Abstract

AbstrakPemanfaatan pucuk daun mangga (Mangifera indica L.) oleh masyarakat menjadi lalapan dan dipercaya berkhasiat sebagai obat tradisional. Hal ini merupakan suatu proses kearifan lokal berdasarkan pengalaman empiris orang-orang terdahulu yang kemudian dijadikan kajian studi ilmiah, yaitu etnobotani. Kajian studi etnobotani termasuk pemanfaatan pucuk daun mangga sebagai lalapan masih jarang dilakukan. Penelitian ini bertujuan untuk mengetahui senyawa bioaktif termasuk mangiferin yang terkandung dalam lima kultivar mangga. Sampel kultivar mangga yang digunakan dalam penelitian antara lain Manalagi, Arum manis, Cengkir, Gedong apel dan Golek. Metode penelitian yang digunakan yaitu skrining fitokimia dan pengukuran kadar senyawa mangiferin dengan HPLC. Hasil penelitian menunjukkan sampel positif mengandung senyawa bioaktif alkaloid, flavonoid, saponin dan tanin. Kadar senyawa mangiferin paling tinggi secara berurutan terdapat pada kultivar Arum manis (20,83%), Manalagi (20,56%), Gedong apel (18,54%), Cengkir (15,10%), dan Golek (5,05%). Kultivar mangga Arum manis memiliki kadar mangiferin paling tinggi, untuk selanjutnya dapat dikaji pemanfaatannya sebagai obat herbal tradisional. Abstract Utilization young leaf of mango (Mangifera indica L.) by the community as lalapan and it is believed to be efficacious as traditional medicines. This process through of local wisdom based on empirical experience of conservative people used as a scientific study, namely ethnobotany. Ethnobotany studies include the use of mango leaf shoots as fresh vegetables are still rarely performed.This study aims to determine bioactive compounds including mangiferin contained in five cultivars of mango. Mango cultivar samples used in this study include Manalagi, Arum manis, Cengkir, Gedong apel and Golek. The research method used was phytochemical screening and measurement of mangiferin compounds by HPLC. The results showed a positive sample containing bioactive compounds, alkaloids, flavonoids, saponins and tannins. The highest levels of mangiferin compounds were found in Arum manis (20.83%), Manalagi (20.56%), Gedong apel (18.54%), Cengkir (15.10%) and Golek (5.05%). Arum manis cultivars has highest value of mangiferin levels, which can be explored for their use as traditional herbal medicines.

Abstract

Sustained stress is risked for the emergence of various diseases including disability to depression. Clinically, antidepressant drugs are still the main option even though they are known have side effects for users. Therefore, various types of drug plants that have the potential as natural antidepressants have begun to be used, one of them is the young leaf of mango (Mangifera indica). It is known contains various bioactive compounds, including mangiferin which is useful as an antioxidant, anti-inflammatory, and plays a role in protecting nervous tissue. This study aimed to determine the effect of Mango’s young leaves extract of Arumanis cultivar as an antidepressant in zebrafish (Danio rerio) exposed to Unpredictable Chronic Stress (UCS). The method used is Completely Randomized Design (CRD) which consists of 3 treatments, namely K (Aquadest); P1 (extract concentration 10µg/mL); and P2 (extract concentration 20µg/mL). The parameters include the antioxidant activity and behavioral tests, namely new tank diving and light/dark preferences. The results showed that exposure to UCS tends to increased anxiety as indicated by a decrease in exploration on behavioral test. The data showed that the Mango’s young leaves extract induction with a concentration of 20µg/mL obtained the highest value percentage in the exploration of the upper area (36.8 s) and the preference of the bright area (90.8 s) significantly. The induction of mango’s young leaves extract has the potential as an antidepressant in zebrafish exposed to UCS with an optimal concentration of 20µg/ml.

Abstract

The Javan gibbon (Hylobates moloch) is one of the endemic primates that are protected on the island of Java. The results of research and surveys show that the Javan gibbon population in its natural habitat has a declining trend. Conservation efforts that can be done to rebuild the Javan gibbon population in the wild are by releasing them. For release, careful preparation and consideration is needed because the Javan gibbon has a high level of sensitivity to disturbance. This research was conducted at the Javan Primate Rehabilitation Center (JPRC) The Aspinall Foundation with the aim of knowing the release readiness status of the Javan gibbon pair based on 4 release criteria consisting of permanent partner readiness, daily activity readiness, health readiness and ability to consume natural food. The study was conducted on two pairs of Javan gibbons targeted for release, namely Udin-Lola and Joy-Bobby. Observations were made from January to February 2022 using the ad libitum method and scan sampling with an interval of 5 minutes . The results showed that based on 4 criteria for release, both partners were declared to have met the criteria for release, except for the status of the ability to consume natural food. During the observation, copulation activity was not observed, but the Udin-Lola pair was seen several times carrying out pre-copulation activities. Based on the value of readiness for release, the Udin-Lola pair were categorized as ready to be released into the wild with scores of 74.2. Meanwhile, the Joy-Bobby couple is not ready to be released with a score of 68.6.
