoction].

Objective: Based on backtracking method, identification and quality evaluation of Xiaoying Jiedu Decoction (XYJDD) by HPLC fingerprint analysis were carried out.

Methods: HPLC-DAD fingerprint of XYJDD was conducted with Dikma Platisil ODS C18 column (250 mm x 4.6 mm, 5 µm) and gradient elution with the mobile phase consisting of acetonitrile-(0.

[Chemical constituents of Juncus setchuensis].

Objective: To study the chemical constituents of Juncus setchuensis.

Methods: Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data.

[Study on the chemical constituents of Psoralea corylifolia].

Objective: To study the chemical constituents of Psoralea corylifolia.

Methods: Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data.

[Determination of baicalin in Xiaoyanling Decoction by high-performance liquid chromatography].

Objective: To establish a high-performance liquid chromatography (HPLC) method for the determination of baicalin in Xiaoyanling Decoction.

Methods: HPLC method was used for determination. A Kromosil C18 column was used.

[Effect of ultra-fine powder technique on dissolution rates of andrographolide and dehydroandrographolide in Andrographis paniculata].

Objective: To investigate the effects of ultra-fine powder technique on dissolution rates of the components in Andrographis paniculata.

Methods: High performance liquid chromatography was employed to determine the concentration of andrographolide and dehydroandrographolide in common powdered or ultra-fine powdered Andrographis paniculata.

Results: The dissolution rates of andrographolide and dehydroandrographolide in ultra-fine powdered Andrographis paniculata were higher than those of the general powder.
