  • In order to estimate accurate quality of crude drugs in which pest was found during the storage, damaged 15 items were collected on current markets. We identified insect name by investigation of insect morphology, bug cluster, and morphology of damaged crude drugs. Three kind of pests were identified in the above 15 items as follows: A: Pyralis sp. (Pyralidae) was observed in damaged Platycodi Radix. B: Anthreus verbasci (Anobiidae) was found out in damaged Angelicae gigantis Radix, and Dioscoreae Rhizoma. C: Stegobium pamceum (Anobiidae) was discovered in the 12 crude drugs as follows: Puerariae Radix, Angelicae koreanae Radix, Angehcae tenuissimae Radix, Codonopsis Radix, Ledebouriellae Radix, Ginseng Radix alba, Angelicae dahuricae Radix, Belamcandae Rhizoma, Paeoniae Radix, Cnidii Rhizoma, Alismatis Rhizoma, and Fritillariae Bulbus.

  • The cytotoxicity of crude insect drugs was measured using HeLa cells originating from human cervix and uterine cancer. using the dye uptake assay in order to find potential anticancer agents. Three kinds of extracts (buffer, methanol and ethylacetate) were prepared from 26 insects and used as raw materials for the activity assay. Among these, the buffer extracts from Tabanus, Mylabris and Huechys showed a potent anticancer activity, and those from Catharsius, Red ant, Scorpion, Tabanus and Vespae Nidus showed a strong L-amino acid oxidase (AAO) activity as well as cytotoxicity. In contrast, buffer extracts from Gryllotalpa orientalis and Apriona germari larvae showed greater/more rapid Hela cell growth than that of other insects.

  • The in vitro anticoagulant and fibrinolytic activities of crude extracts from insects were evaluated in order to find effective therapeutic drugs for the treatment of myocardial and cerebral thrombosis. We prepared three types of extracts (water, methanol and ethylacetate) from 28 insects for use as raw materials for the activity assays. The fibrinolytic activity was tested using the fibrin plate method and the activated partial thromboplastin time and thrombin time were measured for blood clotting activity. With regards to the fibrinolytic system, water extracts of six kinds of insects displayed a remarkable level of activity with a plasmin-like action. The water extracts of [Catharsius molossus, Eupolyphaga sinensis, Huechys sanguinea, Mantidis $o\ddot{o}theca$, Mimela splendens, and Polistes mandarinus (Vespae Nidus)] exhibited the activity. On the other hand, the methanol extracts did not display any fibrinolytic activity. In terms of the coagulation system, an aqueous extract of silkworm Tongchunghacho (Paecilomyces japonica), Oxya japonica japonica and Buthus martensi (Scorpion) increased the clotting time significantly longer (181 times) than the control. These results suggest that crude drugs from insects are useful sources for the development of new drugs for use in treatments involving blood coagulation and fibrinolysis.

  • The cricket has been used in East Asia as crude drugs for treating fever and hypertension, and is presently reared as a pharmaceutical insect in China and a food for animals. For the purpose of evaluating protective extracts against alcohol-induced toxicity, the extracts of the cricket (Gryllus bimaculatus) were examined in animal models acutely administered alcohol by the cricket in ICR-mice. Water and methanol extracts from the cricket, were found to cause a significant decrease (37%) in the blood ethanol concentration as well as enhancement of liver mitochondrial alcohol dehydogenase (ADH) and acetaldehyde dehydogenase (ALDH) activitieson on a single intraperitoneal administration in mice. Futhermore methanol extract was demonstrated to exhibit more potent enhancing activity on ethanol metabolism than water extract. These results suggest that water/alcohol extract of G. bimaculatus may be used as a food for reducing the toxicity of alcohol.
