In vitro Penetration and in vivo Distribution of Honokiol into the Intervertebral Disc in Rat.
Honokiol is a potential candidate for the treatment of intervertebral disc (IVD) degeneration. In this study, we develop in vitro and in vivo methods to detect the distribution of honokiol in intervertebral discs using high-performance liquid chromatography. A rat tail disc was used for both experimental models. For the in vivo animal experiment, blood samples and tail discs were collected at 15, 30, 60, 120 and 240 min after honokiol administration (30 mg/kg, i.v.). The analyte was separated by a mobile phase of methanol and 10 mM NaH2PO4 buffer at pH 2.8 (78:22, v/v) and pumped through a reversed-phase analytical column (250 × 4.6 mm, particle size 5 μm) at room temperature. The in vitro experimental results demonstrated that honokiol diffused into the intervertebral disc and was concentration-dependent. The active concentration is obtained for the therapeutic level at 15 and 30 min after honokiol administration in the in vivo model.

[Study on the chemical constituent from the dichloromethane extract of the pine needle of Cedrus deodara (II)].
To study the chemical constituents of the dichloromethane extract from pine needles of Cedrus deodara.. The chemical constituents were isolated and purified from the dichloromethane extract of pine needles by chromatography on silica gel and Sephadex LH-20. Their structures were elucidated by analysis of spectral data and chemical properties.. Seven compounds were isolated and their chemical structures were identified as ferulic acid (1), osthole (2), beta-phenylacrylic acid (3), paeonol (4), beta-sitosterol (5), magnolol (6) and honokiol (7).. Compounds 1 - 4, 6 and 7 are isolated from this plant for the first time.

[Anti-tumor effect of tanshinone II A, tetrandrine, honokiol, curcumin, oridonin and paeonol on leukemia cell lines].
To study the anti-tumor effect of tanshinon II A, tetrandrine, honokiol, curcumin, oridonin and paeonol on leukemia cell lines SUP-B15, K562, CEM, HL-60 and NB4.. To study the anti-tumor effect of tanshinone II A, tetrandrine, honokiol, curcumin, The leukemia cell lines were exposed to the six Chinese herbal components for 96 hours. The proliferative inhibitory effects were detected with MTT and described by IC50 value.. Tanshinone II A inhibited the proliferations of SUP-B15, K562, CEM, HL-60 and NB4 cell lines, with HL-60 showing the least impact. Tetrandrine, honokiol, curcumin and oridonin inhibited the proliferations of SUP-B15, K562, CEM, HL-60 and NB4 cell lines and there was no significant difference between the cell lines. Paeonol did not have significant inhibitory effect on leukemia cell lines.. Tetrandrine, honokiol, curcumin and oridonin inhibit the proliferation of five cell lines SUP-B15, K562, CEM, HL-60, NB4, and the effects are similar, which means that their anticancer effects are quite broad. Tanshinone II A has better anti-leukemia effects on SUP-B15, K562, CEM, NB4 than on HL-60. The effect of paeonol against leukemia cell lines is poor.

Simultaneous determination of 12 chemical constituents in the traditional Chinese Medicinal Prescription Xiao-Yao-San-Jia-Wei by HPLC coupled with photodiode array detection.
An HPLC-photodiode array (PDA) detection method was established for the simultaneous determination of 12 components in Xiao-Yao-San-Jia-Wei (XYSJW): geniposide, puerarin, paeoniflorin, ferulic acid, liquiritin, hesperidin, naringin, paeonol, daidzein, glycyrrhizic acid, honokiol, and magnolol. These were separated in less than 70 min using a Waters Symmetry Shield RP 18 column with gradient elution using (A) acetonitrile, (B) water, and (C) acetic acid at a flow rate of 1 ml/min, and with a PDA detector. All calibration curves showed good linear regression (r(2)>0.9992) within the test ranges. The method was validated for specificity, accuracy, precision, and limits of detection. The proposed method enables in a single run the simultaneous identification and determination for quality control of 12 multi-structural components of XYSJW forming the basis of its therapeutic effect.
