<p><strong>Evaluation of phenols and lignin in the root of hybrid patchouli (Pogostemon cablin Benth.) front protoplast fusion</strong></p><p>One of the problems faced in patchouli production is nematode infection (Pratylenchus brachyurus). Improvement of the plant resistance to nematode in patchouli is dificult 10 be conducted through conventional method as the plant never llowcrs. One of the methods of improving (he plain resistance is by using protoplast fusion of Aceh patchouli (Pogostemon cablin, cv Sidikalang ) and Java patchouli (/' heyneanus. cv (iirilaya). It has been found thai Ihe plain resistance lo nematode is closely related to phenols and lignin content of the root Therefore. Ihe level of resistance of different clones of somatic hybrids lo nematode was approached by evaluating ihe content of phenols and lignin of the roots The study was conducted al the laboratory of the Research Institute for food Crop Biotechnology, Bogor in November 2000. Phenol content was determined with high performance liquid Chromatography (IIPI.C). while lignin content was determined with Klasou method. Result showed that Java patchouli (Girilaya) contained phenols and lignin respectively 76.53 and 21 900 pp. higher than those of Aceh patchouli (Sidikalang and Tapak Tuan) respectively 38 2-81 45 and 8 000-7 200 ppm. Phenol and lignin content in the somatic hybrids were dilferenl in Ihe respective pairs. In the fusion of Girilaya x Sidikalang. all clones contained phenol lower than those of Iheir parents, some clones (29%) contained lignin higher than Sidikalang but lower than (iirilaya. and the rest (71%) contained lignin lower than the two parents. Meanwhile, from Ihe fusion of Girilaya, Tapak Tuan. I clone (4%) contained phenols higher than those of (he two parents (97 ppm). 39% contained phenols higher than Tapak Tuan but lower than Girilaya (38.75-60.12 ppm) and the rests (60%) contained phenol lower than the two parents. Furthermore, the lignin content, of 78% somatic hybrids was lower than Girilaya but higher than Tapak Tuan, but the rest (22%) was lower than the two parents. Based on the distribution of phenols and lignin content. Ihe somatic hybrids can be categorized in three group The irst groups (5 clones) contained high phenols (higher than the average). Ihe second group (9 clones) contained high lignin. and Ihe third (I clone) contained high phenol and lignin.</p>

Schisandra Chinensis Baill from four places were extracted with superficial CO2 fluid extraction (SCDE) to explore the component differences based on regional. The condition of SCDE for Schisandra oil are: 18 MPa extraction pressure 6 Mpa , extraction temperature 40 °C and separate temperature for 90 minutes. The Schisandra oil were analyzed by high performance liquid chromatography (HPLC), using the oil yield and the lignin content as the quality index of the Schisandra. The results will be compared with the results of organic solvent extraction. For the extraction of Schisandra oil, SCDE is superior to the organic solvent extraction. The component differences of the Schisandra oil from four different places are obvious, and the oil yield and the lignin content of Schisandra from Changbai Mountain in Jilin Province is the highest.

Vitamin A deficiency is still one of the major public health problems in least developed countries. Fortification of vegetable oils is a strategy implemented worldwide to prevent this deficiency. For a fortification program to be effective, regular monitoring is necessary to control food quality in the producing units. The reference methods for vitamin A quantification are expensive and time-consuming. A rapid method should be useful for regular assessment of vitamin A in the oil industry. A portable device was compared to high-performance liquid chromatography (HPLC) for three plant oils (rapeseed, groundnut, and soya). The device presented a good linearity from 3 to 30 mg retinol equivalents per kg (mg RE.kg- 1). Its limits of detection and quantification were 3 mg RE.kg- 1 for groundnut and rapeseed oils and 4 mg RE.kg- 1 for soya oil. The intra-assay precision ranged from 1.48 % to 3.98 %, considered satisfactory. Accuracy estimated by the root mean squares error ranged from 3.99 to 5.49 and revealed a lower precision than HPLC (0.4 to 2.25). Although it offers less precision than HPLC, the device estimates quickly the vitamin A content of the tested oils from 3 or 4 to 15 mg RE.kg- 1.
