“…The part used for agarwood tea was obtained from young leaves of Aquilaria spp. Therefore, our result supports that young leaves of agarwood is suitable for herbal tea preparation due to high level of IP3G compare to other stage of leaves (Kamonwannasit and others ). In addition, the application of the developed ELISA for IP3G content in herbal tea was investigated.…”

Polyclonal antibody against iriflophenone 3-C-β-d-glucoside (IP3G), a major compound from the leaves of Aquilaria spp., was produced for the development of an enzyme-linked immunosorbent assay (ELISA). The results showed that the antibodies were specific for IP3G. The produced antibody has low cross reactivity with iriflophenone 3,5-C-β-d-diglucopyranoside (13%), genkwanin 5-O-β-primeveroside (3.55%) and no cross reactivity found in other compounds. The range of ELISA assay extends from 100 to 1560 ng/mL with coefficient of variation (CV) 1.19% to 2.07% for intra-assay and 3.76% to 7.15% for inter-assay precision levels. The recovery rates of IP3G in the leaves of Aquilaria spp. were in the range of 96.0% to 99.0% with CV 4.50% to 5.32%. A correlation between ELISA and high-performance liquid chromatography methods was obtained when analysis of IP3G in the plant samples (R(2) = 0.9321). These results suggest that the developed ELISA method can be applied to determine IP3G content with high specificity, rapidity, and simplicity. The developed immunosorbent assay in this study provides a useful tool for the analysis of IP3G in plant samples and products.

Xao tam phan (Paramignya trimera (Oliv.) Guillaum) has been used as a medicinal plant for cancer prevention and treatment in recent years. The objective of this study was to determine the physicochemical, antioxidant, and cytotoxic properties of crude P. trimera root (PTR) extract and its fractions using MeOH as a solvent and microwave-assisted extraction as an advanced technique for preparation of the PTR extract. The results showed that the PTR extract had high contents of saponins, phenolics, flavonoids, and proanthocyanidins (7731.05 mg escin equiv. (EE), 238.13 mg gallic acid equiv. (GAE), 81.49 mg rutin equiv., and 58.08 mg catechin equiv. (CE)/g dried extract, resp.). Antioxidant activity of PTR extract was significantly higher (P < 0.05) than those of four its fractions and ostruthin, a key bioactive compound in the P. trimera, while potent cytotoxic capacity of PTR extract on various cancer cell lines in terms of MiaPaCa-2 (pancreas), HT29 (colon), A2780 (ovarian), H460 (lung), A431 (skin), Du145 (prostate), BE2-C (neuroblastoma), MCF-7 (breast), MCF-10A (normal breast), and U87, SJ-G2, SMA (glioblastoma) was observed with GI values ranging from 15 to 32 μg/ml. Cytotoxic potential on pancreatic cancer cells of PTR extract (100 - 200 μg/ml) was significantly higher (P < 0.05) than those of its four fractions (50 μg/ml), ostruthin (20 μg/ml) and gemcitabine (50 nm), and being comparable to a saponin-enriched extract from quillajia bark, a commercial product. Based on the results achieved, we can conclude that the PTR extract is a potential source for application of in the nutraceutical, medical, and pharmaceutical industries.

“…al [1] on the effects of soaking time showed different quality of essential oils yield. There are many studies about pharmacological properties on the agarwood essential oil especially in anti-inflammatory [3], antioxidant [4], antibacterial [5], anti-hyperglycemic [6] and anti-ischemic [7]. However, only few research had been done for the identification of sesquiterpenes which believe have a potential to cure cancer.…”

Agarwood or its specific named, Aquilaria spp. is a precious tree in the world. It has been used widely in pharmaceutical industry, production of perfumes and incense raw material. In this study, the agarwood essential oil, species of Aquilaria maleccensis is being extracted by using hydrodistillation method. This study aims to analyse the present of chemical compound named sesquiterpenes in the agarwood essential oil. The effect of pre-treatment using soaking process on the agarwood within 7 days, 14 days and 21 days before proceed for hydrodistillation process had been done. The hydrodistillation process took 3 days before the sample of essential oil is collected. The sample is being analysed by using gas chromatography mass spectrometry (GC-MS). The result showed the existence of sesquiterpenes had been identified from all sample of three batches. However, different types of sesquiterpenes were identified for different batch. The highest sesquiterpenes content for 1 st batch is α-gurjunene with 2.95%, the 2 nd batch is ç-Himachalene with 0.292% and the 3 rd batch is same with the 1 st batch which is α-gurjunene with 0.356%. Keywords: agarwood, Aquilaria maleccensis, Sesquiterpenes, hydrodistillation, gas chromatography mass spectrometry Abstrak Gaharu atau nama spesifiknya, Aquilaria spp. adalah pokok yang sangat berharga di dunia. Ia banyak digunakan di dalam industri farmaseutikal, penghasilan minyak wangi dan bahan asas kemenyan. Dalam kajian ini, pati minyak gaharu, jenis Aquilaria maleccensis di ekstrak melalui kaedah penyulingan air. Tujuan kajian ini adalah untuk menganalisis kehadiran komponen kimia yang dinamakan sebagai sesquiterpenes di dalam pati minyak gaharu. Kesan pra rawatan menggunakan proses rendaman ke atas gaharu dilakukan antara 7 hari, 14 hari dan 21 hari sebelum dilanjutkan ke proses penyulingan air. Proses penyulingan air mengambil masa 3 hari sebelum sampel pati minyak gaharu diambil. Sampel tersebut tersebut seterusnya dianalisis menggunakan kromatografi gas spektrometri jisim (GC-MS). Keputusan menunjukkan kehadiran sesquiterpenes daripada ketiga-tiga kumpulan. Walau bagaimanapun, jenis sesquiterpenes berbeza dikenalpasti bagi setiap kumpulan. Kuantiti sesquiterpenes paling tinggi dalam kumpulan pertama ialah α-gurjunene iaitu 2.95%, kumpulan kedua ialah ç-Himachalene iaitu sebanyak 0.292% dan kumpulan ketiga adalah bersamaan dengan kumpulan pertama iaitu 0.356%.
