ABSTRACT
The extracts of Platycladus orientalis (L.) Franco leaves have shown promising anti-cancer, anti-oxidant and anti-inflammatory potency with the traditional knowledge of healing HPV associated warts. The purpose of this research is to assess the synergistic activity of sorafenib and Platycladus orientalis (L) leaf extraction on cervical cancer cells. The cytotoxicity efficiency of different concentrations of Sorafenib and ethanol extract of Platycladus orientalis (L.) leaves were tested on HeLa cells by MTT and Trypan blue assays. The synergistic effect of the IC50 concentrations of Sorafenib and Platycladus orientalis (L.) on HeLa cell by MTT assay, and mRNA expression levels of tumor suppressor tazarotene-induced gene 3 (TIG3), proliferating cell nuclear antigen (PCNA) gene and apoptosis modulator (Bcl-2) gene by RT-PCR were evaluated with individual treatments. Combination treatment showed a relatively more expression of TIG3 and less expression of Bcl-2 and PCNA was observed. Growth factor-induced MAPKP activation was arrested by compound combination treatment, which and suppression of proliferation-induced apoptosis of cervical cancer cells. Based on the our results, the combination of sorafenib and crude leaf extract from Platycladus orientalis (L.) can effectively suppress cervical cancer cell growth, thereby providing an interesting rationale for further clinical trials and in-vivo studies.

Objective To compare the tannin contents of Platycladus orientalis(L.) Franco and its carbonisatus.Method A tungsten molybdophosphate-casein colorimetric method was used with gallic acid as reference substance.Results The standard curve in the range of 0.026～0.26 mg(r =0.999 4),and the average recovery rate was 97.85%,RSD=1.07%(n =9).Conclusion The method is reliable and can be used to determine the tannic of and its different processed products.
ABSTRACT
Objective To establish an HPLC method for the determination of isopimaric acid in the leaves of Platycladus orientalis and its preparations Cebai No.V Capsula and Isopimaric Acid Capsula to evaluate the quality of them. Methods HPLC Method was developed. Kromasil C18(200 mm?4.6 mm, 5 ?m) column was used and the mobile phase: methyl alcohol-water-acetic acid (60∶37∶3), float rate: 1 mL/min, temperature: 25 ℃, wavelength: 231 nm, injected volume: 10 ?L. Content of isopimaric acid in samples was calculated by external standard. Results The linearity relationship of isopimaric acid was good in the range of 1.25-10.00 ?g. The equation of standard curve: Y=66 214 X+2 487.9, r=1.000. The average recovery was 95.8%, RSD=2.7% (n=5). The determination results of isopimaric acid in three batches of P. orientalis were 3.09, 3.20, and 3.56 mg/g; three batches of Cebai No.V Capsula were 10.39, 9.67, and 10.99 mg/g; three batches of Isopimaric Acid Capsula were 553.89, 541.50, and 528.83 mg/g. Conclusion The method is reliable, simple, and precise, which could be used for the quality control of P. orientalis and its capsules.
