5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solids Classification not possible - - - - No data available.
8 Self-reactive substances and mixtures Classification not possible - - - - It contains chemical groups associated with self-reactive properties (C=C) and does not contain chemical groups associated with explosive properties. Since no further information is available, classification is not possible.

11 Self-heating substances and mixtures Classification not possible - - - - No data available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Not applicable - - - - The substance contains oxygen (but not fluorine or chlorine) which is chemically bonded only to carbon or hydrogen.
15 Organic peroxides Not applicable - - - - Organic compounds containing no bivalent -O-O- structure
16 Corrosive to metals Classification not possible - - - - No data available.

HEALTH HAZARDS

1 Acute toxicity （Oral） Category 3 Danger H301: Toxic if swallowed P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P321: Specific treatment （see ... on this label）.
P330: Rinse mouth.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Since its rat LD50 = 110 mg/kg (RTECS, accessed in September 2007), the substance was classified into Category 3.
1 Acute toxicity （Dermal） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Since the substance is a solid (GHS definition), it was classified into the "Not applicable" category.
1 Acute toxicity （Inhalation: Vapours） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Dusts and mists） Classification not possible - - - - No data available.
2 Skin corrosion/irritation Classification not possible - - - - No data available.
3 Serious eye damage/eye irritation Classification not possible - - - - No data available.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - No data available.
5 Germ cell mutagenicity Category 2 Warning H341: Suspected of causing genetic defects P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Ames tests, in vitro chromosomal aberration tests using mammalian cells, and gene mutation tests gave positive results. In addition, micronucleus tests using fetal mice also produced positive results although it was carried out using unconventional methods (IARC 10, 1976; EHC 80, 1988; NTP DB, accessed in September 2007). Based on these results, the substance was classified into Category 2.
6 Carcinogenicity Category 2 Warning H351: Suspected of causing cancer P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Since the substance is rated as Group 2B by IARC S7 (1987), it was classified into Category 2.
7 Reproductive toxicity Classification not possible - - - - Classification not possible due to lack of data. EHC 80 (1988) reported that in rats received 35mg/kg bw of lasiocarpine through intraperitoneal administration on days 13 and 17 of pregnancy, necrosis was seen in the fetal liver but not in that of the mother. However, since the experimental design used was unconventional, we did not use this study for classification.
8 Specific target organ toxicity - Single exposure Category 1 (liver, blood system) Danger H370: Causes damage to organs (liver, blood system) P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P321: Specific treatment （see ... on this label）.
P405: Store locked up.
P501: Dispose of contents/container to ... 		In animal tests, weanling rats were given a single dose of lasiocarpine at 120 mg/kg bw, and up to 18 days after administration, no hepatic lesions were found by autopsy; between 19 and 123 days, delayed hepatic lesions were found by autopsy in 34/49 rats and these 34 rats also showed megalocytosis (EHC 80, 1988). Based on these reports, we concluded that the liver and blood system are target organs of lasiocarpine. The effects of the substance on test animals were seen at doses that fall under the range of Category 1 guidance values. Thus, the substance was classified into Category 1 for the liver and blood system.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - No data available.
