A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.
METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.
RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).
CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.
