Flavonoid Composition and Pharmacological Properties of Elaeis guineensis Jacq. Leaf Extracts: A Systematic Review

The oil palm tree (Elaeis guineensis Jacq.) originates from West and Central Africa, and it is cultivated in Malaysia for its oil-producing fruits. Malaysia is the world’s second largest palm oil producer and the world’s largest exporter to date. Consequently, the Malaysian oil palm industry constantly generates a huge amount of biomass with the major contributor being the leaves. A large percentage of these leaves remain underutilized, making them a promising source of raw materials that can be converted into value-added products. The present review summarizes and discusses the flavonoid composition, total phenolic and flavonoid content, and the in vitro and in vivo pharmacological properties exhibited by the extracts of the leaves of E. guineensis. The purpose of this systematic review is to highlight the potential of valorizing the leaf extracts of the oil palm tree as pharmaceutical and cosmeceutical agents.

African Oil Palm

Background: African oil palm (Elaeis guineensis Jacq.), a perennial crop that originated from Tropical rainforest of West Africa, is one of the most important economic oil crops in Nigeria providing income for rural and semi-urban folks. This study described the ethnobotany of the plant and evaluated the extent to which it contributes to the livelihood strategies of the Ikale and Ilaje speaking people of Ondo State, Nigeria. Methods: Interviews were conducted in the local language and questionnaires were administered to willing respondents. Photographs of tools/machines used in the production of palm oil and allied products were taken. Drawings of the tools were generated on site. Results: The plant is the principal source of palm oil. Major processing tools of palm oil include cracker, presser, digester, and boiling trough. Other products that are derived from oil palm parts are palm kernel oil, kernel meat (for livestock feed), kernel shells (for fuel), palm wine, broom, fish trap, and traditional soap. All these products are made using indigenous methods. They feature in medicinal preparations, traditional ceremonies and are important household commodities. Conclusions: The products derived from oil palm tree serve as means of livelihood in the study communities and are local resources used in everyday activities of the people. The indigenous production methods observed further emphasize the role these products play in the economy of oil palm product makers and sellers. Sustainable tapping of palm wine should be encouraged in order to derive maximum benefits from oil palm tree. Keywords: Ethnobotany, Economic Botany, African Oil Palm, Ondo State, Nigeria

AbstrakPenyakit busuk pangkal batang pada kelapa sawit (Elaeis guineensis Jacq.) disebabkan oleh Ganoderma boninense Pat. Bakteri selulolitik dari rizosfer kelapa sawit dapat dijadikan agen hayati dalam menghambat pertumbuhan G. boninense. Penelitian ini bertujuan untuk mendapatkan bakteri selulolitik dari rizosfer kelapa sawit dan menentukan efektivitasnya dalam menghambat pertumbuhan G. boninense. Tahap penelitian meliputi pengambilan sampel dari rizosfer kelapa sawit, isolasi, pemurnian, uji aktivitas selulolitik, dan uji daya hambat terhadap G. boninense serta identifikasi isolat bakteri yang potensial. Indeks selulolitik bakteri ditentukan dengan pewarnaan congo red 0,1%. Aktivitas penghambatan dilakukan dengan menentukan persentase daya hambat bakteri dalam menghambat G. boninense. Uji efektivitas dengan membandingkan hasil uji T pada taraf 5%. Hasil menunjukkan bahwa dari rizosfer kelapa sawit diperoleh 19 isolat bakteri selulolitik dengan indeks selulolitik tertinggi 4,38 pada isolat LBS1. Berdasarkan uji T dari efektivitas bakteri selulolitik terhadap G. boninense menunjukkan 6 isolat bakteri (LBS3, LBS4, DBS1, DBS7, SBS2 dan SBS6) memiliki nilai efektif atau berpotensi sebagai antagonis dengan persentase daya hambat tertinggi sebesar 40,17% isolat DBS1 yang merupakan genus Flavobacterium. Harapan kedepannya, bakteri selulolitik yang diperoleh dapat dijadikan agen biokontrol terhadap G. boninense.Abstract Basal stem root disease in oil palm tree (Elaeis guineensis Jacq.) is caused by Ganoderma boninense Pat. infection. Cellulolytic bacteria from rhizosphere can be used as agents to inhibit G. boninense growth as pathogenic fungi. Purpose of the research is to obtain cellulolytic bacteria from oil palm tree rhizosphere and to determine their effectiveness in inhibiting G. boninense growth. The research stages included sampling from the oil palm tree rhizosphere, isolation, purification, cellulolytic activity test and dual culture test against G. boninense and identification of effective isolates. The cellulolytic index of bacteria was determined by congo red 0.1%. Antagonistic test was conducted to determine persentation of isolate bacteria in inhibit G. boninense and effectiveness test by comparing result of T test at the level 5%. The results showed that there are 19 isolates of cellulolytic bacteria from oil palm tree rhizosphere with highest cellulolytic index 4.38 (isolates LBS1). Based on T test of the effectiveness cellulolytic bacteria against G. boninense showed 6 isolates (LBS3, LBS4, DBS1, DBS7, SBS2, and SBS6) had effective values or potential antagonists with highest percentage inhibition 40.17% isolate DBS1 genus of Flavobacterium. Hope that in the future, cellulolytic bacteria obtained can be used as biocontrol agents for G. boninense.
