RESUMEN
OBJECTIVE: To study chemical composition of n-butanol fraction from Polygonoum amplexicaule var. sinense. METHODS: TLC,normal-phase silica gel, reveres-phase silica gel, Sephadex-LH and semi-preparative HPLC were used to isolate chemical compositions of n-butanol fraction from Polygonoum amplexicaule var. sinense. RESULTS: Nine compounds were identified as: caffeic acid n-butly ester (1), p-methoxy benzoic acid propyl ester (2),p-E-coumarin quinic acid methyl ester (3),p-Z-coumarin quinic acid methyl ester (4), ethyl ferulate (5), cinchonain I a (6), cinchonain Ib (7), methyl chlorogenate(8), and 6-O-ß-D-caffeoylglucose (9). CONCLUSION: All compounds are isolated from this genus for the first time.

Compound Wuzhigan capsules is a compound preparation composed of Wuzhigan, Shidagonglao, Gangmei, Shanzhima. A Randomized, double-blind, multi-center, positive parallel control designed to evaluate the clinical efficacy and safety of compound Wuzhigan capsules on anemopyretic cold. One hundred and twenty anemopyretic cold patients were given compound Wuzhigan capsules (test group), 2 capsules one time, three times a day, 119 patients were given compound Wuzhigan tablets (control group) ,4 tablets one time, three times a day; three days of treatment The study showed, the markedly effective rate and total effective rate respectively were 63. 3% and 80% of the test group. For the control group, the markedly effective rate and total effective rate respectively were 72. 5% and 80. 7%. The difference was not statistically significant. Compound Wuzhigan capsules can reduce the dosage, and get better patient compliance.

OBJECTIVE: To study chemical composition of ethylacetate fraction from Polygonoum amplexicaule D. Don var. sinense Forb. METHODS: TLC, Normal-phase silica gel column, reveres-phase silica gel column, Sephadex-LH, semi-preparative HPLC column were used to isolate chemical compositions of ethylacetate fraction from Polygonoum var. sinense. RESULTS: Eight compounds were identified as: 1. P-Hydroxybenzoic acid, 2. P-Hydroxybenzoic ethanol, 3. Diisobutyl phthalate, 4. Vanillin, 5. Isovanillic acid, 6.3,4,5-trihydroxy-benzoic acid-butyl ester, 7. 4-hydroxy-3-methoxycinnamic acid, 8. 7-hydroxy-6-methoxycoumarin. CONCLUSION: Except of Diisobutyl phthalate, the others are isolated for the first from this plant, moreover, Vanillin, Isovanillic acid and P-hydro -xyphenethyl alcohol are gained from genus for the first time.
