The nature of the science of chemistry lends itself as a broad platform for improving the productivity of the Philippine economy through a technology-explicit development agenda. There is a wealth of knowledge and skills that chemistry can provide especially to enhance the national quality infrastructure like determining the composition of materials as they are processed through the supply and value chain, assessing the safety of various products in the market, monitoring the various elemental cycles in our environment, and discovering new materials and processes to promote national well-being. The role of chemistry can best be appreciated in facilitating trade, promoting economic efficiency, ensuring food security, enhancing environmental protection, responding to humanitarian emergencies, developing technologies for national defense and providing the scientific basis for policy formulation. At the very least Chemistry can identify leads to develop a niche for Philippine products that can compete in the global market.

Rafaelita M. Aldaba*, Phoebe Grace Saculsalan, and Jocelyn Mirabueno Department of Trade and Industry-Board of Investments Industry & Investments Bldg., 385 Se. Gil Puyat Avenue, 1200 Makati City, NCR Email of corresponding author: rafaelita.aldaba@gmail.com The Philippines is currently involved in eight (8) Free Trade Areas (FTAs) consisting of the ASEAN Free Trade Area (AFTA), ASEAN-China FTA (ACFTA), ASEAN–Korea FTA (AKFTA), ASEAN-Japan Comprehensive Economic Partnership (AJCEP), ASEANAustralia-New Zealand FTA (AANZFTA), ASEAN-India FTA (AIFTA), and the Philippines-Japan Economic Partnership Agreement or (PJEPA). Under these FTAs, the Philippines is expected to progressively reduce preferential tariffs toward zero tariffs on substantially all goods.

In this paper, the main objective is to analyze the extent and nature of participation of Philippine chemical firms in the ASEAN Economic Community (AEC) and other other (FTAs) signed by the country. Primary data is gathered through a firm-level survey to be conducted in the National Capital Region and nearby areas. The survey will collect information on the following firm characteristics: sales and exports, production and inputs, employment and human resource, technology and innovation, and government support.

The paper focuses on three major questions: what are the possible implications of the (AEC) and (FTAs) on the chemical sector? How are firms coping with the increased competition from imports arising from the AEC and other FTAs? Are firms actually participating in and availing of the benefits from FTAs? The paper evaluates how firms,especially SMEs, are adjusting to the new tariff environment and identify measures that firms have applied in order to improve their competitiveness and address the constraints that have prevented them from accessing ASEAN markets. This analysis is crucial in crafting appropriate policies and programs to help improve industry competitiveness and allow us to maximize the use of FTAs.

The Philippine Chemical Industry is the third largest sector of Manufacturing, contributing 6.7% of GDP worth about Php 330 Billion pesos per year revenues. The industry is comprised of Petrochemicals, Basic and Specialty Chemicals, Agrochemicals & Fertilizers, Industrial Gases, Oleochemicals & Surfactants, Coatings, Ink, Petroleum, Plastic and Rubber.

The Chemical Industry is one of the fastest growing sectors of the Philippine economy. In 2013, it grew by 18% Gross Value Added. The 5-year average (2006 -2010) growth is 7% and 17% for Chemical Manufacturing and Chemical Exports, respectively. In the roadmap submitted by SPIK, the industry is targeting a doubling of export to US$ 5 Billion by 2016 and US$ 10 Billion by 2022.

With the integration of the ASEAN Economic Community (AEC), the Chemical Industry does not expect a drastic reduction of trade since the zero tariff duties for 99.65% of products have been in place since 2010. The challenge to the industry, however, may be the brain drain of technical manpower of the local chemical manufacturing due to the projected free flow of workers in the AEC regime.

The Chemical Industry is expected to surmount and even excel in the AEC integration due to the strength the industry possesses such as: (1) manufacturing competence in terms of facilities, processes and manpower (2) marketing and logistics skills (3) strong compliance with environmental, safety, health and security regulations (Responsible Care®) (4) partnership with the government, academe and related industries.

The opportunities that may open up to the industry are: (1) emerging market specially for coco-based products (oleochemical and activated carbon) (2) shift in consumer preferences for natural products, health and wellness product (3) strong Philippine economy.

And the challenges, aside from the possible brain drain, are: (1) smuggling and dumping (2) enforcement of unscientific (not science-based) regulations.

Weighing all the above possibilities, the Chemical Industry is still expected to grow and attain the objectives it sets in the Chemical Masterplan despite the perceived threat ascribed to the AEC integration.

The capacity of any country or region to exploit the benefits of international trade relies extensively in their capacity to show credible compliance with legislative and market requirements. While national products may meet good quality standards in the domestic market, a significant part of the manufacturers or service providers’ credibility is linked to the long standing relationship with their clients and communities and recognizable local practices. However, when reaching out for external markets, as the neighboring ASEAN countries, credibility and proof of quality does not rely exclusively on the provider-client relationship, but on a coordinated, shared and internationally recognized system that is called the Quality Infrastructure. It is the capacity at national level to implement a National Quality Infrastructure strategy what leads to more competitive domestic industry with greater market access. The National Quality Infrastructure strategy is a pillar for exploiting the benefits of the economic regional integration in the ASEAN Community. However, National Quality Infrastructure does not belong to one single institution, either public or private, not a single piece of legislation can secure its implementation, not one actor can independently design or develop such an strategy. The systemic nature of the National Quality Infrastructure and its integration in a wider international system, requires a sustained coordination effort and a collective belief of the benefits of implementing international practices and recognized mechanism of showing compliance.

The internet provides a wealth of information related to food, but the accuracy of the information provided may be tainted by advocacy, politics, religious and cultural biases, economic gain or inherent penchant for misinformation. With its wide accessibility, the internet-using public is bombarded with a plethora of information whose veracity needs to be evaluated. This paper shows some examples of misleading information culled from various websites, and provide counterpart information obtained from more reliable internet sources.

We also offer some guidance on discerning which internet sources are reliable and put forward some advice on how to check the reliability of information gleaned from various websites.

The objective of the ASEAN integration is to promote regional growth in sectors where ASEAN has a clear competitive advantage. Healthcare emerged as one of ASEAN’s priority sectors and regulatory harmonization has dominated the conversations to eliminate technical and trade barriers for pharmaceutical manufacturing and sales. Understandably, the upstream process of drug development is less discussed but remains crucial to manufacturability and applicability (quality, safety, efficacy). A culture change in how we view drug development is critical for the Philippines to have a competitive share of the pie; to be a major active contributor not just a passive market consumer. Our biodiversity promises a treasure trove of multiple healthcare applications. We foster a productive debate that strives to engage various stakeholders, from our farmers and manufacturers to our regulators and scientists, in taking a systems approach to natural-product-based drug development.

This study was conducted to evaluate the possible anthelmintic activities of the decoction and the nonpolar constituents of the aerial parts of the endemic plant Cyperus brevifolius Rottb. against Eudrilus eugeniae or African nightcrawler earthworms. The in vitro anthelmintic assay was done by determining mean time of paralysis and death of the earthworms at three concentrations (3, 25, and 50 mg/mL). Results showed hexane-soluble extract (CBH) exhibited better anthelmintic activity in terms of mean time of paralysis than the decoction (CBD) at 25-mg/mL concentration (16.35±4.30 min and 180 min, respectively) as well as at the 50-mg/mL concentration (13.50±3.86 min and 19.19±3.90 min, respectively). This is validated by the result obtained with respect to the mean time of death of test organism at 25-mg/mL concentration (62.62±5.90 min for CBH and 180 for CBD) and at 50-mg/mL concentration (31.63±5.87 min for CBH and 37.99±5.27 min for CBD).

And, among the fractions obtained from CBH, only CBH4 showed a notable activity as exhibited by faster mean time of paralysis and death of the test organisms compared to its mother solution, CBH. Moreover, CBH4 showed a comparable anthelmintic activity with the positive control mebendazole at 3-mg/mL concentration. Therefore, C. brevifolius exhibited anthelmintic activity specifically its nonpolar components, the CBH and it fraction CBH4.

The objective of this study is to evaluate the antidiabetic potential of curcumin by investigating its antioxidant activity and -glucosidase inhibitory activity. Curcumin is a natural compound found in luyang dilaw (Curcuma longa) and Indian spice turmeric. Several studies have already reported its antioxidant, anti-inflammatory, antiviral and antifungal actions. There are also reports demonstrating its anti-cancer action because it can act as a powerful antioxidant and as an inhibitor of cancer cell growth.

Diabetes mellitus is associated with an increased production of free radicals and also with a decrease in the antioxidant potential leading to oxidative stress. The antioxidant property of curcumin was determined using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. In this method, DPPH, a purple-colored stable free radical is reduced into the yellow-colored diphenylpicryl hydrazine in the presence of an antioxidant. The color intensity of the reaction was measured using a Microplate reader set at 510 nm.
