There is an ongoing interest to identify alternative pesticidal agents to avoid the chronic problems associated with synthetic pesticides. Essential oils have shown promise as botanical pest control agents. In the present study, the essential oils of four members of the Lamiaceae (Callicarpa candicans, C. erioclona, C. macrophylla, and Karomia fragrans; Vietnamese names: Nàng nàng, Tu châu lông mem, Tu châu lá to and Cà diện, respectively), obtained from wild populations in Vietnam, have been obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The essential oils were formulated into microemulsions and the essential oils and their microemulsions were screened for mosquito larvicidal activity against Aedes aegypti, Aedes albopictus, Culex quinquefasciatus, and for molluscicidal activity against Pomacea canaliculata. Atractylone and (E)-caryophyllene dominated the volatiles of C. candicans (CCEO) and C. erioclona (CEEO), while the major component in C. macrophylla (CMEO) and K. fragrans (KFEO) was (E)-caryophyllene. The essential oils and microemulsions of both C. candicans and C. erioclona exhibited excellent larvicidal activity against all three mosquito species (Ae. aegypti, Ae. albopictus, and Cx. quinquefasciatus) with LC 50 values < 10 μg/mL. Additionally, the larvicidal activity of the microemulsions were significantly improved compared with their free essential oils, especially for C. candicans and C. erioclona. All four essential oils and their microemulsions showed excellent molluscicidal activity with LC 50 < 10 μg/mL. In most cases, the essential oils and microemulsions showed greater pesticidal activity against target organisms than the non-target freshwater fish, Oreochromis niloticus. The in silico studies on physicochemical and ADMET properties of the major components in the studied essential oils were also investigated and most of the compounds possessed a favorable ADMET profile. Computational modeling studies of the studied compounds demonstrated a favorable binding interaction with the mosquito odorantbinding protein target and support atractylone, β-selinene, and caryophyllene oxide as potential inhibitors. Based on the observed pesticidal activities of the essential oils and their microemulsions, the Callicarpa species Supporting information for this article is available on the WWW under

Scutellaria L. is a genus of flowering plant in the Lamiaceace. The genus includes about 350 species commonly known as skullcaps. Scutellaria is widespread in temperate regions and tropical mountains including Europe, North America and East Asia. 15 species belonging to Scutellaria genus were recorded in Vietnam. The perennial herb Scutellaria tonkinensis Doan is an endemic species of Vietnam and is recorded in Lao Cai and Vinh Phuc provinces. In this study, anatomical charateristics of this species using double-staining method have been investigated. The anatomical characteristics indicate that S. tonkinensis Doan adapt to a habitat with high moisture and intensive insolation.

“…The plant is a shrub or small tree (Figure 1), 6 -8 m in height and is distributed in Pakistan, Nepal, Bhutan, India, Sri Lanka, Bangladesh, Myanmar, China, Thailand, Laos, Cambodia, Viet Nam, Peninsular Malaysia, Singapore, Sumatra, the Philippines, Sulawesi, and New Guinea [2,3]. In Viet Nam, the plant has been recorded from Lao Cai, Cao Bang, Bac Kan, Vinh Phuc, Ha Noi, Hoa Binh, Hai Duong, Ninh Binh, Thanh Hoa, Nghe An, Kon Tum, and Ba Ria-Vung Tau provinces [4,5]. In Chinese traditional medicine (TCM), a powder of C. arborea leaves is used externally to stop traumatic bleeding [6].…”

The essential oil from the leaves of Callicarpa arborea Roxb. growing wild in Vietnam, was obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry. The major constituents of leaves of C. arborea were β-selinene (23.9%), ar-turmerone (17.5%) and α-copaene (8.9%), with lesser concentrations of caryophyllene oxide (4.9%) and ar-turmerol (3.9%). The chemical composition of this essential oil sample is being reported for the first time.
