Reciprocal actions of acupoints on gastrointestinal peristalsis during electroacupuncture in mice.

Orthogonal design was used to observe the gastrointestinal peristalsis in normal and atropine-treated mice after electroacupuncture was applied, singly or in combination, at Neiguan (P 6), Pishu (UB 20) and Zusanli (St 36). The results showed that: 1) electroacupuncture has no significant effect on the gastrointestinal peristalsis in normal mice; 2) Pishu (UB 20) was significantly antagonistic to Zusanli (St 36) in normal mice; 3) the decreased gastrointestinal peristalsis in atropine-treated mice was markedly promoted by electroacupuncture at Zusanli (St 36); and 4) Neiguan (P 6) was significantly antagonistic to Pishu (UB 20) in atropine-treated mice. The results indicated that the reciprocal actions among acupoints should be taken into consideration for point prescription.

[Analysis of cinnamic acid in storax and its original plant by HPLC].

The contents of free and hydrolytic cinnamic acid in storax and its original plant (Liquidambar orientalis) were determined by high performance liquid chromatography, and the chromatographic behaviors were studied. In styrax gummi, the contents of free and hydrolytic cinnamic acid were 7.03% and 25.

Cyclocariosides II and III: two secodammarane triterpenoid saponins from Cyclocarya paliurus.

Two new secodammarane triterpenoid saponins were isolated from the leaves of Cyclocarya paliurus. Based on chemical and spectral analysis they were assigned as (20S)-20-hydroxy-24-O-alpha-L-arabino-pyranosyl-3,4- secodammar-4(28),11,25-trien-3-oic acid, named cyclocarioside II and 25-hydroxy-(20S,24R)-epoxy-12R-O-beta-D- quinovopyranosyl-3,4-secodammar-4(28)-en,3-oic acid, named cyclocarioside III.

[Active antisenile constituents in Cistanche deserticola Y. C. Ma].

From the dry bulbs of Cistanche deserticola a branch of orobahchacease plant growing in Inner Mongolia two active antisenile constituents (D-mannitol and polysaccharide) were isolated and identified. Chemical analysis and spectroscopic tests show that D-mannitol corresponds to the authentic standard, and polysaccharide is condensed from rhamnose, xylose, arabinose and galactose.

[Chemical constituents of Cyclocarya paliurus (Batal.) Iljinsk].

Four compounds were isolated from the leaves of Cyclocarya paliurus. They were identified as daucosstero, beta-L-arabopyranose, steraric acid and palmitic acid on the basis of spectral data and chemical properties. All of them were isolated from this plant for the first time.

[Drug identification and research on Fritillaria monantha Migo (pengze beimu) produced in Jiangxi Province].

This paper reports the drug identification and investigation on plant of Fritillaria monantha(Pengze Beimu) produced in Jiangxi Province. It has been found that F. monantha is a new distribution of genus Fritillaria in Jiangxi and a new variety of Chinese drug of beimu.

[Pharmacological studies on dingchuanning].

Dingchuanning has been found to increase markedly the perfusion of isolated lung of guinea-pig. It may produce a relaxing effect on the smooth muscles of the isolated trachea, bronchus and lung strips of guinea-pigs, as well as a prominent protective effect on the bronchial asthma induced by inhalation of bronchoconstrictors in conscious guinea-pigs. It also has significant expectorant and antianaphylactic effects and helps to inhibit markedly the SRS-A release from lung tissues and to counteract directly the activity of SRS-A.
