Objectives:To study the distribution, traditional knowledge, dose and preparations, phytoconstituents, pharmacognostic characters and to correlate phytoconstituents and the claimed health benefits among the tribal people of Arunachal Pradesh if any, the present study was carried out. Methods: Field survey and interview were used for ethnobotany and protocol given in Shah and Seth (2010), Kakote et. al.,(2012) and Wallis (2011) was followed to study pharmacognostic studies while GC-MS was used in the studies of phytoconstituents. Results: This study reports numbers of volatile and non-volatile compounds from the rhizome of Coptis teeta with high percentage of berberine alkaloids. The study also reports alkaloid deposition at parenchymatous tissues and vascular tissues of rhizome. Phytoconstituents presents in the ethanolic extract of C.teeta cold be related to health problems and phytoconstituents as claimed by tribal people of Arunachal Pradesh. Conclusion: Locally called Mishmi teeta in Arunachal Pradesh, Coptis teeta Wall. is a well-known medicinal plant used among Mishmi and other tribes of Arunachal Pradesh for health problems like loose motion, stomach pain, diarrhoea and malaria. This endemic and threatened medicinal plant contains numbers of biologically active compounds and need in-situ as well as ex-situ conservation.

Introduction: Mussaenda roxhburgii Hk.f. shoot is widely used as folk food among the tribal people of Arunachal Pradesh. This study was carried out to establish the phytoconstituents of Mussaenda roxburghii shoot. Methods: Fresh shoot were collected from Mone forest of East Siang district of Arunachal Pradesh and identified by the corresponding author himself. The samples were shade dried and pulverized to powder using a mechanical grinder. 500 g powder of the sample was soaked in ethanol for 72 hours with intermittent shaking then filtered through Whatmann No. 41 filter paper and concentrated under reduced pressure at 40°C by using rotary evaporator to obtain a viscous semi solid extract. Gas-Chromatography Mass Specrometry (GC-MS) analysis of the ethanol extracts was carried out in Shimadzu GCMS-QP-2010 plus system. The identification of compounds was performed by comparing their mass spectra with data from NIST 11 (National Institute of Standards and Technology, US) and WI-LEY 8. Results: The GCMS chromatogram of Mussaenda roxburghii shoot ethanolic extract gave forty nine phytochemical compounds. The most prevailing compounds were hydrocoumarin with 13.6%, hexadeconoic acid,

This study brings out the critical role of lesser-known local plant species in the food, nutrition and livelihood security of Adi community in Arunachal Pradesh, India. Considering women as a major custodian in knowledge and practices on foods, a total of 90 Adi women and 60 key knowledgeable community members (thus a total of 150 participants) were selected from East Siang and Upper Siang districts of Arunachal Pradesh. Data were collected using combination of methods including recipe contest, focus group discussion, personal interviews and laboratory analyses. The results indicated that Adi women were able to identify 39 bioculturally important species from a range of locally available plant species. Used alone or with other foods, these plants remain central to the Adi people's cultural identity and livelihood security. In addition to improving food and nutritional security, these species accessed from different land use systems, are also sold on the local markets to generate decent incomes. Of the species identified by Adi women, 28 were culturally shared and used frequently in food and ethnomedicine. Laboratory analyses of the selected 22 species revealed exceptionally high levels of minerals and other nutrients, such as proteins and anti-oxidants, supporting their traditional use for health benefits. Our study results provide valuable insights to the researchers to explore the vast hidden potential of these and other similar species for improving nutritional well-being of local communities in marginal areas. Adequate policy support is needed to enable Adi and other such marginalized communities to cope with challenges being posed to traditional food systems.

Crop diversity is a source of food, medicines, and fodder; it provides a proximate composition including carbohydrates, proteins, minerals, vitamins, fats, essential elements, and nutraceuticals for healthy growth and development of a body.  Jhum cultivation is a source of multiple crops and study on multiple sources of nutrients help in the dept understanding of diet and also framing of food policy; Present work was carried out to study the multiple cropping in Jhum agriculture field of the Upper Siang District of Arunachal Pradesh. To fulfill the objectives, field visit, open-end questionnaires and purposive samplings methods were used. A total of forty-three (43) crops were recorded to be cultivated in the Jhum field. Crops varieties of the study site could be classified into leafy vegetable crops, cereal crops, oil crops, pulses, spices crops, fruit crops, medicinal food plants, tuber crops and fiber crops.

Clerodendrum colebrookianumWalp.is a medicinal food plant widely used in the North East India. The herb is used as vegetable as well as medicine to control high blood pressure. Minerals and Proximate compositions in a food is vital for the proper growth and development of a healthy body and secondary metabolites included in diet act as a nutraceuticals thus help in fighting various health problems. The present study was carried out to discourse the Phytoconstituents, Proximate composition and Minerals of the nutraceutical herb, Clerodendrum colebrookianum. Methanol extract of sample was subjected to GCMS to profile the Phyoconstituents while Standard methods including AOAC was followed to study proximate and minerals of the sample under studied. Moisture content was 77.90%, carbohydrate 4.28%, 2.36% crude protein, 4.21% crude fibre and 0.35% crude fat respectively. The minerals concentrations are 0.215mg of Fe/g, 0.105mg/g of Mn, 0.0425mg of Cu/g, 0.056mg Zn/g, 2.55mg of Mangnesium/g, 4.3mg of Na/g and 24.5mg of K per gram of sample. A total of eleven compounds are recorded to be useful for high blood pressure problem and as many as other twenty useful phytoconstutuents were recorded from the sample including antioxidant, anti-uric acid formation, anti-tumour, bioabiability of zinc etc. The present study advocates the traditional knowledge on the use of Clerodendrum colebrookianum as a remedy for high blood pressure problem.
