ABSTRACT
Opium poppy, coca and cannabis are raw materials for three notorious illicit drugs. For a long time, drug lords have been growing and smuggling these drugs in a variety of ways and channels and are continually finding new ways of trafficking their wares, which has led to the increasing difficulty of global drug enforcement. In the present paper, we propose an innovative pollen identification system for these important drug plants, which provides a tool for screening and detection of the drugs to aid in drug enforcement. By utilizing the characteristics of these fine particles, their abundant production, and high resistance to decay, we believe this tool could be applied in the following scenarios: detecting and dynamically monitoring drug cultivation activities; determining whether a suspect has been to fields of drug plants and determining whether the site has ever been planted with a drug plant and/or was involved in drug production. In the future, combined with microscope automatic image acquisition technology and intelligent image recognition technology, this pollen identification system is expected to be used to screen three notorious illicit drug plants, thus enhancing the efficiency of drug related crime investigations.
ABSTRACT
RESUMO Boldo-do-chile (Peumus boldus) e camomila (Matricaria recutita) são plantas empregadas na fitoterapia principalmente para o tratamento de desordens hepáticas e intestinais, atuando também como anti-inflamatório e antiespasmódico, respectivamente. Por isso, o presente trabalho objetivou avaliar a qualidade farmacognostica dessas drogas vegetais comercializadas em Fortaleza (CE), além das informações de suas rotulagens. Quarenta e duas amostras de boldo, e quarenta e cinco amostras de camomila, procedentes de farmácias, de lojas de produtos naturais e de bancas de raizeiros, foram analisadas quanto à autenticidade, à pureza e às informações contidas na rotulagem desses produtos conforme legislação vigente. Na verificação de impurezas, 35,7% das amostras de boldo e 57,7% das amostras de camomila excederam o teor máximo de matéria estranha; no teor de cinzas totais, 33,3% das amostras de boldo foram reprovadas; rotulagens das amostras de boldo (100%) e de camomila (96,6%) apresentaram erros ou ausência de informações. Os resultados das análises confirmam, portanto, a necessidade urgente de melhor fiscalização e intervenção na produção e venda dessas e de outras drogas vegetais para adequação às normas vigentes.
ABSTRACT Boldo (Peumus boldus) and chamomile (Matricaria recutita) plants are mainly used in herbal medicine to treat hepatic and gastrointestinal diseases, having also anti-inflammatory and antispasmodic properties. This study aimed to evaluate the pharmacognostic quality of these herbal drugs sold in Fortaleza (CE), besides analyzing the information on their labeling. Forty-two samples of boldo, and forty-five samples of chamomile, brought from pharmacies, health food stores and newsstands were analyzed regarding their authenticity, purity, and the information contained in the labeling of the industrial products, to assure that it was in accordance with the current legislation. When verifying the impurities, 35.7% of the boldo samples and 57.7% of the chamomile ones exceeded the maximum level of strange organic matter allowed. Concerning the total ash content, 33.3% of boldo samples were rejected. The labels on the packages of boldo (100%) and chamomile (96,6%) contain errors or lack of information. The test results confirm the need for better surveillance and intervention in the production and sale of these and other drugs plants in order to meet the current standards.
